Property Architecture is a practice of MCIAT chartered architectural technologists. We prepare planning and building regulations drawings for homes across London's 33 boroughs and 17 surrounding councils, from Belgravia to Richmond.
Fees are fixed and published up front, VAT included: from £200 for a measured survey, from £745 for householder planning drawings. Every set is checked by a second technologist before it reaches the council.
Nine steps. You choose the design in writing before anything is submitted.
We check the property against conservation areas, listed status, Article 4 directions, tree preservation orders, flood zone and planning history. We choose the right route and send a fixed quote.
We survey the house on one datum: rooms, levels, boundaries, drains, trees and the neighbours' windows that the 45° and 25° tests depend on.
We model the house in Revit and show you options in 3D and plan, with the planning strategy and the precedents in your street.
You choose an option in writing. Nothing changes after this without your say.
A second chartered technologist checks every sheet against the council's validation checklist and the policy. A senior review signs it off before anything is submitted.
We prepare the forms, certificates, fee and documents and submit through the Planning Portal.
We answer the planning officer and make any amendments within five working days, at no charge until approval.
Technical drawings are coordinated with the structural engineer's calculations, the drainage and the planning conditions.
Building control approval, then a next-steps pack covering the commencement notice, party wall timing and CIL.
Free redraws until approval. Every drawing set is checked independently, and the checker is never the person who drew it.

The paperwork next door needs, and a second opinion on drawings you already hold.
One Revit model produces every sheet, so plans, sections and elevations always agree.
Autodesk Revit
Every house is modelled in 3D, like the one above.
The house is modelled once in 3D. Every plan, section and elevation comes from that model.
Back to the modelOur own scripts produce the sheets, title blocks and checks the same way every time.
Engineers, builders and councils exchange files with us in the format they use.
3D visuals show you the design before it is built.
Your engineers and consultants receive the model in an open format.
Online submission to every council.
The energy compliance that building regulations ask for, coordinated with an assessor.

In these areas, conservation areas, listed buildings, protected trees and Article 4 directions are routine. Basements and mansards need the same care. We check each constraint for your address before we quote.

A second technologist checks every drawing set before it goes to the council.
If the council asks for changes, we redraw at no charge.
Every house is modelled in Revit, so plans, sections and elevations agree. Drawings follow in about 7 days after the survey.
Conservation areas, listed status, Article 4 directions, trees, flood zone and planning history are checked before we send a quote.

Some projects fall under permitted development and need no planning application, but conservation areas, listed buildings, flats and Article 4 directions often remove or limit those rights. A Lawful Development Certificate confirms in writing that the work is lawful. We check the property's constraints first, then choose the route (permitted development, prior approval, householder, full planning or listed building consent) before we quote.
Fixed fees start at £200 for a measured survey or floor plans and £745 for householder planning drawings, VAT included. Packages run from £645 to £2,795, depending on what is included. Council application fees are paid to the council separately.
We issue drawings in about 7 days after the survey. The council sets its own decision time, so we cannot promise a date. The statutory period for most householder applications is eight weeks.
No. English law does not require an architect to prepare a planning or building regulations application. Our drawings are prepared by MCIAT chartered architectural technologists, and a second technologist checks every set before it is submitted.
Often, yes: in a conservation area or under an Article 4 direction, work that is permitted development elsewhere may need a planning application. Large parts of Kensington and Chelsea, Westminster and Camden are conservation areas. Trees in conservation areas are also protected. We check all of this before we quote.
Yes. Altering a listed building, inside or out, almost always needs listed building consent, and sometimes planning permission too. Works without consent can be a criminal offence. We prepare the drawings for the application, and councils usually expect supporting heritage information with it.
Often, but both councils have basement policies that limit size and depth and ask for detailed construction and structural information. Basements normally need planning permission and building regulations approval, and sometimes a party wall process. Our basement drawings start from £1,995.
Possibly: the Party Wall etc. Act 1996 requires notice to adjoining owners before certain works, such as excavating near their foundations or building on the boundary. It is separate from planning permission. Our notices and drawings start from £45 per adjoining owner.
Building regulations set how a building is built, covering structure, fire safety, drainage and energy, while planning decides whether a project is acceptable. Most extensions and loft conversions need both. We coordinate private building control where you choose it.
Yes. Every drawing set starts from a measured survey that records rooms, levels, boundaries, drains, trees and neighbouring windows on one datum. The neighbours' windows matter because the 45° and 25° tests depend on them. Measured surveys start from £200, VAT included.
If the council asks for changes, we redraw at no charge until approval, and we make officer amendments within five working days. If an application is refused, we review the reasons with you and can prepare a planning appeal to the Planning Inspectorate. We cannot promise a result, and appeals have strict deadlines.
We cover all 33 London boroughs and 17 surrounding councils across Essex, Hertfordshire, Buckinghamshire, Berkshire, Kent and Surrey. That includes prime areas such as Belgravia, Chelsea, Hampstead, Mayfair and Richmond. Use the coverage map to check your council.
