The Hanvey House includes a renovation of 885 ft2 of the home's original interior and a 300 ft2 addition, as well as 435 ft2 of unmodified space. The new addition features a highly functional design that uses space wisely.

Environmental Aspects

Minimizing environmental impacts was a key consideration during the planning and execution of this project. One of its strongest environmental features is the design's efficient use of space, which allows for a smaller structure. This and other design features such as careful construction waste management, high-quality construction methods, and the use of durable materials and fixtures help to keep the project's ecological footprint to a minimum.

A stormwater management system and the use of crushed stone on pathways and swales allow groundwater to recharge the site. Topsoil and other excavated materials were protected to minimize erosion during construction and reused on site. Three-fourths of the site's native vegetation was preserved and replanted as landscaping. Rainwater is retained in a rain barrel on site for use as irrigation.

Low-flow fixtures, including dual-flush toilets, reduce the home's potable water use by nearly half. Energy use is reduced through several strategies, including good insulation and efficient appliances. Materials were selected, when possible, for their long lifecycles, local production, and contribution to good indoor air quality.
