Gable ends are framed to match the main roof trusses, 3,500 lb Douglas Fir assemblies designed and cut by Vermont Timber Frames.
Joists from CanAm Steel support the garage green roof.
Master Carpenter John Bates, CM John O'Keefe and Kris Carr of Carr Concrete double check plans before the walls go up.
Tucking in for the winter
Peter O'Keefe backfills sand to the top of the slab. Under the sand is continuous 2" thick XPS insulation graded away from the foundation, and under that is 3' of crushed stone and footing drains
A Beautiful Slab
The cured slab and utility stubs are ready to be wrapped up for the winter. Come spring we'll be ready to pour the walls.
Pouring it on
Dennis Purinton guides the pour from Tilcon. Four inches of concrete over four inches of XPS foam rest on three feet of compacted stone and vapor barrier. When finished, the entire first floor becomes a thermal sink, moderating indoor temperatures throughout the year.
Master Plumber Jeff Shaw, CM John O'Keefe, Lead Carpenter John Bates and Master Plumber Steve Osella work on the sub-slab utilities.
Hot and cold water PEX supply lines will run free inside flexible polyethylene pipe, which is encased in 4" foam sleeves under the slab insulation, and in rigid conduit above. The large conduit under the elbows is an electrical/data trunk. Once buried in concrete, these utility lines can be upgraded without much fuss in the future, should new pipe and wire technology be developed.
Mike Purinton calls in the mixer to pour the Thermomass frost walls. The aluminum forms go up faster than steel ones and give a nice finish to the concrete.

Getting it right
John O'Keefe and Dennis Purinton get down on the plans. 80% of this slab on grade house is Thermomass concrete, and there is no room for error.
Pete O'Keefe breaks first ground. The topsoil is stockpiled on site and goes into the landscaping next spring.
