Detail & Build

We take your existing concept design and manage everything that follows, from technical coordination and contractor procurement through to construction delivery and handover.

Starting where your designer left off.

Detail and build is the right model when you already have a concept design from an independent architect or interior designer and need a single, accountable partner to take it through to completion. We pick up the project at RIBA Stage 2 or 3, completing the technical drawings and managing every aspect of the construction process on your behalf.

One partner managing all the complexity.

Detail and build projects involve multiple parties, your independent designer, specialist contractors, consultants and suppliers, all working in parallel. We manage that complexity for you, coordinating every workstream, maintaining clear programme control and acting as the single point of accountability between your design team and the construction process. You stay informed without being drawn into the operational detail.

Protecting your design intent through construction.

The gap between a concept design and a finished space is where design intent can gradually be lost. Specifications get value-engineered, decisions get made under programme pressure and the considered choices made at the design stage can be diluted by the time construction is complete. We ensure that doesn’t happen, maintaining a tight coordination process that protects the integrity of your design from the first technical drawing to the final installation.

Great design deserves great delivery.

When an organisation has invested in an independent architect or designer to create something distinctive, the last thing they want is to see that vision compromised during construction. Detail and build addresses this directly, bringing a single delivery partner into the process who takes full responsibility for translating the design into reality, managing every contractor, every technical decision and every programme risk on the client’s behalf. At Spectrum, we have the technical expertise and delivery rigour to take any concept design and build it to the standard it deserves, ensuring the finished space reflects the vision that inspired it.

Workplaces built around people.

Every project we deliver starts with understanding your organisation, your culture, your people. The spaces we create are well-designed, well-used and still working well years after handover.

Frequently Asked Questions
What is detail and build?

Detail and build is a delivery model where a single contractor takes your existing concept design, completes the technical drawings and manages the full construction process through to handover.

In detail and build, the concept design already exists. The contractor completes the technical resolution and manages construction, rather than developing the design itself.

Spectrum typically get involved at RIBA Stage 2 or 3, once a concept design has been developed by the client’s independent architect or interior designer.

We manage the relationship between the independent designer and the construction process by acting as the coordinating link between them, ensuring every technical decision is aligned with the design intent throughout.

We manage the cost through progressive budgeting, validating cost continuously alongside technical coordination so there are no surprises at contract stage.
