A little planning up front saves a lot of rework later. Build Sherpas doesn't build. You are the general contractor, and we help you plan the project so the decisions come in the right order.
The lot: zoning, setbacks, utilities, septic or sewer, slopes, and access. For a deeper look, see our site feasibility help.
The plan: how the design lines up with your budget and your skills.
The phase list: the order of work, from site prep to final.
The budget framework: a line-item template by phase with a contingency line. We don't guess costs. Your bids are what count.
Financing questions: how draws and inspections work with lenders.
The permit path: see our Permit Help page for how permitting works.
You walk away with a phase list, a budget template, a permit plan, and a decision list.
