The design tool is free. You only pay for the pieces that make it real — permits, engineered plans, and contractor coordination.
The curved, glazed Solarship arch — from a cover over a heat pump to a whole home in a dome. Captures winter sun, shades summer heat, works on the home you already own.
Buried pipe that pre-heats incoming air in winter and pre-cools it in summer using the ground's steady temperature — cutting the load on your HVAC or heat pump. Standalone, or paired with a Sophab under a patio.
Retractable white tarps on a simple pulley track inside the arch — pulled across to reject summer heat, opened in winter to let the sun back in.
Find your home on a map, and we check every wall for sun exposure, buildable room and shading — then model a Sophab on it with a real cost estimate.
We adapt the stamped HalfPhab Arch engineering set to your exact dimensions — the sealed drawings your municipality needs.
We assemble and submit the building-permit package for your municipality, so you don't have to decode the bylaws.
We share the plans and estimate with vetted local builders and help you compare quotes and schedule the work.
From a compact heat-pump cover to a full-house arch — sized to your wall, budget and how much sun your site gets.
Search or drop a pin on a free map — satellite or street — and we pull your building footprint and lot lines.
We assess each wall for sun, trees and room within your property lines, then recommend the best one.

Upload photos from the yard and we overlay the true geometry so you can picture it in place.
