Build your own home the way a quantity surveyor would.
Most self-builds go over budget for the same reasons a commercial job does: the cost plan was a guess, the contractor's quote was not read properly, variations were agreed on site with nothing written down, and nobody ran the cash flow. John has spent fourteen years stopping that happening on other people's projects. This programme gives you the same method on yours.
Training, a community, and an assistant that knows your project.
The training
The 16 steps from land to completion, taught in the order you will meet them: cost plan, planning, procurement route, tendering a contractor, the contract, valuations, variations, snagging and handover. Recorded, with live sessions each month.
The community
Other self-builders at every stage, moderated by John. Post the quote you have been sent and get it read properly before you sign it.
The AI assistant
Built inside 369 for self-builders and live in Q1 2027: upload your drawings and quotes, get a cost plan, a programme and a variation log you can actually keep up to date. It is the system John uses, cut down to what a self-builder needs.
£249 a month. Twelve months minimum, then monthly until you are in.
A self-build takes longer than a year, so the first year is committed and after that you stay month to month until the project completes. Founding members join before launch at the launch price for as long as they stay a member.
Prices exclude VAT. Membership is personal to one project. Cancel any time after month twelve.
Founding members get
- First access to the AI assistant in Q1 2027
- A one-to-one cost plan review with John in the first month
- The launch price held for the life of the membership
- A say in what gets built next
From people who have built with John in their corner.

Richard, self-build client
“I can confidently say that engaging John for the contract management and remote project management on my self-build project ranks among the very best [decisions I've made]. If you want to save yourself time, stress, and potential headaches, I highly recommend John.”
“John provided [a] well structured cost plan which helped us stay on track with our budget along the way… Their dedication and professionalism went above and beyond our expectations, and now our dream home is a reality thanks to them!”
“I had a tight deadline to provide costings for my Lender. 369 went out of their way to ensure I had a comprehensive breakdown of costs to build to satisfy the lender. Great to be able to work with someone that doesn't stick to 9-5.”
“John and the team at 369 helped me get over an issue with my planning application for my self-build. 100% would recommend!”
“He listened to everything I said, he understood my situation and needs and his advice was clear, open and above all honest… I encourage new self builders to take up his offer of a free call.”
“John is clearly knowledgeable and experienced in the field and well positioned to help de-risk any developer or self-builder's construction project.”

Two minutes. John reads these and will send a short call link to founding members before launch.
Start with the two documents every self-builder should have.
The 369 Self-Build Cost Plan
The spreadsheet John uses to set a budget before the drawings are finished, with the allowances most people leave out: fees, utilities, contingency, VAT treatment, and the cost of the time it takes.
16 Steps to Build Within Budget
The order of operations from land to handover, and the decision at each step that costs the most if you get it wrong.
Both are sent when you join the waitlist above. Rewritten for 2027; the old 369 downloads are retired.
