Real homeowners. Clear planning. Better decisions.

“We felt clear about our budget
from the start”

Join the families who planned their extensions with clarity — before committing to designs or builders.
The real problem is the process — not you
If you’ve ever felt confused, overwhelmed, or worried about overspending while planning your extension, you’re not alone.
Most homeowners are trying to navigate a planning process that’s confusing, out of order, and full of costs that aren’t explained upfront.
It’s not surprising people feel overwhelmed — because this process was never designed to be clear from the homeowner’s point of view.
Most people struggle because they start the extension process in the wrong order — and homeowners are rarely shown the correct order.
The process is backwards from day one - and homeowners feel the impact later.
You’re offered drawings before you understand the real costs.
You’re asked what you want before you know what’s realistic.
You’re encouraged to dream big before you understand your budget.
And this leads to:
Plans that you can't actually afford to build
Extra design fees to fix things that could have been checked earlier
Delays while designs are revised
Confusion about what should happen next
Paying twice for designs that needed correcting
A feeling that “we should have known this — but no one explained it”
You’re not the problem.
The process is broken — and it regularly costs homeowners far more than they expect.
A step-by-step system for planning your extension with clarity and cost awareness
This is why I created the Design to Build Masterclass.
It’s a structured planning system that helps homeowners understand the extension process properly before spending serious money.
It shows which decisions need to happen — and in what order — so you can set a realistic budget and brief your designer with confidence.
The Masterclass helps you:
Understand the process clearly — without relying on guesswork or conflicting advice
Map your true budget using real numbers (not “hope it fits” guesses)
Brief your designer properly — so plans are far more likely to reflect what you can afford
Avoid the redesign trap by checking affordability earlier
Reduce the risk of overspending long before you pay for drawings
Move through each stage with confidence and far more clarity
All in a few focused hours - instead of weeks of uncertainty.
Most homeowners are shown a broken process — here’s a clearer way to plan your extension
Budget problems are much harder to fix later.
Most issues start at the beginning — when the order isn’t clear.

❌ The Old Way:
Drawings first - Reality later
Most homeowners follow the traditional process…
They hire an architect, get some drawings made, and hope everything will come together.
But here’s what usually happens...
You pay for drawings before you understand the real costs involved
Builders quote far more than you expected
You discover the plans you’ve paid for aren’t actually affordable
You start again - and pay again - losing time in the process
Each next step feels unclear and harder than expected
Mistakes build up because the correct order isn’t explained clearly
This backwards process regularly leads to unnecessary costs, delays, and rework.
✅ A Clearer Approach:
Design to Build
Instead of starting with drawings, you begin with a structured planning system that puts budget, clarity, and sequence first.
With the Design to Build Masterclass, you’ll:
Understand likely costs before paying for drawings
Follow a step-by-step roadmap that keeps each stage in the correct order
Brief your designer properly so plans are far more likely to reflect your budget
Understand who to hire, when to hire them, and what each stage should realistically cost
Reduce the risk of redesign fees, delays, and unnecessary rework
Move through planning with confidence instead of uncertainty
When planning is done in the right order, professionals work from a clearer brief — and plans are far more likely to stay realistic and buildable.
“We discovered the plans we’d paid for weren’t affordable — Fran helped us understand what needed fixing before we went any further.” (from Jo M.)
The Masterclass shows homeowners how to get plans they can realistically afford to build —
by checking decisions before those plans are drawn.

Why I created the masterclass
I’m Fran. For over 20 years, I’ve helped UK homeowners turn their ideas into home extensions they could actually afford to build — without the usual budget shocks and redesigns.
Over time, one pattern became impossible to ignore.
Homeowners weren’t doing anything wrong.
They were being guided through the extension process in the wrong order.
The most expensive mistake wasn’t poor decisions —
it was paying for plans before anyone had checked what was realistic.
When costs were finally tested, it was already too late.
Plans didn’t match budgets. Redesigns followed. Time and money were wasted.
All that was missing was —
Plans didn’t match budgets. Redesigns followed. Time and money were wasted.
All that was missing was —
Structure and a realistic budget from the start.
That’s what the Home Extension Guide Method provides.
And the Design to Build Masterclass is the complete version of that planning system.
It shows homeowners what decisions need to happen — and in what order — so they can reach the build-ready stage with clarity and control.

Still got questions? Let’s clear them up
Planning an extension is a big decision — and it’s normal to want clear answers before you move forward.
Here are the most common questions homeowners ask before joining the Design to Build Masterclass.
It’s a good fit if you’re planning a home extension and want clarity on costs, sequence, and decisions before committing to design work.
The Masterclass is ideal if you:
Want to understand what your extension will really cost
Haven’t started design yet — or want to make sure you’re doing it in the right order
Feel unsure who to hire, when to hire them, or how to brief them properly
Want confidence before spending thousands on drawings
It’s not about doing everything yourself — it’s about knowing what to do, in what order, so professionals work with your budget, not against it.
Yes — that’s the entire point.
The Masterclass helps you:
Map your true build and pre-build costs using real numbers
Spot budget risks early — before they become expensive mistakes
Brief designers so plans align with what you can afford from day one
Most budget blowouts happen because people design first and reality hits later.
This flips that process.
That’s completely fine — and very common.
The Masterclass helps you:
Sense-check designs before they go too far
Identify where costs may creep up
Re-brief or refine your plans so they stay realistic and buildable
Many homeowners join after early conversations, once they realise they still don’t have cost clarity or a clear roadmap.
No — this is designed specifically for homeowners, not industry professionals.
Everything is explained in plain English, step by step.
You don’t need to understand drawings, regulations, or construction jargon going in — the Masterclass shows you what matters, what doesn’t, and when each decision should be made.
Most homeowners complete the core planning work in a few focused hours, spread over a few days.
This isn’t weeks of videos or homework.
It’s a practical, structured system you can work through at your own pace — and revisit whenever you need.
The principles inside the Masterclass apply to:
Terraced, semi-detached, and detached homes
Side, rear, wraparound, and loft-style extensions
Small upgrades through to larger family extensions
While costs vary by area and complexity, the process, order, and decision-making framework remain the same.
You’re not on your own!
Support is built into your access:
The Home Extension AI Planning Coach for 24/7 guidance
A Personal Feasibility Review to sense-check your project with an expert
Clear tools, templates, and checklists you can return to anytime
Support is built into the system.
That’s exactly why the Ready-to-Build Guarantee exists.
If you follow the steps and don’t reach a clear, build-ready plan, you’ll receive a full refund.
You keep the tools either way.
The Masterclass is built around the UK planning and building process, so it’s most effective for UK homeowners.
That said, many of the principles around budgeting, sequencing, and briefing professionals are universal — but local costs and regulations will vary.
You get instant online access as soon as you join.
You can log in anytime, from any device, and work through the system at your own pace.
The Masterclass is a one-time payment of £147.
There’s no subscription, no upsells, and it’s covered by the Ready-to-Build Guarantee.
