Cascade Lane

Cascade was constructed and sold as a spec home, neighboring two other TC Legend Houses from the
earlier days of Ted’s green construction career. The home is nestled in the steep hillside with the driveway and most of the house standing on stilts. The area is notorious for almost inaccessibly steep driveways, so to create a usable flat driveway at street level and eliminate concrete retaining walls, the 24’ wide driveway bridges to the house with the garage located on stilts, on-grade with the main (second) floor. Cascade projects into space with only a small foundation containing the plumbing. This stilt-house configuration substantially reduces the cost to
build from a traditional foundation and leaves the onsite flora largely intact.

From the entry you walk into the open kitchen, living and dining area with views of the green forest all
around. Behind the kitchen is the utility room and first bathroom. On the lower floor are three
bedrooms and a bathroom, with the master able to be re-configured as a Jack-and-Jill. Also on the lower
floor is the laundry which is located under the stairs and a cozy living or work space with a sliding glass
door out to a small deck that can hold your mini vegetable garden. In total, Cascade is 1400 sf with 3
bedrooms, 2 bathrooms and a 240 sf garage.

Built and performing just as all our standard homes, Cascade is a Net-Zero home and will receive a Built
Green 5 star certification along EPA Indoor AirPLUS certification, EPA Energy Star certification and
Department of Energy Zero Energy Ready Home rating.

This 1,200 square-foot two-bedroom clerestory riverside home was built in 2020 in Ferry County, WA. TC Legend designed and permitted the home, and it was built by a Ferry County contractor.

The greater temperature swings associated with the continental climate led us to do a cost-efficiency study to choose the best SIPs panel thicknesses. Walls were bumped to 8 inches, yet the roof remained 10.25 inches. The exposed concrete stem wall footing stands high above the finished grade to keep the snow away from the panel toe, assisted by generous eaves and covered walks & porches, which also provide necessary shade during the hot summers.

An entry mudroom/utility room airlocks the house to minimize the entry of smoke during the fire season. Fresh, filtered air is delivered throughout the house via heat recovery ventilator (HRV), scavenging the heat from the waste air and imparting that heat into the incoming fresh air.

The circular windows are very easy to cut into SIPs panels; the trim-out is a bit more tricky.

This family needed some room for the big kids to spread out. TC Legend Homes designed and built this accessory dwelling unit to meet their needs. The family gained a large garage, with 576 square feet of living space perched above, accessible to the main house via 2nd-story bridge.

Key Features:

  • A simple design to minimize exposed surface area

  • Orientation and window placement to optimize passive solar

  • Insulated concrete forms

  • 2nd floor Structural Insulated Panel construction (vice traditional framing) to reduce possibility of thermal bridging

  • Double-pane windows

  • High-efficiency mini-split heat pump for heating & cooling

  • Energy Star, EPA Indoor airPLUS, and 4-Star Built Green Certified

  • Home Energy Rating System (HERS) Index is 46.  (A typical new home has a rating of + 62).
