A huge white apartment in Amsterdam designed by MAMM. A renovation project of a duplex unit in an 85-year-old building. Living in Amsterdam myself I am curious to know in what area this building is situated. It feels like a mix of an old attic and an office building in one. MAMM opened up the staircase and half of a floor at the upper floor to bring in as much light as possible. i can imagine the view from that roofterrace.
