Plan a house extension from feasibility to completion, with budget, quotes and risks tracked alongside.

A planning and project-management checklist written for homeowners preparing an extension. It works through feasibility, design, approvals, tendering, construction and handover in seventy-five steps, and adds a budget and quotes sheet so the money is planned before anything is committed.

Extension Planning Checklist

BUILDPLAN
Who it’s for
  • Homeowners planning a single or two-storey extension
  • Anyone weighing up whether an extension is affordable
  • Owners managing their own designer and builder
How it helps
  • Approvals, party wall and drainage checks are raised before design is fixed
  • Quotes are recorded against a budget rather than considered in isolation
  • Risks are written down while there is still time to act on them
