The Cambridge House is a new construction Residence for a family in a historic neighborhood in Cambridge located between Harvard Square and Central Square. This energy efficient, highly insulated, three bedroom house has a master bedroom suite with a roof deck at the upper level and an au pair apartment with a private entrance at the lower level. The living area has an open floor plan that opens up into the kitchen with patio doors that connect directly to the the back yard. Given the urban setting, the house is only 18 feet wide but by incorporating high ceilings and large windows, each living space has plenty of light and air.
