A House That Breathes With the Earth
Why I built Habit Earth Homes—and how its 3D model makes the double shell and passive heating and cooling paths visible.

“Except the LORD build the house, they labour in vain that build it.”
— Psalm 127:1 (KJV)
Most home websites sell finishes. Countertops. Fixtures. Square footage. I built Habit Earth Homes because I wanted to start one layer deeper: with the relationship between the house, the sun, the soil, and the air moving through it.
The idea is simple enough to say and complicated enough to spend years working out. I want a home that behaves less like a sealed box attached to a machine and more like a living system—one that uses shape, insulation, and natural convection before it asks mechanical equipment to solve the problem.
That is what the website is trying to make visible.
A building inside a building
The central form is a Quonset shell wrapped around an insulated living core. The outer arch takes the weather. The inner shell protects the rooms. Between them is a cavity that can buffer temperature and give rising air a controlled path through the building.
I think of it as a thermos you can live inside. A thermos works because the outer surface and the thing it protects are not the same layer. Habit Earth takes that basic separation and makes the space between the layers active.
The 3D model matters because most of the important parts of a high-performance building disappear after construction. Insulation, drainage cavities, vapor control, and air paths all end up behind a finished surface. A rendering that only shows the kitchen would hide the actual idea.
So the model lets the house come apart. Steel skin, ventilated cavity, cellulose, timber frame, greenhouse, rammed earth, and the inner arch can be inspected as parts of one assembly. It is not just a prettier floor plan. It is a way to ask whether the layers make sense together before concrete is poured and walls are closed.
Heating and cooling need a path
Warm air rises whether a designer planned for it or not. The question is whether the building gives that movement a useful path or lets heat stay trapped at the ceiling.
In the current 3D model, high transfer points let warm air move into the crown cavity. A low opening provides the other side of the loop. In summer-purge mode, the upper exhaust opens. Buoyant air leaves high, helping draw cooler replacement air in low.
That is the cooling path the animation is meant to communicate: replacement air enters low, warmer air rises through the cavity, and the heat leaves at the high exhaust.
The heating side begins with the same shell working in the opposite season. Sunlight warms the greenhouse and outer buffer while the insulated inner core slows heat loss from the rooms. Instead of treating the outer shell and the living space as one volume, the model separates them so the air between the layers can be directed according to the season.
This is a diagram of the intended heating and cooling paths, not a promise that convection will magically handle every climate condition. Wind, humidity, pressure, wildfire smoke, occupancy, and the actual site all matter. Fans, dampers, sensors, and filtration still have jobs. The goal is to make the mechanical system cooperate with the physics instead of fighting it all day.
Why put an unfinished idea on the internet?
Because a polished image can make an unresolved system look finished.
The website is a design notebook that happens to be public. The model lets me find conflicts, explain decisions, and change my mind where the details do not hold up. It also lets someone else see the hidden logic and ask a better question than “What color is the siding?”
Some parts are architectural. Some are thermodynamic. Some are still hypotheses that need simulation, prototypes, and engineers willing to challenge them. I would rather show that process honestly than put a green badge on a conventional house and call the work done.
Habit Earth Homes is ultimately about a different relationship with shelter. A home should protect the people inside it, use what the site freely gives, and waste as little as possible. It should be understandable enough that its owners know what it is doing. And if a system fails, the building itself should still be doing real work.
That is the house I am trying to build: not a machine that dominates its environment, and not a fantasy that ignores engineering. A durable middle ground—a home that listens to the conditions around it and breathes with the earth.
