We’ve compiled 7 in-depth office design ideas to help you think more clearly about your next office fit out or refurbishment. Rather than a list of surface-level tips, each idea here is carefully considered, providing the evidence behind it, the design decisions that make it work in practice, and examples of where we have seen it work drawn from experience and directly from our own client case studies. In fact, every image shown here is a K2 Space project, so if anything jumps out and sparks your interest you may want to get in touch.
1. Hybrid Working
Hybrid working is now the operating model for most London businesses, and the offices that work best have been designed with that reality at their centre, not retrofitted around it. ONS data shows 28% of UK workers follow a hybrid pattern overall, rising to 42% among degree-educated employees. For professional services, financial services and legal firms, the figure is typically higher still.
The challenge is not simply having fewer people in the office on any given day. It is that the same floorplate needs to function well on a quiet Monday when a third of the team are in, and on a packed Wednesday when it is full. Fixed rows of identical desks fail at both ends of that range. The answer is activity-based working: a deliberate mix of settings designed for different tasks, rather than a one-size-fits-all layout.
Give people a choice of where to work
Quiet zones for sustained concentration sit alongside collaboration areas for group work and ideation, informal seating for quick catch-ups, and bookable project rooms for focused team sessions. Lockers replace personal pedestals. A desk booking system prevents overprescription and lets people choose the right setting for the work they are doing that day.
The settings themselves matter as much as the mix. Huddle rooms work when they are genuinely easy to find and book, have decent acoustics and a working screen. Focus zones work when they are separated from high-traffic areas and the etiquette is understood. Neither works if the furniture is uncomfortable or the technology is unreliable.

You may have more space than you think
40 to 60%
London office utilisation
JLL data puts average daily utilisation across London offices at 40 to 60%. Most businesses have more usable space than they realise. A space planning exercise, done before committing to more floor area, almost always uncovers capacity that was hiding in plain sight.
During Criteo’s Global Transformation project for their offices in Paris, New York and APAC we reconfigured underused areas into a broader range of work settings while actually reducing the overall footprint. That kind of result starts with a proper space planning exercise before any design decisions are made.
At Criteo’s London office, reconfiguring underused areas created a wider range of work settings without increasing the footprint.

Our team love the new office, so much so in fact that we have seen a surge in the number of meetings being held here, and also friends coming in to take a look around, which is exactly what we wanted to achieve.

Create a better experience for all staff
Zoning also needs to account for the days when a hybrid team is on a video call with colleagues who are remote. That means camera-ready rooms with clean backdrops, controlled echo and one-touch join, not an afterthought screen bolted to the wall of a room designed for in-person use only.
The best hybrid offices are also designed to evolve. Occupancy data and staff feedback from the first six months will tell you far more about what is working than any initial assumption. We recommend building in flexibility at the furniture and partition level so the layout can be adjusted. For more detail, see our guide to hybrid office design and our article on space planning.
K2 Space has delivered hybrid-first workplaces for clients across financial services, legal, private equity and technology sectors. If you are planning a move or refurbishment and want to understand what an activity-based layout could look like for your team size and working patterns, talk to us.
2. Acoustics
Poor acoustics are consistently one of the top complaints in open plan offices, and the consequences go beyond minor irritation. Research published in the Journal of Applied Psychology found that office noise exposure increases physiological stress and reduces motivation to complete complex tasks. The CIPD links noise distraction directly to reduced concentration, lower output quality and higher reported stress levels among knowledge workers.
The fundamental design mistake is treating acoustics as a single problem to solve rather than a spectrum to manage. A well-designed office is not uniformly quiet. It has deliberately different sound profiles in different zones: a natural hum near the social hub and tea point, controlled speech clarity in meeting rooms, and near-silence in focus areas. These are what we call acoustic neighbourhoods, and getting them right means addressing three distinct layers at the same time.
Three things need to work together
Room isolation prevents sound leaking between spaces. That means proper seals on doors, closing gaps at partition heads, and specifying the right glazing for meeting rooms. Many office fit outs fail here not because of poor products but because of poor acoustic installation.
Reverberation control reduces the bounce of speech off hard surfaces. Open plan offices with polished concrete floors, glazed partitions and hard ceilings are particularly vulnerable. Fabric-wrapped panels, upholstered furniture, curtains and acoustic ceiling baffles all absorb sound energy and prevent the prolonged echo that makes conversation exhausting. The most effective solutions double as design elements: slatted timber ceiling baffles, upholstered feature walls, and soft furnishings chosen partly for their acoustic properties.
Background masking smooths out the distracting spikes caused by a single conversation cutting through an otherwise quiet floor. Sound masking systems emit a gentle broadband signal that raises the ambient noise floor just enough to reduce intelligibility of distant speech, without making the space feel loud. They are particularly effective in large open plan floors with high ceilings.
OSRL’s Southampton meeting suite uses layered materials to deliver speech clarity and acoustic privacy without losing visual transparency. Isolation, reverberation control and material selection all working together.
Get the ventilation right
Focus pods and phone booths are an increasingly critical part of the acoustic toolkit, particularly as voice-based AI tools become more common in daily work. Staff dictating, prompting and reviewing responses out loud create an acoustic load that open plan offices were never built for.
K2 Space works with Framery, Spacestor and Senator to specify pods that match both the acoustic requirements and the design language of each project. Ventilation is the detail that determines whether a pod actually gets used. Stale air after ten minutes can make a pod unusable, regardless of how good it looks.
Wood-slatted soundproof phone booths at OSRL’s 6,000 sq ft Southampton office, positioned just off the main workspace for instant access to private calls. Ventilation was a primary specification consideration. Pods that overheat and become stale after ten minutes simply don’t get used.
Your ceiling can do a lot for acoustics
Ceilings are one of the most underused surfaces for acoustic treatment in commercial interiors. Slatted timber baffles, coloured coffers and suspended panels look striking and absorb reverberation where hard floors and glazed partitions would otherwise create uncomfortable echo.
Avoid glass-on-glass reflections where possible: a meeting room fronted by a glazed partition and backed by another creates a reflective chamber that defeats even good internal acoustic specification. Introduce soft elements at the partition line and use acoustic interlayers in high-spec glazing where budget allows.

