Look at this amazing space with the turn of the century details. The windows are very beautiful and they pop out even more with the dark grey color on them. I like that the heating is painted grey as well, making it a complete window area rather than a separate thing that looks out of place.
The built-in bookcase in the living room is impressive as well, as it goes wall to wall and floor to ceiling. While the walls, windows, and the built-in kitchen all are painted in a tint of grey, the furniture and accessories are in a warmer palette, which makes for a nice contrast.
The natural elements in the living room and kitchen warm up these spaces and the same happens with the beige bedlinen and the brown curtains in the bedroom. The matt black kitchen cabinets contrast nicely with the white subway tile backsplash with black grout and the antique wood shelving warms up this palette nicely.
