Who prepares your planning drawings?

Planning Drawings is a trading name of Property Architecture Ltd, and the practice was founded in 2026. Chartered architectural technologists, each a Chartered Member of the Chartered Institute of Architectural Technologists (MCIAT), draw every set. We carry £2m of professional indemnity insurance, are LABC Partnered and cover all 33 London boroughs and 17 nearby councils. Householder planning drawings start at £515 drawings + £150 survey (£665 total), no VAT to add.

Planning drawings for a London house: six stages from survey to site

Planning drawings are the plans, elevations and sections of your house, as it stands and as you want it, that a council reads when it decides an application. A full drawing set adds the technical drawings for building control and the information your builder needs. These six stages follow one London house through it, with a “from” fee, no VAT to add, wherever a stage has its own price.

What happens before any design starts?

We check your address, then measure the house as it stands. The address check covers planning history, conservation area, listing, Article 4 directions, protected trees and flood zone, so we can choose the route and send a fixed fee. The survey then records rooms, levels, boundaries, drains and trees once, so every later drawing starts from the same numbers.

You get: A measured survey drawing: room sizes, floor and ground levels, boundary lines, drains, trees and the windows of the houses next door.

From £150

Measured building surveys

In the model: Red beams reach the model’s corners and yellow tape lines read off its width, height and depth.

Can I see the design options before I choose?

Yes. We rebuild your house as a Revit model and show you layout options in 3D and as plans, each shown next to its planning strategy and the street’s precedents. You choose one in writing, and from then on nothing changes without your say. Floor plans, elevations and sections for that layout follow.

You get: Design options in 3D and plan, then floor plans, elevations and sections for the layout you choose.

From £225 (floor plans)

Extension and loft drawings

In the model: The model’s floors lift apart and a pale timber extension and loft show the proposed design.

Which planning route fits my project?

Your address and your plans decide the route: householder planning permission, permitted development with an optional Lawful Development Certificate, prior approval or, for a listed house, listed building consent. A chartered technologist who did not draw your set checks each sheet against the council’s validation list, a senior reviewer approves it, and we submit it on the Planning Portal. Changes the officer asks for are redrawn free until approval.

You get: A full application set drawn to your council’s validation list, with location and block plans free inside every planning package.

From £515 drawings + £150 survey (£665 total) for householder planning · £425 drawings + £150 survey (£575 total) for permitted development + Lawful Development Certificate

Planning permission drawings

In the model: Red lines mark the plot and extension, a 45° line leaves next door’s window and three drawing sheets unfold.

What do building regulations drawings add?

Planning asks whether the work is allowed; building regulations set how it must be built. Our technical drawings show how the building goes together, from foundations to roof, and are coordinated with the structural calculations, the drainage and any planning conditions, so your building control body reviews one consistent set.

You get: Building regulations drawings and structural calculations, drawn to agree with each other.

From £515 drawings + £150 survey (£665 total) for building regulations drawings · £389 (structural calculations)

Building regulations drawings

In the model: The model is cut open to show the steel beam, joists, insulation, foundations and a drain run.

Do my neighbours need to be told?

Possibly. Building on the boundary, altering a wall you share with next door or digging near its foundations can mean serving notice on the adjoining owner under the Party Wall etc. Act 1996. We prepare the notices and drawings. After building control approval, a next-steps pack tells you when to give the commencement notice and serve party wall notices, and what the Community Infrastructure Levy (CIL) asks of you.

You get: A party wall notice for each adjoining owner, and a next-steps pack for the start of work.

From £42 per adjoining owner

We can also prepare a tender pack, so several builders price the same drawings, from £945.

Party wall notices

In the model: The neighbouring houses take a soft green tint, dashed lines mark the shared wall and scaffold rises up the side.

What does my builder work from?

One set of drawings that agree with each other. Plans, sections and elevations all come from the same Revit model, so your builder is not left to reconcile sheets that disagree. That set also carries the structural information, the drainage and any planning conditions, ready for pricing and for the site.

You get: The finished drawing set, with calculations and conditions, in a form a builder can price and build from.

After approval we answer your builder’s questions and can visit the site. Fee quoted on request.