For a full treatment of the subject, see our guides on understanding workplace acoustics and reducing noise levels in offices.
3. Meeting Spaces
Meeting rooms remain one of the most contested resources in any office, and one of the most frequently misdesigned. The common failure modes are well documented: rooms that are too large for how they are actually used, AV technology that does not work reliably, acoustics that make remote participants feel like an afterthought, and booking systems that bear no resemblance to how people actually organise their time.
Getting meeting spaces right requires thinking about the full spectrum of how teams meet, from a two-person catch-up to a board-level client presentation, and designing distinct settings for each rather than trying to solve all of them with a single room type repeated across the floor.
Small rooms get used the most. Spec them properly
Small meeting and focus rooms of two to four seats handle the majority of daily use in most offices. They need to be easy to find, easy to book (or available on a walk-up basis), and properly kitted with a screen and power and data connectivity for laptop connections.
Boardrooms and client rooms: first impressions count
Formal boardroom and client presentation suites need a higher quality of finish, better lighting control and a more considered AV setup. For our work with a Mayfair private investment firm, the boardroom specification centred on a custom 9.2-metre Corian table with leather inlay, commissioned artwork and a lighting scheme that could shift between presentation mode and client dining without any visible technology. The brief for these rooms is as much about the experience they create as the meetings they host.

We had a vision of a new office space that supports modern ways of working, inspires our team, and leaves a lasting impression on our clients. K2 Space took our dream and turned it into a masterpiece!

Rooms built for video calls, not rooms with a camera bolted on
Hybrid meeting rooms require a different design discipline entirely. Camera placement at eye level, clean backdrops free from distracting visual noise, controlled echo through soft finishes and ceiling baffles, and one-touch join from any device are the baseline.
AI meeting tools providing live transcription and automated summaries are often a standard in many of our clients’ environments and need to be accommodated in the AV specification from the outset. The biggest trap is treating AV as a retrofit: bolting cameras and screens onto rooms designed for in-person use only will always produce a second-rate hybrid experience.

A place to host clients properly
Client suites adjacent to meeting rooms reduce switching time between pitches, workshops and informal conversations. A small prep pantry, concealed storage for glassware and AV spares, and a lighting scene that can shift from working mode to hosting mode all contribute to the quality of the client experience. For professional services firms, the hosting environment is part of the commercial proposition.

