Office design, fit out and furniture glossary

Confused by fit out or facilities jargon? Our glossary of common terms can help.

When buying furniture or planning an office move you may find phrases or terms which are not familiar with. Our experts have compiled the definitions below which we hope you will find useful.

Activity-based working

This approach gives employees a choice about how and where they work. In the modern office, this means a variety of settings, each designed for different tasks. Activity-based working came about as a result of private or executive offices being unfit for purpose in many organisations.

Agile working

A phrase that defines what is also referred to as flexible working. But agile working is about more than flexibility in hours of working it also includes location, role and style of work.

Audio-visual systems

The term audio-visual (AV, or A/V) can refer to the equipment used to present sound and visual works. Business presentations are also often audio-visual and office systems can include computers, screens and projectors.

Barcelona chair

A luxury stainless steel and leather chair designed in 1929 and manufactured by Knoll since the 1950s.

Bench desking

Bench desks are office desks that are designed to share structural components such as beams and desk legs. Sharing the components of bench desking not only reduces costs but can also provide a smaller footprint to the office layout as the desktops can be accessed from almost anywhere along the edges.

CAD drawing

Computer-Aided Design (CAD) or computer-aided design and drafting (CADD) is the production of drawings, specifications, and other design-related elements using special graphics and computer programs. May be used for creating floor plans and 3D renders of how an office design will look in practice.


A term used to refer to furniture made of hard materials such as wood, metal or glass. Casegoods is also used to describe quality furniture products that are often delivered already built rather than constructed on-site.

Cat-A fit out

A Cat-A fit out provides a blank canvas. It will typically apply to buildings finished by a developer or before the involvement of a client or interior designer. It will include the essential infrastructure needed for the building to work effectively including lifts, raised floors, suspended ceilings, mechanical and electrical services, washrooms, kitchens, general lighting and other building systems and may also include secondary finishes and features such as window blinds.

It is also defined by what it doesn’t include; generally, the features that make a building unique to a client. So, it will not typically include an interior design, primary finishes and colours, furniture and other interior elements.

Cat-B fit out

A Cat-B fit out provides a home. It incorporates all the features of a Cat A project but includes all those features and services that reflect the specific needs of the organisation occupying the building. It will include interior architecture such as partitions and meeting rooms as well as organisational infrastructures such as IT, office furniture, storage systems and support services such as printers and copiers.

It will also include the primary finishes for the interior including carpets and flooring, fabrics, artwork, manifestations, user-defined lighting and surfaces. It may also include audio-visual systems, break out space, cafes and planting.

In some cases, a developer may contribute to the cost of a Cat B fit out but the main driver is invariably the needs of a specific client occupant.

CAT A+ fit out

A CAT A plus is a midpoint between CAT A and CAT B fit-out. It’s sometimes referred to as a “plug-and-play” office setup which is provided by landlords to new tenants. The CAT A+ is a way of enticing tenants by providing all the elements of the CAT A with some of the perks of CAT B. Where a CAT B is highly tailored to match the tenants brand and corporate culture, the CAT A Plus is more about providing the basics with a few perks – work stations, desks, break out areas, tea points – that could easily be used for a wide range of tenants.

Design and build

It is based on an arrangement in which you partner with one firm to design, manage and deliver the project rather than one in which you have to manage several relationships.