In the model: The scaffold lifts away and the extension and loft stand built in brick, tile and glass under golden light.

What do the finished drawings look like?

Two sample sheets for a rear extension, each marked not for construction. The planning sheet shows the existing rear elevation, the proposed rear elevation with bi-fold doors and a proposed side elevation, with a materials note. The building regulations sheet cuts a section through the extension, labels each build-up from foundation to roof and adds fire safety, ventilation and drainage notes.

Why homeowners choose Planning Drawings

  • Checked by someone else. Your set is checked by a technologist who did not draw it, before anything goes to the council.
  • A fee you know first. Fees are published with no VAT to add, and the fixed fee we send after the address check covers the work it describes.
  • One model, no mismatches. Each house is modelled once in Revit and every sheet is cut from that model, so the plan, section and elevation of your extension agree.
  • Free redraws until approval. Officer amendments are turned round within five working days, with no charge for redraws until approval.

Questions homeowners ask about planning drawings in London

How much do planning drawings cost in London?

Householder planning drawings start at £515 drawings + £150 survey (£665 total), no VAT to add. The three packages run £425 to £755 drawings + £150 survey (£575 to £905 total) for permitted development with a Lawful Development Certificate, £515 to £1,235 drawings + £150 survey (£665 to £1,385 total) for planning, and £1,235 to £2,465 drawings + £150 survey (£1,385 to £2,615 total) for complete (planning, building regulations, structural calculations). The council’s application fee is separate. We confirm your exact fee after the address check.

What drawings does a planning application need?

A householder application normally needs location and block plans, plus floor plans and elevations showing the house as it stands today and as you propose to change it. Each council also keeps its own validation list, and an application that omits a listed item can be returned as invalid. We work through your council’s list sheet by sheet before anything is submitted.

Can I build a rear extension without planning permission?

Sometimes. Many rear extensions fall under permitted development, set by Schedule 2, Part 1, Class A of the General Permitted Development Order 2015, which caps their size and height. Flats have no Part 1 rights, conservation areas can narrow them, Article 4 directions can remove them, and altering a listed house also takes listed building consent. We check your address first.

Source: General Permitted Development Order 2015, Schedule 2 (legislation.gov.uk)

What is the difference between permitted development and a Lawful Development Certificate?

Permitted development is a national right to carry out certain work without a planning application. A Lawful Development Certificate is the council’s written confirmation that your specific project falls within that right. The certificate is optional, but it can serve as evidence when you sell. We prepare permitted development drawings with a certificate application from £425 drawings + £150 survey (£575 total), no VAT to add.

Source: Lawful development certificates (GOV.UK) · General Permitted Development Order 2015, Schedule 2 (legislation.gov.uk)

How long do planning drawings take?

About 7 days after the survey. Before that, we check your address, send a fixed fee and measure the house. Once we submit, the council decides in its own time: neither Planning Drawings nor anyone else can promise a date or an outcome. If the officer asks for changes, we make them within five working days and redraw free until approval.

Do I need building regulations drawings as well?

Yes, for most extensions, loft conversions and structural changes. Planning permission settles whether the project may go ahead, while the Building Regulations 2010 set how it is built, covering structure, drainage and insulation among other things. Permitted development does not exempt work from them. We prepare the technical drawings and structural calculations that your building control body checks.

Source: The Building Regulations 2010 (legislation.gov.uk) · Building regulations approval (GOV.UK)

Do conservation areas and Article 4 directions affect my plans?

Yes, they can. A conservation area limits some permitted development rights, and an Article 4 direction lets a council withdraw rights that would otherwise apply, so work that needs no application elsewhere may need one at your address. Which rules apply depends on the exact address, so Planning Drawings looks up conservation area, Article 4 and listing status before quoting.

Source: General Permitted Development Order 2015, Schedule 2 (legislation.gov.uk)

What does a measured building survey include?

It records your house as it stands: room sizes, floor and ground levels, boundary lines, drains and trees, plus the windows in neighbouring houses, which the 45° and 25° daylight tests depend on. Every later drawing is then built on those figures. We price a measured building survey at £150, no VAT to add.
