awesome. i think this is one of the most inventive and wonderful layouts for a home. read below from the original post on archdaily for more information Didden Village in Rotterdam, Netherlands- by architects MVRDV.
The bedrooms are positioned as separate houses, optimising the privacy of every member of the family (one for parents and two adjoining children’s rooms). The houses are accessed via a suspended spiral staircase from the loft-like living room. The two spiral stairs to the two children’s houses coil around each other to form a double helix stairs. The houses are placed on the large rectilinear roof surface in such a way that they form a small number of outdoor spaces (houses, squares, streets and lanes) that make up a rooftop village.
