Green On Top
Our inventory of eco-friendly plans got a boost with the arrival of our newest design, Plan 525-1, which is by architect Karl Smith, the latest member of our Signature Studio. His idea was to design an 1,800 sq. ft. three-story, sod-roofed home to fit a tight lot.
The ground floor contains a covered patio, mud room, and guest suite-office;
You can see how carefully thought each floor is, from the wood stove in the ground floor guest room to the walk-in pantry by the kitchen and the master closet with its own island on the top floor. A very elegant and urbane design. According to Karl the sod roof sits over a waterproof membrane of Bituthene (manufactured by Grace Company) and “provides an R-48 U value, and can be supplemented with a layer of rigid insulation in the roof sandwich. The walls are minimum R-16, but that can also be increased, and with insulated glass in the windows, it will more than accomplish most environmental concerns.” I think his roof watering system is clever: it uses reclaimed water pumped from cisterns below French drains.
Another only-at-Houseplans.com sod roof design — this one by Werner Field Architects, Plan 491-5 — takes an opposite tack and is long and low and the living is all on one level.
and blurs the distinction between the natural and the man-made as well as between inside and outside.
A dusk view adds to the green roof although, as the architects explain, the design can work without this feature. We’ll keep adding more “green conception” plans — so instead of letting the grass grow under your feet, why let it grow over your roof!
