The Toolkit.
Everything you need to manage your own extension project — without paying architect fees.
One-time purchase. Yours to keep forever.
What is inside
Five tools that took us 9 years to build.
The Budget Master
Pre-formatted Excel/Sheets spreadsheet covering every hidden cost — party walls, skips, building control fees, contingency, and professional fees. The same tool we give our managed clients.
The Professional Brief
A template to help you explain your vision to a builder without getting misquoted. Covers scope, exclusions, timeline expectations, and payment milestones.
The Planning Cheat Sheet
Plain English guide to Permitted Development vs Full Planning Permission. When you need one, when you need the other, and how to check before you spend a penny.
The Spec List
Room-by-room checklist covering every socket, switch, light, plumbing point, and finish you need to specify before the builder starts. Stops the 'I forgot about that' moments.
The Contractor Interview Script
10 questions to ask any builder before you hire them. Designed to separate the professionals from the cowboys — the same questions we use before adding anyone to our vetted network.
This is for you if
You want full control.
- You have done a renovation or extension before

- You want to save money by managing the project yourself
This is NOT for you if
You need professional drawings.
- This is your first building project
- You need actual floor plans drawn (start with our £250 service instead)
- Your project is complex (listed building, major structural work)
