site work, new electrical service & pre-foundation work
A passive radon mitigation system is included at the perimeter and will vent through the roof. Note: Since radon levels typically run high in portions of Washington County, this builder believes passive radon mitigation needs to be included in all new construction homes and buildings. Should radon levels test higher than normal after building completion, a radon fan will be placed in the 4" ventilation pipe.
The frost protected shallow foundation consists of two layers of 4" EPS type IX foam board (8" total or R38.4), with 15 mil radon/vapor barrier taped and sandwiched between the two layers of foam. 8"w x 18"h EPS foam blocks make up the non-load bearing wall and eliminates thermal bridging at the slab edge. 24" of tapered wing insulation extends beyond the foam block wall for proper drainage and frost management. The 4" perimeter drain to daylight is set in gravel and wrapped in landscape fabric and backfilled.
12" of compacted soil fills the interior of the foundation after the waste and drainage pipes are installed, allowing for a thickened edge slab of concrete. Carefully placed rebar (measured and marked) on chairs is installed in the house and garage foundations, with 2x4 and Zip Wall bracing to support the foam block walls during the concrete pour. Note: The 2x4's and sheathing were reused for saw horses, rain screen, and window frames.

window and door prep while we wait for trusses
Proper window and door preparation is essential when creating a water resistive system. For this house, a 2-1/2" rip of 3/4" Advantech was applied to the window box where the window will rest on the sill. This "back dam" stops any water from entering beyond the sill, and allows any "Easton" rain (see ...BROUGHT TO YOU BY EASTON below) to drain away from the building. Primed beveled cedar siding is then applied, butting to the back dam to create a positive slope. The window and door openings were then flashed utilizing a "hybrid" method; Liquid Flash at the head and sill and Zip tape on the jambs.

so what's a plenum truss?

Once upon a time, not so long ago (during a pandemic), there were four family members and a neighbor . . .
piggy backs, sheathing and septic system
The septic system was installed by Snell Construction and Septic Services - Harold Snell and sons. Their work was precise and meticulous.

the front porch is born
Note: Under the Sun has been using Techno Metal Posts for over 10 years. It is the much stronger, neater, less labor intensive option to manually digging 4 foot holes!
The front porch includes Douglas fir posts and triple 2x12 beams that were laminated with Liquid Flash at the wall juncture to provide air sealing. The beams were supported by galvanized hangers to reduce framing and thermal bridging in the carriage house. The trusses were lifted into place and secured with TimberLok heavy duty screws. The gable truss was set remotely (controlled from the ground).
a roof coming soon?

a roof at last!
window and front door installation
Backstory: We were introduced to Klearwall windows during the winter of 2017 while touring a Habitat for Humanity Passive House in East Montpelier, Vermont. Thanks to builder Chris Miksic, we were able to see and use the windows in person. We were also super lucky to meet with Klearwall rep Nate, who answered all of our questions while sharing a meal and a Fogal Banger at Prohibition Pig in Waterbury. Since then, we knew our future zero energy homes would include Klearwall windows.
Suction cups are absolutely essential for setting heavy European windows. Since they do not have window flanges to hold on to, carrying the windows by the handles are safer and easier to install, and allows for two or more individuals to carry each window. The 9-footers required four strong people to lift and set!