Room booking and utilisation data should inform design decisions from the start. If sensor data shows that 70% of bookings are for two to three people, designing a floor full of eight-person rooms is a known mistake before a single wall goes up. We integrate occupancy data with design strategy as standard. See our guides on space planning and workplace technology for detail on how we approach this.
4. Social Hubs
The social hub is the design element that has done most to distinguish the best modern offices from the worst. It is also the one most often done badly: a tea point with a couple of bar stools, positioned in a leftover corner, that nobody uses except to make a coffee and leave immediately. Done well, it is the most productive square footage in the building.
Gallup research consistently shows that engaged employees are around 17% more productive than disengaged peers, and that social connection at work is one of the primary drivers of that difference. The social hub is where that connection happens: informal knowledge sharing, relationships between teams that rarely meet in formal settings, and the kind of daily culture that no town hall or internal communication can replicate.
17% more productive
Employee engagement
Gallup data consistently shows that engaged employees outperform their disengaged peers by around 17%. Social connection at work is one of the strongest drivers of that engagement, and the social hub is where it plays out every day.
One space, three jobs
The design brief for a social hub has three distinct modes: workspace by day, with cafe-style tables and good laptop connectivity; informal meeting space through the middle of the day, with mixed seat heights for standing catch-ups alongside seated conversations; and social and event space by late afternoon, with integrated AV and enough clearance for a team gathering or client reception. Layered lighting, mobile furniture and an integrated AV setup make the switch between modes effortless.
Position the hub on the main circulation spine, not tucked away at one end of the floor. When it is the natural place to pass through, it becomes the natural place to stop. A good coffee offer, a water point and fast Wi-Fi are the basics. Get those right and the space fills itself.
Lofbergs’ 4,000 sq ft London office, delivered in three months, uses a central social hub as the spine of the floor. Collaborative workspace during the day, gathering point for team events by evening.
Dentsu’s London fit-out uses colour to distinguish collaborative social zones from quieter settings, with vibrant tones in the hub areas giving way to calmer palettes as you move towards focus spaces.
Hosting clients in-house
For professional services and financial services clients, the social hub also functions as a client-facing space. A bar area or servery that allows in-house events (drinks after a pitch, a deal close celebration, a client breakfast) adds a level of polish to client hospitality that external venues rarely match. Plan acoustics and licensing early, use durable and easy-clean surfaces, and have a simple operating plan covering who opens the space, who closes it and where stock lives.
Platinum Equity’s 11,000 sq ft Mayfair office at 5 Hanover Square includes a social and entertaining area that works for client hosting without feeling separate from the rest of the workspace. A modular back bar shifts from coffee to cocktails with minimal changeover.
As always it has been a pleasure working with the K2 team on this project. Their great designs, attention to detail and professionalism have delivered an outstanding office for our team and clients once again.

