Survey
Measure openings, swing, clearances and adjacent finishes — plaster or panels prepared for flush frames where specified.

You want interior doors that read as architecture — flush to the wall, quiet in use, finished with hardware that disappears. We specify, supply and install interior doors as part of the same ACJ Lux chain as kitchens and turnkey.

Measure openings, swing, clearances and adjacent finishes — plaster or panels prepared for flush frames where specified.
Frame type, leaf finish and hardware lock as one system before workshop — no late catalogue add-ons.
Workshop prep of leaves and edges — typically weeks after openings and finishes are confirmed.
Install and adjust gaps sequenced with adjacent joinery — quiet close under one programme.
Doors often arrive as catalogue leftovers — thick frames, filler panels, mismatched hardware. The need is openings that hold the room’s line from corridor to bedroom without visual noise.
Clearances, swing, and frame type are locked to measured openings and adjacent finishes — flush, rebated or framed — before hardware is chosen.
Leaves, edges and handles are finished as one system: veneer, lacquer or painted flush, with workshop production and on-site adjustment under the same desk.




Corridors and rooms stay calm — doors sit in plane with walls, gaps stay intentional, hardware stays quiet.
One accountable path from survey to hung door — not a separate supplier fighting the joinery.

Yes — invisible frames sit in plane with plaster or panelled walls when the opening and finishes are prepared for them. We confirm that early in the survey.
Yes. Levers, roses and locks are selected with the finish language so the door does not look like a separate catalogue add-on.
That is the point — doors, kitchens and turnkey stay under one ACJ Lux desk so junctions stay intentional.
Lead time depends on leaf finish and frame system. We lock a programme after survey so site and workshop stay aligned.
