Gundalow multi apartment in New Hampshire

The residential complex consists of 4 identical houses of 5 floors each. The project was created in 7 working days.
This is a fairly typical project for low-rise residential buildings. Each apartment is equipped with a separate ventilation unit with gas heating and a heat pump. The hood in each apartment is made individually and is not integrated into a common shaft.
Exhaust fans for permanent and emergency exhaust are installed in the parking lot.
