Two Ways to Build

Option 1 – Owner-Build

Use the complete construction set yourself. Many people hire local crews or subcontractors using our detailed worksheets.

Option 2 – Full-Service

We handle design, permitting, and construction administration from start to finish.

The Horizon Line Vision

Many owners tell us they want to build one Horizon Line for themselves — and then use the experience to start a small construction company and build for neighbors. We designed this system to make that possible.
But our vision goes even further. We believe every family should have the ability to create homes for their growing children and aging parents — keeping families close, generating rental income, and building lasting wealth. The Horizon Line isn’t just about guest houses. It’s about empowering American families to create a better future, one backyard at a time.
We’re building more than guest houses. We’re building stronger families and resilient communities.

Coming Soon: Interactive Customizer

In the coming weeks we’ll launch a full interactive customizer so you can explore every model, style, finish, and option in real time and generate instant pricing.
