Design Development

Design development and technical design

Design development is the stage where an approved concept becomes a buildable project — refined layouts, elevations and sections, technical details, joinery drawings and material specifications, coordinated with consultants and contractors.

The approach

Most design problems appear between the concept and the site. Design development is where they are solved on paper instead of in the building: junctions, thresholds, ceiling and lighting layouts, stone setting-out, and how each material meets the next.

For developers we also take on value engineering and repeatability — the Jubail Island villa was designed as a prototype, with cost estimation so it could be built again without losing its architectural quality.

What this service includes

  • Refined plans, elevations, sections and ceiling layouts
  • Technical details and material setting-out
  • Joinery and built-in drawings
  • Finishes, lighting and hardware specification
  • Design iterations against developer planning regulations
  • Value engineering and cost-informed design decisions
  • Coordination with structural, MEP and landscape consultants
  • Shop drawing and sample review

Who it is for

  • Clients with an approved concept that needs a buildable package
  • Developers needing a repeatable, cost-controlled prototype
  • Owners whose contractor needs clearer information to price and build
  • Projects where architecture and interiors must stay coordinated

What you receive

  • Developed design drawing set
  • Detail drawings and joinery package
  • Material, finish and FF&E schedules
  • Design intent information for tendering
  • Reviewed shop drawings and samples

Process

How a design development commission runs

Full process
  1. 01

    Consultation & brief

    We start with the site, the brief and the way you will use the building — plot conditions, developer or community guidelines, programme, budget range and timeline.

  2. 02

    Concept design

    Zoning, spatial planning and massing, with an early material and colour direction. You see the idea in plan and in three dimensions before anything is fixed.

  3. 03

    Design development

    Layouts, elevations, sections and visualisation are refined together until proportion, circulation and light are right — and the scheme meets the authority or developer requirements.

  4. 04

    Detailed design & FF&E

    Technical drawings, joinery details, finishes, lighting and furniture specification — the package a contractor and joiner can build from without guesswork.

  5. 05

    Coordination on site

    We work alongside consultants, suppliers and contractors, reviewing shop drawings and samples so the built result matches the approved design.

FAQ

Design Development — common questions

What is design development in an interior or architecture project?

It is the stage between an approved concept and construction. Layouts, elevations, sections and details are refined, materials and fittings are specified, and the design is coordinated with the other consultants so it can be priced and built accurately.

Can you take over a project that another designer started?

Yes, provided the existing design is documented well enough to build on. We review what exists, tell you honestly what is usable, and pick up from the stage the project has reached.

Do you supervise construction?

We coordinate during construction — reviewing shop drawings, samples and site queries against the approved design. Full-time site supervision is carried out by the appointed contractor and engineering consultant.
