Partially-complete two-storey post and beam addition to passive solar house.

What You Need to Know


Timber frame saltbox addition on north side of passive solar house that was built with SIPs. Has staggered 2×4 studs on 2×6 plates for continuous foam insulation, supplemental radiant heat built into floor, argon-filled windows.

Other Benefits:

Open floor plan

Maintenance Requirements:

About the only maintenance the addition will need is normal cleanup for a house with three teenagers and two dogs. Central vac and open floor plan make cleaning the floor pretty easy.

Efficiency or Sustainability Improvements:

Tankless water heater, centrally-located wood stove (we gather and split the wood ourselves), the entire building is very tight and well insulated.

My Motivation:

I've been a believer in protecting the environment since they called it conservation. It's the lifestyle I want to have. I also really like the zero heating bill in the winter.


I think the most important retrofit you can do is apply caulk to leaks.

Experience with Installer:
