In this minimalist black and white house, modern interior doors from Anyway Doors with invisible window frames were used. The frames are placed on the rough unfinished doorways before the plaster work is carried out. The plasterer then finishes the frames with corner profiles and thus completely hides the frame in the wall finish, so that only the door panel remains visible afterwards. Anyway guarantees carefree installation due to the central mounting. This also makes every door look identical regardless of location or direction of rotation. For the glass doors, a minimalist aluminum block frame was used because of the visible concrete in the entrance hall. This sleek profile ensures a perfect seal around the glass doors and the hinges are attached here, so that nothing needs to be fixed in the floor.
