'Unconventional Cohesion' by HOLA Design (Warsaw, Poland) is a  400-square-meter single-story home designed with a mature couple in mind. The owners wanted a home free of boundaries between interior and exterior spaces, as well as between individual rooms. According to their guidelines, the hall seamlessly connects to the lounge area, then flows into the kitchen on one side, and the patio with a pool on the other. Even the master bedroom wasn't separated from the living area. Additionally, with visits from their children and grandchildren in mind, the house includes two fully private guest rooms, each with its own bathroom.
