When my wife and I decided to build our next home, my first email was to Martin Holladay. I was familiar with Martin’s 2014 Pretty Good House Manifesto, but wondered if any of his advice had changed. Martin replied to my email, and then updated his manifesto with a new blog post on the topic. We will soon be applying for permits, and hope to be building early in the spring, a house that shares many, but not all of Martin’s suggestions. I worked with my friend, architect, and long-time Fine Homebuilding author Paul DeGroot on the floor plan and elevations, and drew performance and construction details from many projects published at FHB and GBA over the years.
The house is in Climate Zone 5. It’s smaller than average with a 38 ft. by 34 ft. footprint—nearly square in shape. It will have a basement foundation with an “R-3 or better” insulated slab (more on that to come) and walls insulated on the interior to around R-20. There will be with some minimally-finished multi-use space in the basement. It’s a single-story house and, at this point, I’m planning to build 10-in.-thick double-stud walls insulated with dense-pack cellulose.
The roof is a clerestory-style gable framed with raised-heel trusses. There will be no clerestory windows though—the attic will be vented with about 16 in. of blown-in cellulose on the floor. The low-pitch roof isn’t optimized for solar, but there is a large south-facing expanse that I hope someday will be covered with panels. I’m hoping for 1ACH50 or better airtightness and currently plan to air-seal the lid using a variation of a technique recently shared in FHB, with the roof trusses sitting above a sheathed ceiling structure.
There will be a very big, south-facing patio door and…
