See it on your house. Before you spend a penny on drawings.
Upload a photo of your home, see the extension, loft or new windows on it, and get a plain-English planning review that tells you what your council is likely to query — and what to fix first.
Your extension. Your actual house.
Not a showroom, not someone else’s project, not a 3D model that looks nothing like your street. Upload a photo of your home and see the finished works built onto it, with the rest of the house exactly as it is. It is the difference between hoping and deciding.
Find out what your council will say. Before you ask them.
An AI planning review reads your project, checks it against permitted-development (GPDO) and NPPF rules, and researches how your own council has decided similar cases nearby. You get a risk-ranked report in plain English: what is likely to be queried, and what to change first.
Settle the colour argument in a minute, not a month.
Anthracite or cream. Sash or casement. Seeing both on your own house ends the debate far faster than a brochure swatch held up to the window — and you will know before you order, not after.
Something to hand your builder or architect.
A single link with the render, the scope and your notes. Send it to three builders and every quote comes back priced for the same job — so you are comparing prices instead of guessing at what each one included.

They saw it first. Then they built it.
"I saw the rear extension on a photo of my own house before I had spent a penny on drawings. That is what made us commit."
"The report flagged that our dormer was over the volume allowance. We changed it before submitting instead of finding out the hard way."
"We argued about the window colour for weeks. Seeing anthracite and cream on the actual house settled it in about a minute."
"As a self-builder I just wanted to know where I stood with the council before spending on drawings. It told me exactly what to sort out first."
"I sent the render and the scope to three builders. For the first time every quote came back priced for the same job."
