Support for UK Developers Building Small to Medium Projects

Over 60% of UK Development Projects Go Over Budget — Yours Doesn’t Have to.

Most UK developments exceed their budget by 20–30%. Worse still, up to 14% face costly delays or get abandoned altogether due to poor planning, unrealistic cost estimates, and lack of expert oversight.

WIth 369 Development Mastery , we help developers save between £60,000 and £180,000on a typical £600K project — while eliminating the stress, confusion, and wasted hours that derail so many builds.

Our Pricing

Mentorship, including access to templates and documents, starts from £4,997.

For our Full Mentorship Programme combined with Remote Project Management & Done-for-You Quantity Surveying Support—our most popular and successful option—prices start from £11,997, depending on the size and complexity of your project.

2. What size budget do I need to work with you?

We typically work with clients whose project budgets range from £250,000 up to several million. We're fully comfortable managing projects up to £10 million, and we tailor our support to suit the scale and complexity of each build.

3. Is this an online course?

No—this is not a generic online course. This is a mentored programme backed by professional QS and project management support. We work alongside you to guide your project from start to finish.

4. Can you help even if I’ve already started my build?

Yes. Whether you’re just starting out or part-way through, we can step in to assess your progress, help avoid further mistakes, and realign your project for success.

5. What kind of support do I get?

You’ll receive expert mentorship, customised templates, weekly check-ins, cost control oversight, construction document reviews, and access to our project management system. You’ll also benefit from our done-for-you QS support—all delivered remotely.

6. Do I need any construction experience to join?

Not at all. Our programme is built for non-construction professionals. We simplify the process and guide you step-by-step, helping you avoid the costly mistakes most self-builders make.

7. What guarantees do you offer?

We guarantee all necessary documentation will meet UK regulations and Building Control standards. Our clients consistently avoid common delays, budget overruns, and compliance issues with our proven approach.

8. What results can I expect?

On average, our clients save £50,000–£100,000 on a £400K build by avoiding budget overruns, delays, and poor planning. More importantly, they finish with less stress, fewer mistakes, and a higher-quality build.

9. Do you offer payment plans?

Yes, we offer flexible payment options, including instalment plans to make the programme more accessible. We can discuss the best option for you during your assessment call.

10. What makes this programme different from hiring a local builder or project manager?

Most builders focus only on construction. We provide end-to-end guidance—from design and planning to cost control, procurement, and quality assurance. Unlike others, we don’t just manage your build—we mentor you to take control, avoid costly mistakes, and build with confidence.

11. What types of construction methods is this programme suitable for?

Our programme supports all construction methods, including traditional brick and block, timber frame, ICF (Insulated Concrete Formwork), modular builds, SIPS, and even container homes. Whether you're building a bungalow or a multi-storey home, our system adapts to suit your chosen method and ensures it's delivered correctly.

12. When is the best time to join the programme?

The earlier, the better. Ideally, you should join before you finalise your design or submit for planning—this allows us to help you make smart decisions from day one. That said, we can still add value at any stage, even if you’ve already started building or hit a roadblock.
