Grissom Lane Zero-Energy Apartments in Blacksburg, Virginia

Developed by CHP in partnership with the Town of Blacksburg, Grissom Lane Apartments is a model of eco-friendly, affordable housing for residents aged 55 years and older.

The design of the new rental community was inspired by a community charrette organized by representatives of the New River Valley Livability Initiative to discuss the meaning of aging in place and conceptualize new intentional housing options for the New River Valley. As a result, CHP Design Studio incorporated Universal Design features throughout the rental community so that residents may live safely, independently, and comfortably for the long term. The development was built by CHP Construction to meet EARTHCRAFT Net-Zero standards to ensure that each home produces as much or more energy than it uses.

Grissom Lane Apartments has four duplex cottages and is managed by CHP Property Management. The site, which allowed the homes to be intimately arranged along a short walking loop, also includes a community garden and central gathering area where residents have the opportunity to create a supportive community.

The development was funded in part by the Town of Blacksburg's Community Development Block Grant Program, the New River Valley HOME Consortium, and NEIGHBORWORKS AMERICA.
