Interiors are designed as part of the building rather than applied to it afterwards. Ceilings, lighting, joinery, sanitary ware and finishes are drawn against the same coordinated set as the services behind them, so the light switch lands where the hand expects it and the duct never fights the ceiling it shares a void with.
That is the advantage of an interior drawn by the same practice that drew the shell. There is no gap to negotiate between the architecture and the fit-out, because there is no seam — the plan form, the daylight and the surfaces are one argument carried through to the last fitting.
We work equally on interiors for buildings we designed and on fit-out within a shell built by others — common for tenancies, refurbishments and changes of use. The scale changes; the care with light, surface and detail does not.
