Wraparound extension drawings in Redbridge

A suburban borough with real Green Belt

66.2 per cent of households here live in a house, and 57.1 per cent own their home. This is a place of semis and terraces with side passages, which is exactly the plot shape a wraparound suits.

Green Belt covers 34 per cent of the borough. That does not touch most suburban streets, but a house backing onto it, or one that sits within it, is judged under stricter policy on extensions, and we confirm the status of the address before drawing.

Redbridge has 16 conservation areas and 134 listed entries, a modest heritage load. Most owners keep national rights, and the first question is whether those rights stretch to the whole wraparound.

Permitted development, prior approval and Redbridge's record

Under national rules the rear part is limited as follows: 3 m (attached) / 4 m (detached) beyond the original rear wall, single storey. The side part is limited as follows: Side extension: single storey, max 4 m high, max half the width of the original house. Either part may fit on its own and the two together may not, because Limits apply to the total enlargement (new part plus any existing enlargement it joins).

For rear depth beyond the basic limit, owners use the larger-home prior approval. In the latest national statistics the council granted 46 and refused 93. Refusals were roughly double the approvals, so the route carries real risk, mainly where an adjoining neighbour objects.

The prior approval does nothing for the side wing. If the design needs both, a householder application covering the whole L is cleaner than splitting the scheme across two routes.

Householder volume and timing in Redbridge

Redbridge decided 991 householder applications in its latest published year, granted 82.8 per cent and decided 94.7 per cent inside eight weeks or an agreed extension.

As ever these are all-project figures. Gardens make up 27.4 per cent of the borough's land, so there is more room to give up than in inner London, but the proposed plan still shows what remains.

Wraparound extension drawings in Redbridge: what you pay and get

The drawing set has existing and proposed plans, sections and elevations with a location plan and a block plan. A second chartered technologist checks the set, and the fee of £1,195 including VAT is fixed in advance. If Redbridge asks for changes before deciding, we redraw at no charge; the council's own fee is £548.

When foundations go deep beside a neighbour's wall, a notice is needed: Adjacent excavation notice at least 1 month before work: within 3 m and deeper than the neighbour's foundations, or within 6 m and cutting a 45° line from their foundations. We mark the relevant distances on the foundation plan. Glazing is capped too: Windows, roof windows, rooflights and doors in an extension should not exceed 25% of the extension floor area plus the area of openings removed or covered. A wraparound with a wall of sliding doors across the back can reach that cap faster than owners expect, so we total the openings before the elevations are finished.
