Built To Breathe

Twenty forgotten ways an American house cooled, heated, dried and defended itself — with no electricity, no ductwork and no thermostat.

Every episode takes one part of the old house — the attic, the cellar, the chimney, the porch, the roof — and counts down the tricks that made it work: what it was, the physics of why it worked, the year it stopped mattering, and where it still survives.

Every method is real, sourced and dated. Nothing invented, nothing romanticised.

The cupola that pulled hot air out of a whole house. The cellar that held winter ice into August. The eaves cut to block July sun and let January sun in.

New episode every day.
