From the first sketch to the last fitting, every interior is drawn to be built as designed.

Interior design

Interiors designed with the engineering, not after it

On many projects the interior scheme is drawn after the engineering is fixed, then cut back on site to fit around it. Our interior designers work in the same team and the same BIM model as our architects and MEP engineers.

Ceilings, lighting, joinery and finishes are coordinated with ducts, sprinklers and structure while the design is still on screen. The contractor receives an Issued for Construction (IFC) package that can be priced and built as drawn.

What we deliver

From the brief to the last finish schedule

  1. 01

    Interior concept design

    Brief, mood boards, zoning and early 3D studies that set the character of each space.

  2. 02

    Space planning

    Layouts, circulation and furniture plans tested against the brief and the way the space will run each day.

  3. 03

    Materials, finishes and FF&E

    Finishes, furniture, fixtures and equipment selected and scheduled, with material boards for client approval.

  4. 04

    Lighting and ceilings

    Lighting concepts, cove details and ceiling designs, set out with the MEP services above them.

  5. 05

    3D visualisation

    Photorealistic renders and VR walkthroughs, so you can review and approve the space before it is built.

  6. 06

    Construction documentation

    IFC drawings, elevations, joinery details and specifications ready for tender and fit-out.

Materials and detail

A room is only as good as its details

  • Materials chosen for daily use. Stone, timber, fabric and metal are selected for wear, cleaning and climate, as well as for how they look.
  • Light that shows the surface. Linear, cove and accent lighting is placed to bring out grain, pattern and texture.
  • Every junction resolved. Where stone meets timber or a ceiling meets a wall, the detail is drawn, so the finished room matches the approved render.
