Questions about structure left in the room
Brick, steel, concrete, and the trim that would hide them.
What counts as exposed structure?+
The members holding the building: joists, beams, columns, and brick piers. They stay in the photograph. Boxing them in ends the style.
Should the brick be painted?+
Leave it bare. Paint is an exception for a damaged patch, not the default. A whitewashed brick wall is a different idea and usually a cover-up.
Where do steel and concrete go?+
Steel is the column, the stair, or the fitting you can name as metal. Concrete is the floor or a worktop, in its own color, not a printed lookalike.
What kind of leather?+
Worn. Creased, dull, already used. A glossy new leather sofa is a finish fight with the brick and the concrete.
Which rooms is this for?+
Lofts, offices, and open kitchens. A formal suite that wants plaster moldings will spend the whole project hiding the very things this style keeps.
What trim is forbidden?+
Crown, casing, and any decorative skin whose job is to hide brick, steel, or concrete. A necessary safety rail is not trim. A soffit built to conceal a beam is.
Can the beam be read from this photograph?+
Yes. The beam, the brick, or the concrete needs to be in the frame. This pass leaves it uncovered. Crown molding and a coat of paint on the brick are the failure.
