The new guidance, and why it changes your drawings
The council's current householder document is the Residential Alterations and Retrofit SPD. It replaces the borough's previous residential extensions guide, so old precedents have to be read with care: an approval granted under the earlier rules may not survive the new test.
Alongside it sit the Urban Design SPD and the council's planning guidance on Securing Exemplar Design Quality (planning guidance). The development plan is the Local Plan Part 1: Shaping the Borough 2020-2035, adopted in 2,024.
We read all of these before the first sketch, and we label each design decision on the sheets with the rule it answers.

Constraints that trip people up here
The borough publishes 15 Article 4 directions and 15 conservation areas. Trees add a second layer: the council has published 231 tree preservation orders, which can sit in rear and front gardens.
Historic England lists 118 buildings, 13 at Grade II* and 104 at Grade II, with no entry at Grade I. The at-risk register adds 16 entries.
About 22 per cent of the borough carries green-belt designation. If your house is near it, original floor area becomes part of the case.
Where houses share a rear building line, we measure it on the survey and draw the neighbours' rear walls, so the council can see the effect on light and outlook without asking for more drawings.
Who lives in Waltham Forest, and what they build
The borough has 102,901 households. 55.1 per cent live in a house or bungalow, and 48.9 per cent own their home, so the stock is a mix of owner-occupied houses, rented homes and flats.
A terraced house averaged £624,560 in the latest Land Registry figures. At that level, loft conversions and rear extensions are a common way to add a bedroom and a bathroom.
Because ownership is split, we ask early whether the freeholder, a landlord or a lender needs to see the drawings, and we format them accordingly.
Decision record: householder and prior approval
The council decided 771 householder applications in the latest twelve months and granted 81.5 per cent. It decided 90.7 per cent within eight weeks or an agreed extension.
Prior approval for larger home extensions is where the numbers diverge most: 31 granted and 87 refused. Refusals outnumber approvals by a wide margin, so a full application is often the more reliable route.
These are the borough's past figures and say nothing certain about a single house.
Charges across two levy zones
The Mayor of London's levy puts the borough in band 2. The council's London Borough of Waltham Forest CIL Charging Schedule sets £108.79/m² (Zone A, north of North Circular); £117.15/m² (Zone B, south of North Circular), so the side of the North Circular you live on changes what a new flat or house would pay.
Householder work is usually small enough not to matter, but our next-steps pack confirms it for yours.
We also keep the cost picture honest: our fixed drawing fee, the council's application fee and any levy are three separate items, and we set all three out in writing so you can budget before committing.

What happens after you contact us
We run the address check, quote a fixed fee, survey the house and model it in Revit. You approve a design in writing, a second chartered technologist checks the sheets, and we submit through the Planning Portal.
If the case officer asks for changes, we redraw them free until approval. Your next-steps pack then covers commencement, party wall timing and any levy.
You send an address and a short description. We reply with the constraints we find, a fixed quote and a date for the measured survey. After the survey, you see options before anything is frozen.

Which design guidance does Waltham Forest use now?
The Residential Alterations and Retrofit SPD, which replaced the borough's earlier residential extensions guide. We draw against it.

Householder planning drawings start at £745 including VAT, stated before you commit. The council's application fee is a separate payment to the council.
Does Waltham Forest have Article 4 directions?
Yes: the council has published 15. We check which, if any, cover your street.
Do protected trees affect an extension?
They can. The council has published 231 tree preservation orders, and a protected tree near the build changes where and how we draw.
