Wraparound extension drawings in Waltham Forest

Boundary heights where neighbours have already built

The height limit applies where there is no neighbouring extension. That qualification is an opening: if the adjoining house already has a side or rear addition, a similar height next to it can be argued, and the evidence is on the neighbour's side of the fence. We measure and photograph the neighbouring extensions from your property and draw them on the block plan and the section.

That evidence has to be accurate, because an officer will check it on site. A neighbour's addition that was built without consent, or one that is a different height from how it looks from your garden, will not support the argument. We say so in the drawing notes when the position is unclear rather than relying on it.

Designations, trees and Green Belt in Waltham Forest

55.1 per cent of households in the borough live in a house and 48.9 per cent own their home. The council publishes 15 conservation areas, 15 Article 4 directions covering 807 mapped areas, and 231 tree preservation orders. Historic England lists 118 entries.

The Article 4 area count is the figure to note. It is large relative to the number of directions, which means a few directions cover many separate polygons, and a house can be inside one without any sign on the building. We check the address against the polygons and the list of directions.

Green Belt covers 22 per cent of the borough. A site within it is judged against stricter policy on extensions, and we confirm the status first.

Permitted development and prior approval

National rights are: 3 m (attached) / 4 m (detached) beyond the original rear wall, single storey at the rear, and Side extension: single storey, max 4 m high, max half the width of the original house at the side. The total is counted across both. The larger-home prior approval route lets the rear go further, and the council's record is weak: in the latest national statistics Waltham Forest granted 31 and refused 87.

Refusals outnumber approvals by a wide margin. Because the new SPD gives a clear wraparound test for householder planning, an application measured against it is often the more predictable path than a prior approval that depends on neighbours staying silent.

Householder decisions in Waltham Forest

The council decided 771 householder applications in its latest published year, granted 81.5 per cent and decided 90.7 per cent within eight weeks or an agreed extension. Not every application is granted or decided on time, which is a reason to submit a complete, well-measured application the first time.

Gardens cover 24.4 per cent of the borough's land, so there is room to build but also a steady pressure on the space that remains.

Wraparound extension drawings in Waltham Forest: scope and fee

The set has existing and proposed plans, sections and elevations, a location plan and a block plan. A second chartered technologist checks each sheet. The fee is £1,195 including VAT, fixed in advance, and we redraw at no charge if the council asks for changes before it decides. The council's own householder fee is £548.

Where your new wall meets a neighbour's, notice is needed: Line-of-junction (new wall) notice at least 1 month before work.
