House extension drawings in Newham

Larger home extensions: Newham's prior approval record

Newham's figures for the larger home extension route are worth reading before choosing it. In its latest published year Newham granted 6 larger home extension prior approvals and refused 23. Under that route the council looks only at the effect on neighbours, and the national rule is: 6 m (attached) / 8 m (detached), single storey, height max 4 m; not on article 2(3) land or an SSSI.

A route where refusals outnumber grants calls for care with the neighbour consultation. For a smaller extension the permitted development rule is 3 m (attached) / 4 m (detached) beyond the original rear wall, single storey, and a Lawful Development Certificate in Newham is the written proof that the extension qualifies.

The council has 42 days to respond to a prior approval, after which work may begin if it has not.

Heritage, Green Belt and the constraints check

Newham has 9 conservation areas and 125 listed building entries. A small part of the borough, about 2 per cent, is Green Belt.

Our free constraints check still reads each address against conservation area, listing, Article 4, trees, flood zone and planning history before we quote, because a single protected tree or an Article 4 direction can change the route.

Housing in Newham and what it means for extensions

About 47.1 per cent of Newham households live in a house, and 30.8 per cent own their home. Where the home is let or leasehold, the landlord's or freeholder's agreement may be needed as well as the council's.

Terraced houses average around £458,668 and semi-detached houses £502,633. Domestic gardens cover about 16.9 per cent of the land, so every metre of rear garden an extension takes is a measurable share of what is left.

On the Community Infrastructure Levy, the rule is: Residential extensions and annexes can claim exemption (claim before commencement). The Mayoral CIL rate here is £30.3 per square metre, indexed.

How Newham decides householder applications

The council decided 388 householder applications in its latest published year, granted 86.9 per cent and decided 97.2 per cent within eight weeks or an agreed extension. The fee for a single dwelling is £548, paid to the council.

What the drawings include and what they cost

A Newham extension set shows existing and proposed floor plans, elevations and sections, with location and block plans, from one model. Drawings start at £695 with VAT included, a second MCIAT chartered technologist checks every sheet, and we redraw at no charge if the council asks for changes.
