Faced with brightening a dark, oblong apartment, architect Peter Kostelov took an unconventional course of action: he built a giant ‘oak tube.’

The Moscow apartment, located in a multi-story building with a shaded inner courtyard, had little natural lighting, especially within the inner rooms. To bring in light, Kostelov removed solid walls and widened windows. He then raised the middle section of the apartment onto a podium to better catch the light.

These central rooms – the bedroom and office – were then lined with strips of light oak, running from ceiling to floor and creating smooth, cornerless rooms. Shelving and room dividers are built into the walls, while the ends of the ‘tube’ are covered in composite stone.

In the side rooms, granite floors and oak cabinets mirror the aesthetic. The contrasting use of materials also differentiaties private and public rooms.

The result feels like a softly lit ship’s galley or a rooftop sauna – transforming a shadowy  apartment into a stately and unusual home.
