01 — The defining detail

20mm. A small measurement that changes the entire view.

The 20mm dimension applies to the meeting stile where two applicable panels meet. The surrounding head, jamb and threshold can be integrated into the building finishes to reduce the visible perimeter and allow the glazing to dominate.

Architectural integration

The frame becomes part of the building.

A layered technical study of how the structure, concealed perimeter, threshold and moving glass are coordinated. Diagrammatic only; final construction follows approved project drawings.

Built into the architecture

Seamless above. Carefully engineered below.

The perimeter frame remains structurally present but can be concealed behind the building finishes. Achieving the cleanest result requires early coordination between the door system, structure, internal finishes, external levels, drainage and waterproofing.
