FAQ

Everything you're about to ask us.

Our phones are busy. Here's what homeowners typically want to know before they book a call.

Before you start

Do I need planning permission?
+
It depends. Most single-storey rear extensions under 3m (semi) / 4m (detached) are "permitted development" — you don't need planning. Lofts in most terraced/semi homes are too, as long as you don't build above the ridge. Conservation areas, listed buildings, and anything fronting a road almost always need it. We check this on your very first call, before you've paid a penny.
Do I need an architect, or will a "plan drawer" do?
+
For most domestic projects — extensions, loft conversions, garage conversions, internal re-configurations — you don't need a registered architect at all. What you need is a team that draws accurate plans, handles planning, and gets you through building control. That's what we do, and we've been doing it since 2008. "Plan drawers" with no formal experience exist — they're sometimes fine for the simplest work, but you're rolling dice on their building-regs knowledge. For more complex new-builds or heavily constrained sites where a registered architect adds value, we'll tell you honestly on the first call.
Can you work on a listed building / in a conservation area?
+
Yes. Heritage statements are included in every package at no extra charge. We've handled Grade II listed cottages, Georgian terraces, and properties in national parks. Tell us on the call and we'll flag the specific constraints up-front.
I'm in Wales — can you still help? What about Scotland or Northern Ireland?
+
We work across England and Wales — both are covered end-to-end, including all planning and building control submissions. We don't currently work in Scotland or Northern Ireland, as the regulatory frameworks there (Scottish Building Standards and Warrants, NI's separate system) differ and are outside our area of expertise. If you're in either, we'd rather be upfront than over-promise.

The process

How does the 3D Home Scan actually work?
+
A Matterport-trained surveyor comes to your house for about an hour with a Matterport Pro2 — a tripod-mounted scanner that captures the whole property in 3D, accurate to within 1% (roughly 4cm at typical room scale). The output is a dimensioned 3D model of your home. You don't need to tidy, move furniture, or do anything to prepare.
Do I need to be present for the scan?
+
Ideally yes, so you can point out which rooms you're thinking about and any quirks (hidden chimney breast behind plasterboard, loft hatch location, boiler spot). But if you can't, we can scan with any adult present — including a builder, family member, or tenant.
How many design rounds do I actually get?
+
One on Essentials, three on Standard, unlimited on Premium. A "round" means a full set of revisions — you can mark up as many comments as you like per round. Most customers use 1–2 rounds; the third tends to be a final "just this one last thing."
Can I talk to the same designer each time?
+
Yes — on every package. You get a dedicated architectural designer for the duration of your project. They lead the design, run the client calls, handle the council submissions, and stay with you end-to-end. No pass-offs, no being handed to a junior mid-project.
What happens if I want to pause for a few months?
+
Not a problem. Your portal stays active indefinitely, your drawings stay on file. We've had customers return after 18 months to pick up where they left off. If you're mid-drafting and pause, we'll park the work and resume when you're ready.

Planning & permission

How long does planning actually take?
+
Statutory determination is 8 weeks from validation. Most councils hit it. Some (looking at you, Wandsworth) run 10–14. Validation itself takes 1–3 weeks. Total average from submission to decision: 10 weeks. We'll submit within a week of you signing off drawings.
What's your approval rate?
+
94% approval across our last 2,000 projects — covering both planning applications and lawful development certificates. The 6% that get refused are usually conservation-area or overly ambitious rear extensions — and we redraft and resubmit those for free.
Do you handle neighbours / party walls?
+
We prepare the statutory Party Wall notices, including letters to adjoining owners. Included on Standard and Premium; £149 add-on for Essentials. We don't chase neighbours for consent — that's between you and them, but we'll tell you exactly what to send.

Money & pricing

Is the price really fixed?
+
Yes. Once you accept your quote, the only thing that changes the fee is a material scope change (e.g. "I'd like to add a loft on top too"). Normal redrafts, council queries, and revisions are all included.
How do I pay?
+
Two options. Pay the full balance up front by card or bank transfer when you accept your quote, or pay a £499 deposit followed by 3 monthly instalments. Instalments don't begin until after your 3D Home Scan and design meeting — no credit checks, no interest.
Do you take payment only when planning is approved?
+
No — the drawings fee is paid up front (or instalments) when you sign up, and the work continues regardless of project stage. This keeps things predictable for you and stops any single stage (like a slow council) holding up the rest.
Can you save me money on my build?
+
We can save you money on bad decisions, which is where most overspend happens. A properly specified steel, an honest kitchen layout, a realistic foundation design — these save thousands when the builder prices it. On Premium we also compare builder quotes formally so you can negotiate.

Building it

Do you recommend builders?
+
Yes — on Standard and Premium. We vet 2–3 builders in your area, share your drawings with them, and collate comparable quotes so you can compare like-for-like. The final choice is always yours. On Essentials you'll still receive a clear checklist of how to vet builders and what to watch for.
Will your drawings be enough for a builder to price accurately?
+
On Standard and Premium, yes — the pack includes a full specification. On Essentials (planning only), the builder will need building regs drawings too before they can price with precision.
What about structural engineering?
+
Included on our Standard and Premium packages — an accredited structural engineer's calculations, coordinated with your drawings. Essentials covers planning drawings only. And remember: your builder's structural engineer is not a substitute — they work for the builder, not you.
What if the builder finds something you missed?
+
If it's genuinely something that should have been in the drawings, we revise at our cost. If it's an unknown (e.g. an uncharted drain found when digging), that's what a contingency budget is for — we recommend 10% of build cost on Standard, 15% on complex projects.