Somewhere to sit that isn’t a desk
Breakout spaces that sit close to the main workspace, not at the far end of the floor, give people somewhere to step away from a screen for ten minutes without leaving the building. Soft seating, warm lighting and device charging make the difference between a space that gets used and one that gets ignored.
Resimercial design (layered lighting, tactile fabrics and timber tones that create a residential warmth within a commercial-grade frame) is particularly effective in these areas. The best workplaces in 2025 feel more like well-run members’ clubs than traditional offices. The goal is a space people want to come in for, not just one they tolerate because they have to.
The Global Innovation Institute’s 25,000 sq ft London office integrates ergonomic soft seating into multiple breakout zones. Short periods of mental rest close to the workspace, rather than a single dedicated room at the far end of the floor.
See our articles on creative breakout areas and workplace wellbeing for more.
5. Temperature, Air Quality and Thermal Comfort
Thermal comfort is one of the most underestimated drivers of workplace performance, and one of the most common sources of daily friction. Research from Lawrence Berkeley National Laboratory found that poor air quality reduces cognitive performance by up to 9%. Harvard’s COGfx study found that cognitive function scores doubled in offices with enhanced ventilation, compared to those with standard HVAC only. Every 500ppm increase in CO2 measurably slows response times and reduces accuracy on cognitive tests.
For a knowledge business, that is not a marginal consideration. The payroll of most London professional services firms dwarfs the cost of their accommodation. An environment that reduces the effectiveness of that payroll by even a few percent is an expensive problem to ignore.
Fresh air matters more than most people realise
The design response is not simply specifying a better mechanical system, though that matters. It is about the relationship between indoor and outdoor air: whether windows can actually be opened, whether terraces are positioned to allow airflow to reach the interior, whether courtyards and atria create stack-effect ventilation that reduces dependence on mechanical systems during milder weather. When natural ventilation complements HVAC rather than competing with it, the result is a workspace that feels noticeably fresher and more alert.
Connecting indoor workspace to the outdoors through openable windows, terraces and considered airflow design creates an environment that feels noticeably fresher. That is a result that standard HVAC specification alone cannot achieve.
One temperature setting doesn’t work for an entire floor
Thermal zoning is a related issue that most occupants notice immediately but few offices address properly. Different parts of a floor have different solar gain, different occupancy patterns and different equipment loads. A one-size-fits-all HVAC zone will leave perimeter desks too hot on sunny afternoons and deep-plan desks too cold in the morning. The solution is finer-grained zoning at the design stage, combined with occupant control at the desk or zone level where possible.
Netflix Madrid’s workspace, part of a 60,000 sq ft multi-city programme, maximises natural daylight with open sightlines to windows and a layout that allows light to penetrate deep into the floorplate. Natural light and thermal comfort are closely connected: better daylight penetration reduces the heat load from artificial lighting and the cooling demand that goes with it.
Measure what’s happening and let the light do more work
Real-time monitoring makes the invisible visible. CO2 sensors and temperature monitors give facilities teams the data to act before occupants feel the effects, and give occupants themselves the information to understand why a room feels uncomfortable. Dashboard displays showing live air quality data in meeting rooms and common areas are an increasingly standard feature in well-specified London offices, and a straightforward addition during a fit out or refurbishment.
Circadian lighting systems are gaining significant ground in 2025. By mimicking the natural progression of daylight through the day using LED technology, they support natural body rhythms, improve alertness during working hours and aid sleep quality at night. They are now a recognised component of the WELL Building Standard v2 and are increasingly specified by organisations with a genuine commitment to staff wellbeing rather than just a wellness policy on paper. Pair with biophilic design for the best combined effect on focus and comfort.
For organisations in older buildings, a refurbishment is typically the point at which these systems can be upgraded properly. Retrofitting CO2 sensors, upgrading HVAC controls and improving the connection between indoor and outdoor air all deliver measurable returns in occupant satisfaction and productivity. Our team can advise on specification choices that work within the constraints of a listed or older building. Talk to us about your project.
6. Sustainable Design
~40% of global energy
Built environment energy use
The built environment accounts for nearly 40% of global energy consumption and for many of K2 Space’s clients, a sustainable fit-out forms part of that legal requirement.
Under the UK’s Streamlined Energy and Carbon Reporting (SECR) framework, large companies are required to report energy consumption and carbon emissions in their annual reports. This applies to any unquoted company meeting at least two of the following: 250 or more employees, £36 million or more in turnover, or £18 million or more in balance sheet assets. For larger organisations (those with over 500 employees or £500 million in turnover) mandatory climate disclosure under TCFD rules applies on top of that.
Sustainability in office design goes considerably further than specifying energy-efficient lighting, though that remains the most immediate lever available. It covers the full lifecycle of every material used in the project, from sourcing through to end-of-life, and the operational energy performance of the completed space over its lifespan.
What your office is built from matters
Embodied carbon (the carbon emitted in the production, transportation and installation of materials) is the area receiving the most attention in 2025. Specifying FSC-certified timber, low-VOC finishes and recycled-content materials reduces embodied carbon without compromising design quality. K2 Space has long-standing relationships with manufacturers that operate circular programmes and take-back schemes, and can advise on specification choices that reduce waste at the outset.
Circular design principles in practice: modular materials, low-VOC finishes and FSC-certified timber reduce environmental impact without compromising design quality.
Waste less, build smarter
Circular design principles are changing how fit-outs are approached structurally. Modular carpet tiles replaced panel by panel rather than full floor replacement. Furniture designed for disassembly and reuse at the end of its life. Demountable partitions that can be reconfigured without generating waste. These are not aspirational concepts: they are available now, work within standard commercial budgets, and make a meaningful difference to the environmental footprint of a project.
