The wall is the building

Lay it whole, leave it dark

1
One brick, never cut
Wall, floor and vault share the same engineering brick — the mason adjusts the joint, never the unit, so the surface stays continuous from threshold to ceiling.
2
Mortar carries the rhythm
Broad soot-gray joints, thick and deliberately irregular, do the spacing work — the grid you read is mortar, not a drawn tile line.
3
A room that absorbs light
Matte near-black masonry refuses reflection; daylight enters once, sinks in, and the interior settles into a low, even gloom by design.
4
One russet relief
A single Corten-steel cross is the only warm note — the lone permitted contrast against an interior that is otherwise all brick and shadow.
