Lake Haven Homes

Lake Haven Homes is building four two-family homes on an infill site on Staten Island in New York City. The initial home is part of the NYSERDA Challenge and Lake Haven intends to construct the other three buildings to similar specifications, incorporating lessons learned from the Challenge home. Each home will consists of a four-bedroom owner's unit on two floors and a two-bedroom rental apartment on the ground floor for a total of 3,181 sf plus a one car garage.

The home has been framed and roofed. Presently the mechanical and electrical contractors are roughing in the services. Notable energy features that have been incorporated to date include some aspects of advanced framing (those permitted by NYC Building code and the architect of record), slab insulation, and two-inches of exterior foam insulation.
