A full gut renovation and conversion of a multifamily building into a single family townhouse.

​

133 East 91st Street is one of six identical Queen Anne rowhouses completed in 1896 for a local developer John Weber. The building retains its original façade of red brick and brownstone along with a raised stoop and paved entry court, and a 20-ft rear garden.

​

Morozov worked hand in hand with the architect  to seamlessly integrate all new heating/cooling and other building infrastructure into 17.5-foot wide existing shell.

​

Morozov consulted the owner on high performance building strategies, such as passive heating and cooling, insulation and envelope air-tightness, highly efficient domestic water heating and continuous ventilation with energy recovery. With the exception of domestic water heating, the building does not use natural gas or any other fuel for heating, and is cooled and heated with a variable-refrigerant flow system. Highly insulated envelope, and not relying on gas for heating are expected to save 20 metric tons of Carbon Dioxide emissions on an annual basis.
