We love working with clients to design and build amazing new workspaces.

One of the primary benefits of the design and build model is that it delivers a high-quality fit out at a typically lower cost and quicker turnaround time. D&B projects are typically completed around 30% quicker than the traditional method which includes multiple separate parties. In summary, the benefits of a design and build project include:

  1. Improved Cost Control: It provides the client with a degree of control over costs, as the contractor generally agrees to assume design and construction responsibilities for a predetermined fee. All research comparing building approaches suggests that design-build is much less expensive. Under D&B contracts, cost growth is significantly lower as in the overall cost savings due to minimal conflicts, delays and additional expenses.
  2. Easier to Manage: Having a single point of contact for the customer to interact with after the contract has been granted may also simplify matters.
  3. Quicker Completions: Design and build may be favourable in terms of time, since it permits the overlap of design and construction, hence shortening the total duration of a project’s completion. When your design and construction teams collaborate, the timetable will be much more efficient. This will result in fewer bottlenecks and more concurrent work possibilities. Studies demonstrate that design-build projects are completed up to 33% quicker than typical construction projects.
  4. Reduced Financial Risk: The contractor assumes the majority of financial risk (which may be reflected in the predetermined fee).
