Underhill is a sustainable green-roof home in Rockaway, New Jersey. Engineered to support deep soil on its roof (up to 12"), it has been planted with small trees, shrubs, and other vegetation native to its woodland site. Underhill is uniquely suited to its location, adjacent to the Wildcat Ridge Wildlife Management Area and open space protected under the Rockaway Township Open Space Master Plan.
Phase 1 of the project brought Underhill past the halfway point in its construction. It included:
- Design, revisions, and building permit
- Tree clearing
- Excavation (including rock splitting)
- Temporary electric
- Installation of main drain
- Footings and most below-grade walls
- Partial waterproofing, insulation, and backfill
- Bedroom floor joists
- Most above-grade walls
- Living room roof (structural only)
- Main roof beams
Phase 1 concluded with the ceremonial installation of the namestone "Underhill" over the front door:
Phase 2 is partially complete. It includes
- completion of structural walls (95% done)
- completion of structural roof (70% done)
- waterproofing & insulation (90% done)
- doors & windows (70% done)
- backfill (85% done)
- installation of vegetation on roof (60% done)
- well & septic (0% done)
Phase 2 requires and additional $40,000. Here's the challenge: because Underhill's design is pioneering, lenders can't find "comparables" on which to base a valuation, and so it hasn't been possible to secure traditional financing for the project. An effort from many sectors of the community has been, and will be, the way to make this innovative green design a reality: corporate sponsors, local businesses, individual donors, neighbors, and friends.
