East Ham House Extensions

GS Renovation designs and builds extensions across East Ham, where the Victorian and Edwardian terraces of E6 typically have a rear closet wing and a side return waiting to be used. With over 30 years of experience in Newham, we take these projects from foundations and steelwork through to a full finished fit-out.

Steel and new floor joists set out on a rear extension built by GS Renovation at a UK home — The steel seated and the joists hung off it, with the cavity wall closed and scaffold still in place.

Side-return and rear extensions in East Ham

The classic East Ham extension fills in the side return alongside the closet wing, turning a narrow galley kitchen into a wide open-plan kitchen-diner running the full width of the house. We dig and pour foundations that suit the ground and respect the neighbouring terrace, install the steel beams that carry the old rear wall, and tie the new roof and rooflights into the existing structure so the space feels light and connected.

A wrap-around extension takes this further, combining the side return with a rear addition to gain even more ground-floor space on a terraced plot. On these E6 homes we work tight against the party wall, manage the groundworks in a confined garden, and sequence the build so the family can stay living upstairs. Every stage, from footings to plastering, is handled by our own team.

Planning and party walls in East Ham

Many single-storey rear and side-return extensions in East Ham fall under permitted development, meaning no full planning application is needed, though we always check the property's history first because past extensions and any local restrictions can use up those rights. Larger or double-storey schemes, and anything affecting the front elevation, usually need a full planning application to Newham Council. We advise clearly which route your home falls under before design work begins.

Whichever route applies, every extension still needs building regulations approval for the foundations, structure, insulation and drainage, which is separate from planning. Because these terraces share party walls, digging near the boundary or building off the shared wall also triggers the Party Wall Act, so notices go to the neighbours in good time. We manage the planning, building control and party wall strands together so nothing stalls the build.

FAQ

Frequently Asked Questions about House Extensions East Ham

Are there hidden costs with house extensions in East Ham?

No, because everything foreseeable is on the quotation already. House extensions in Victorian and Edwardian terraced housing around E6 occasionally reveals something behind plaster, and when it does we stop, cost it, and get your agreement before continuing at the East Ham property. GS Renovation carries the same approach across Newham. Quotes are free and carry no obligation, whether the E6 property sits in East Ham or the wider East London, and the written figure follows within days. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

Is there room to extend a terraced house in East Ham?

Usually at the rear, and the garden length decides how far. Your East Ham terrace typically has a rear addition with a passage beside it, so infilling that strip and building out behind adds a useful amount without consuming the whole garden. How far out is worth going depends on daylight to the rooms left behind as much as on what permission allows.

What supports the junction between an East Ham house and its extension?

A beam, and often a frame where the opening is wide. Where a new extension at your East Ham property joins the existing house, the rear wall is opened and whatever it was carrying is transferred to a beam sized for the new span. Where there is insufficient masonry at the ends, posts on their own foundations carry the load down instead.

Do new and existing foundations behave the same at an East Ham property?

Not unless they are designed to. New foundations for an East Ham extension are usually deeper than the original ones, and the two respond differently as ground conditions change with the seasons. That is why cracking appears along the junction where it has not been allowed for. The engineer designs the connection between old and new rather than simply butting them together.

Does an East Ham extension need the consumer unit upgrading?

Frequently, because the new space adds circuits the original board was never sized for. An East Ham extension usually brings lighting, sockets, an outside supply and often a kitchen with it, and an older consumer unit may have no spare ways and no modern protection. The work is notifiable and is certified on completion, and the upgrade is priced at the outset rather than discovered at second fix.

What happens to the existing rear door and windows in East Ham?

They usually come out, and their replacement is part of the design rather than an afterthought. Where an East Ham extension covers the original back wall, the old door and windows are removed and the opening formed to suit the new layout. Frames in reasonable condition can sometimes be reused elsewhere. What replaces them affects the daylight reaching the original rooms behind.
