The Heritage · W20

Some things were right
the first time.

There is a particular quality to steel from the 1920s — the proportions, the weight of the frame, the way light sits differently against a heritage sightline than a contemporary one. It’s not something you can approximate. You either commit to it or you don’t.

The Heritage W20 commits fully. Inspired by the iconic steel glazing of the early twentieth century and developed to match the Heritage W40 external system, it brings genuine period character to internal spaces without sacrificing the precision or durability that a modern project demands. The result is a door, partition or shower enclosure that feels entirely of its era — and entirely at home in a building that was built in it.

Ultra-slim sightlines, authentic steel detailing and bespoke glazing bar configurations give every installation its own quiet authority. Door heights to 3000mm and partition heights to 4000mm make it as suited to grand architectural gestures as it is to a considered single-room renovation.

Every system is manufactured to order, with individually engineered technical drawings produced for each project.
