Planning and building regulation drawings in Ilford (IG1)
Much of IG1 was laid out at the end of the nineteenth century. The builder A. Cameron Corbett put up the Cranbrook and Grange estates from the 1890s, and the result is long, regular rows of Victorian and Edwardian terraces. Cranbrook Road, Perth Road, Melbourne Road and The Drive are among the district's recorded streets. Around Valentines Park the houses change character: larger bay-fronted period houses sit on tree-lined roads, with Emerson Road running alongside the mansion grounds. On a Corbett terrace the houses share a near-identical footprint, so the house next door is often a close match for your own, and that shapes how an extension is planned.

Repetition cuts both ways. A side-return kitchen or a rear extension on a Corbett terrace has an established footprint to follow, because expectations about rear and side-return depth are settled street by street. Where an application is needed, a scheme that goes well beyond that pattern, or a loft that breaks a long and unbroken roofline, has more to justify. Our drawings for these houses therefore show how an addition reads from the neighbouring gardens as well as the internal layout.
Valentines Park brings its own layer. The Valentines Mansion conservation area wraps the Grade II* mansion, its railings and gate piers on Emerson Road, and the park setting, so anything near that edge needs a closer look before design begins. The mature trees along the park-facing roads are another early check, because several are likely to be protected, and root protection can change where a foundation goes. We establish both the designation and the tree position for your address first, then draw to suit.
Planning in Ilford: what to know before you apply
Redbridge expects extensions and lofts to respect the established building line of the street, and in Ilford that line is often a Victorian or Edwardian terrace. Within a conservation area, roof enlargements, side extensions and rear extensions of more than one storey need a householder planning application rather than relying on permitted development, and Redbridge also has directions that restrict some rights in its conservation areas. Outside a conservation area a terraced house can still use permitted development for a modest rear extension or loft, which we confirm with a lawful development certificate where it helps. The borough-wide Article 4 direction matters if you plan to convert a house for three to six unrelated sharers, since that change of use needs permission. Flats have no householder permitted development rights at all.
Applications are decided by London Borough of Redbridge — its planning pages.
