Framing the Floor at our High Performance House

Corbett Lunsford

Hear Grace and I discuss some of the interesting challenges so far as we begin the framing of the floors and walls of our family’s high performance house in Atlanta.

Geotechnical Engineering for Foundation Footings: Dirt Performance and 4-in-1 Form-A-Drain

Corbett Lunsford

Corbett hired Geoff Hebner of Padstone Geotechnical Engineering to ensure the house being built will stand for a hundred years or more.

In part 2, Corbett shows the grading and leveling process with 6-8" lifts and 4x compaction using a remote-controlled trench roller.

In Part 3, Geoff returns to run a simple geotechnical test on the compacted dirt before pouring concrete, and Corbett finds out he's not as slick as he hopes.

FINALLY, we get to pour the concrete once the footings are finished with rebar, and well-supported per Geoff’s geotech engineering specs.

Tuning the Enclosure of our Atlanta Home Build

Corbett Lunsford

Tour the Off Grid Homestead with Chris Laumer-Giddens

Corbett Lunsford

Last week I made my first site visit to the mountains of North Carolina to start performance testing the #OffGridHomestead. This is an uber-homebuild with LG Squared Architects (now also LG Cubed Builders) and Chris Laumer-Giddens has a lot to show us, even at this rough in stage, with saws running and tractors rumbling around.

2 Years Later: is #TinyLab Still the Highest Performance Tiny House on Wheels?

Corbett Lunsford

Grace and Corbett built the world's highest performance tiny house on wheels in 2016. It was perfect. Then they toured it 13,000 miles across America and let 7,000 people come inside to feel, hear, and smell what perfectly tuned home performance is like.

What's the house performing like now, after all that torture? And under 2 inches of snow in Atlanta, Georgia? See for yourself in this 20-minute tour, complete with testing, demonstrations, and metrics that show Proof Is Possible, even for people who have never built a house before. The #TinyLab is still the undisputed most scientifically superior home performance demonstration in the world, and we sincerely hope others start challenging our work!
