★★★★★

"Our wraparound extension was approved first time in Lambeth. The drawings were immaculate and the portal meant I never once had to chase for an update."

SR
Sarah R.Rear extension · Lambeth
★★★★★

"They spotted our loft qualified as permitted development — saved us the whole planning process. An architect had already quoted us triple for the same job."

JM
James M.Loft conversion · Ealing
★★★★★

"Fixed fee meant the price never moved, even when the council asked for revisions. Structural calcs were handled in-house, which made the builder's life easy."

AO
Amara O.Double-storey extension · Hackney
★★★★★

"Quote on Monday, survey on Thursday, drawings the following Friday. Wandsworth approved without a single amendment. Ridiculously smooth."

TK
Tom K.Mansard loft · Wandsworth
★★★★★

"Two other firms quoted more and wanted twice as long. These drawings sailed through Islington's conservation team first time."

PD
Priya D.Side return · Islington
★★★★★

"Our builder said they were the clearest drawings he'd worked from in twenty years. The council agreed — approved in six weeks."

Questions

Asked often.

Do I even need planning permission?+
Possibly not — many extensions and lofts fall under permitted development rights. We check your property's eligibility first, and if a full application isn't needed we'll recommend a Lawful Development Certificate instead, which is faster and cheaper.
What's the difference between planning and building regs drawings?+
Planning drawings show the council what the building will look like and how it affects neighbours. Building regulations drawings show how it will be built safely — structure, insulation, fire escape, drainage. Most projects need both; our Complete package covers the two together.
How much do planning drawings cost in London?+
It depends on your property and the scope of the drawings — which is why we quote a fixed fee for your exact project, free, within one working day. The price we quote is the price you pay, and it's set to beat any comparable London quote.
Why use a chartered technologist instead of an architect?+
For residential planning and building regs work, an MCIAT chartered technologist produces the same council-accepted drawings with the same professional accountability — typically at around 30% lower fees. Councils don't score applications by the author's job title.
How long does planning permission take in London?+
Drawings are typically delivered within 7 days of survey. Councils then have a statutory 8 weeks for householder applications. Lawful Development Certificates usually resolve faster.
What is the free approval report?+
Enter your postcode and project and we score your approval odds using live decision data from your borough's planning register — before you spend anything on drawings. It flags conservation areas, Article 4 directions and your council's current approval rate.
Do you cover all London boroughs?+
Yes — we prepare and submit planning and building regulations drawings in all 33 London boroughs, from Camden's conservation officers to Croydon's validation checklists, and track every application through to decision.
What happens if the council refuses?+
Refusals are rare because we review every drawing against your borough's local plan before submission. If it happens, we'll advise on revisions or handle the appeal — we've recovered many refusals at appeal stage.
