Our take. Online-first quote. Higher price point. Strong tech UX. If you're comparing on price alone, get a quote from both — we beat most London architects by 30% on like-for-like scope.


Resi operates as a online residential architecture platform. Which suits you depends on whether you want a defined drawing package at a known price or a broader service.
The drawings and the submission, agreed before work starts. What it never covers is the council's fee, which is statutory and identical everywhere in England: £548 for a householder application, £274 for a lawful development certificate, £249 for prior approval.
| Item | Amount | Paid to |
|---|---|---|
| Extension or loft planning set | from £1,225 | us, fixed |
| Essentials package | from £840 | us, fixed |
| Mansard package | from £1,575 | us, fixed |
| Householder planning application | £548 | the council, statutory |
| Lawful development certificate | £274 | the council, statutory |
| Larger home extension prior approval | £249 | the council, statutory |
| Listed building consent | no fee | the council, statutory |
Sources: our own published fixed fees, and the Town and Country Planning (Fees for Applications) (England) Regulations 2012 as amended, 2026 rates, retrieved 1 September 2026. Statutory fees do not vary between boroughs. Mandatory fee scales for architects were abolished in 1982, so any percentage quoted anywhere is a market convention rather than a published rate.
An online-first residential architecture service, working largely remotely with a survey visit, and offering packaged stages for planning and building regulations.
Where that model is strong: Packaged stages and an online portal make progress visible, and remote working keeps overheads down.
What to establish before you commit: Ask what the survey covers and to what accuracy, whether structural calculations are included, and who attends if the council requests changes.
Every figure below is on our pricing page and does not change with the size of your build. We do not quote a percentage of build cost, because it gives a designer an interest in a larger build.

| Turnaround | 14–20 working days (Essentials, loft); 20–28 (Complete) |

| Positioning | Around 30% below typical London architect rates |
The same ten questions work on either side, and the answers are what actually separate one quote from another.
Statutory fees go to the council, not the designer, and they are set nationally for England. No practice can discount them, so they should appear in every budget identically.
| Householder planning application | £548, 8 weeks |
|---|---|
| Larger home extension prior approval | £249, 6 weeks |
| Lawful Development Certificate (proposed) | £274 |
| Listed building consent | No fee |
| Building control (typical London) | £500–£1,200 |
| Party wall award, agreed surveyor | £900–£1,400 per neighbour |
We publish this comparison because homeowners ask for it. We describe Resi by its business model rather than asserting its current fees or performance — ask them directly and compare the answers against ours. Statutory figures are the England rates in force in 2026 under the Town and Country Planning (Fees for Applications) (England) Regulations.
