Project Description:
The Maddox Home compact salt box designed 1,950 sq ft Home utilized elements of the Passive house standard combined with the Living Building challenge and LEED. Creating a space that honors its location on a certified organic farm also lead to many biophilic design considerations including aggressive use of day lighting and natural ventilation.
Another goal of the house was to insure a resilient house that could comfortable be occupied for extended periods of time, in the event of prolonged power outages. This was accomplished through several strategies including low flow 2 button toilets that flush on gravity, a center designed soap stone wood stove, and heavily insulated envelope.
Throughout construction, significant attention was placed on insuring a healthily home and with low or no emitting materials. No foam insulation was used. The house utilized German made Pro Clima products including Mento exterior house wrap and Intello interior vapor barrier. Every joint was taped. The house also used Benjamin Moore Natura zero VOC paints, Vermont Natural coats stains, Green Guard certified glues, and real hardwood from our own property. PVC was minimized and the house utilized a significantly amount of used materials including the Kitchen, interior doors, flooring, fixtures and bricks.
Finally, the house was built for $168 a square foot and construction was accomplished in 9 months.

Materials:
Food centric repurposed kitchen obtained from Green Demolitions.
All flooring on second floor was reposed from craigslist finds
House is also resilient, allowing occupants to stay during prolonged periods of power outages. It is also one of the few houses to be built to a higher standard with hurricane roof clips supporting a metal roof and hurricane brackets into the foundation.
Living & dining rooms utilized oak wood floors from our own property
No dumpster was allowed on site. Waste materials where sorted by owner and most were recycled, reused, or reposed
Significant use of used and repurposed materials: Flooring, Kitchen cabinets and countertops, tile, balusters, brick, interior doors, bathroom vanities, and porch.
Subslab assembly:
Basement slab is insulated with R-15 Extended Polystyrene (EPS)
Above grade wall assembly:
The walls are doubled studded 2x4 construction creating a thermal break and are filled with dense packed cellulose insulation. All joints were tapped with Tescon Vana high performance tape. Exterior of the house is wrapped with Mento, while interior used Intello interior membrane with smart vapor barrier control. All seems were taped.
Flat attic assembly:
2x12 rafters allowed for an R-90 blown in cellulose insulation with mineral wool
