From the architect: “New York-based studio Architensions has designed House on House, the transformation of a compact suburban home in Babylon, Long Island, which includes the addition of a second-floor volume that makes another home seem like a was placed above the house. “We wanted to ‘hack’ the typology of the American suburban single-family house”, explains the architect and co-founder of Architensions Alessandro Orsini.
“The staircase connecting the first floor and the new addition needed to be compact, but also needed to be a dividing element. Architensions used a discreet cylinder, which allowed the design to be developed from the inside out. externally, the striking geometry of the cylinder seems subtracted from the square volume to create a semi-circular exterior patio facing the street, which extends from the second floor bedroom. This acts as a subversion of the suburban typology, in which decks and patios are introverted toward the backyard, rather than extroverted toward the front.
“The ground floor has been reconfigured, opening up the kitchen and living room and adding an office and guest bedroom. On the new second floor, a large open space is used as the master bedroom, with the cylinder creating an interior partition between The master bathroom is clad in speckled terrazzo and features a shared sink located between the bathroom enclosure and the walk-in closet, rejecting the traditional single-family separation of bed and bathroom and challenging traditional concepts of modesty and privacy. Yellow is used throughout the project to highlight transitions, bring light inside and define spaces.”
