Honest scope

The Vault is permit-ready in Texas. Other states need a small adaptation step.

Unlike our Skylight Cabin reference plans, the Vault package includes full structural engineering, foundation calcs for hill-country soil, and stamps signed for Texas residential code. If you are building in Texas, this is permit submission ready.

Building in Texas
Buy the package, hand it to your contractor, submit for permit. No additional engineering needed for standard hill-country lots. We answer questions if your AHJ has unusual requirements.
Building in another state
Buy the package as a starting point. Then book a 30-min call. We adapt the engineering for your seismic zone, snow load, and local code (typically $1,500 to $3,500). Your $399 counts as credit.

From a 259-acre Texas ranch.

The Vault Cabin was first drawn for Paraíso Trophy Ranch in Menard County, Texas as part of a four-house community overlooking a quiet creek. Each home is built around a central 702 sq.ft multiuse great room under a steep A-frame ceiling that opens to the sky through four large skylights. Two equal bedroom wings give the floor plan its distinctive cross shape. Outside, deep wraparound porches sit between the wings,one looking to the drive, one looking to the creek,and a fire pit anchors the back porch.