DTRE’s 11,000 sq ft Mayfair office achieved BREEAM Very Good accreditation, integrating sustainable specification across end-of-trip facilities, materials and operational systems. Sustainable design need not mean visual compromise: this project demonstrates that high-quality finishes and responsible specification are entirely compatible.
Plants, timber and a bit of outdoor air
Biophilic design and sustainability are closely related in practice. Natural planting, timber trims and stone textures reduce the perceived need for artificial stimulation, while plants contribute to air quality and occupant wellbeing.
15% higher wellbeing
Wellbeing impact, Human Spaces (7,600 workers)
In a study of 7,600 workers, Human Spaces found that employees in offices with natural elements reported 15% higher wellbeing. Small interventions spread across multiple areas outperform a single statement planter, and maintenance needs to be planned from day one.
Natural planting, timber trims and stone textures spread across the workspace create a restorative environment that supports both focus and wellbeing.
Offices with outdoor space command a 5 to 10% rent premium in London according to CBRE research. Furnished terraces with weather protection, power and Wi-Fi extend the usable floor area and contribute to passive ventilation, reducing reliance on mechanical cooling during warmer months.
Outdoor workspace and green terrace designed for year-round use with weather protection, power access and planting. An extension of the indoor floor rather than an afterthought.
Lower running costs over time
Operational energy performance is the other major lever. LED lighting with daylight-linked dimming, smart building management systems that adjust HVAC and blinds in response to real-time occupancy, and well-insulated partitions all reduce energy consumption over the life of the fit-out. The payback periods on these investments have shortened significantly as energy costs have risen.
K2 Space has delivered BREEAM-accredited projects and can work to a sustainability brief of varying levels of ambition and budget. We will be direct about what is achievable within your programme and what the trade-offs are, rather than making commitments that are difficult to substantiate. For more on our approach, see our article on designing sustainable offices and our fit-out costs guide.
7. Technology
Technology in the modern workplace operates on two levels that are easy to conflate but need to be designed for separately. The first is enabling technology: the AV, connectivity and booking infrastructure that makes the office function. The second is intelligent technology: the layer of AI, analytics and building management systems that make it learn and adapt. Both matter, but failing at the first makes the second irrelevant.
Get the basics right first
Every meeting room in any well-designed London office needs a reliable video bar with one-touch join, camera at eye level, controlled echo and a single cable for laptop connection. Desk and room booking needs to be visible, accurate and simple enough that people actually use it rather than working around it.
Wi-Fi needs to be seamless across the entire floor, including in booths, pods and breakout areas where it is most frequently missing. None of this is complicated, but it requires planning from the design stage rather than being specified as a retrofit.
The 102,000 sq ft Paris headquarters of a Global Tech and Media Company, where smart connectivity was integrated across a listed Hotel Particulier by 32 manufacturers in a four-week install. The project required meticulous coordination of AV, lighting, HVAC and building management systems within the constraints of a heritage building. Exactly the kind of complexity our integrated design-and-build approach is built for.
K2 Space managed the design and build process seamlessly ensuring that there was no disruption to our normal business activities and handed over a fantastic, vibrant new space that our staff love.
Carolyn Kaiser, William Blair
Let the building manage itself
AI-powered building management is where the most significant gains are now being made. Systems that predict peak demand, release no-show bookings automatically, adjust HVAC and lighting in real time based on occupancy, and recommend optimal desk clusters for project teams are now available and proven in commercial environments. The energy savings alone typically justify a meaningful portion of the implementation cost.
Make the important stuff visible
Technology walls and large-format dashboard displays serve a different but related purpose. In trading environments, media companies, creative studios and any organisation where the current state of a project or market needs to be always visible, a well-designed technology wall removes the overhead of scheduled alignment meetings. Pair with a standing zone and adjacent collaboration space so passive information display can shift into active decision-making without anyone having to move floors.
Technology walls integrated into the Paris headquarters, allowing trading teams and project groups to see critical information and move into active decisions without scheduling a meeting to discuss what everyone can already see on a screen.
AI tools need somewhere quiet too
AI-ready private settings are an emerging design requirement that is moving fast. Gensler research found that employees who use AI tools heavily actually report stronger team relationships and spend more time in collaboration than their peers. The AI handles individual processing tasks, freeing people for the conversations that benefit from human interaction. But voice-based AI interaction (dictating, prompting, reviewing responses out loud) creates an acoustic load that open plan offices were never built for. Single-person pods, two-seat booths and small enclosed rooms positioned close to the main workspace give people somewhere to interact with AI without disturbing colleagues or being overheard on sensitive matters. K2 Space works with Framery, Spacestor and Senator to specify pods that meet the sustained ventilation and acoustic requirements this kind of regular use demands.
William Blair’s London office, part of a 20,000 sq ft Frankfurt and London programme, provides a range of enclosed and semi-private settings. As voice-based AI tools become a standard part of daily work, the acoustic privacy requirements of a floor shift significantly. Offices with sufficient enclosed capacity are already ahead of the curve.
Smart navigation technology (digital screens at lift lobbies showing real-time room availability and directions, floor material transitions that signal zone changes, colour-coded areas that give an instinctive sense of location) removes the daily friction of finding a desk or a room in a building that sees a different mix of people every day. In larger buildings or multi-floor organisations, this is the detail that separates a functioning office from a frustrating one.
For AV specification advice, governance frameworks and implementation roadmaps, see our smart office design and workplace technology guides.
