Kitchen Extensions Wapping

A kitchen extension in Wapping is a house job, and houses are the minority here: the VOA count records 91% of homes in Wapping as flats and 9% as houses. The same count puts 9% of homes down as terraced houses and 0% as semi-detached or detached. So the work means a single storey rear extension on a terrace, planned around a small yard, a party wall on each side and a kitchen fitted in the same programme. If you own a flat, the starting point is different, because householder permitted development does not cover flats.

In Wapping, a rear kitchen extension of about 30 square metres typically costs £45,000 to £97,500 excluding VAT, or £60,000 to £100,000 for a side return (indicative London ranges, Resi, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Wapping: the structural engineer we appoint designs the foundations and steel, we build the room and fit the kitchen, and a registered electrician certifies the electrics.

What a kitchen extension looks like on a Wapping terrace

On a Wapping terrace the extension goes to the back, straight out across the yard, or wrapping round a rear wing where an older house has one. With 9% of homes in Wapping recorded as terraced houses and 0% as semi-detached or detached, there is no side garden to build into. The width is fixed by the two party walls, so the gain comes from depth and from opening the old back wall into one room. That opening is the structural heart of the job, and the steel that carries the wall above is designed by the structural engineer we appoint.

Access decides much of the sequence on a terrace. Materials, spoil and the steel come through the house, so we plan protection for the hall and stairs before anything is broken out, and we order the steel in lengths that can be carried in. Neighbours on both sides share the walls the new structure is built against or up to. As building owner you serve any party wall notice the work needs, and we give you the drawings and dates to go with it. A narrow yard can mean digging foundations by hand where no machine fits, which shapes the first weeks of the programme.

Housing in Wapping

About 8,650 homes are listed for Wapping, and the mix is 9% houses to 91% flats, with 79% built after 1945, 8% in 1919 to 1939 and 13% earlier. Where most homes are flats, only a ground floor flat in Wapping with its own garden can extend its kitchen.

Permitted development limits for a Wapping house extension

A single storey rear extension on a Wapping terrace can go ahead as permitted development when it stays inside set limits. National rules allow three metres beyond the original rear wall of a house that is not detached, and no more than four metres in height. With prior approval, and outside Article 2(3) designated land, that depth rises to six metres. The figures are measured from the original rear wall, so an earlier extension counts against them. Your designer checks the planning history before anyone draws the depth, because a condition on the permission for a newer estate can remove permitted development rights altogether.

The picture changes inside a conservation area, which is Article 2(3) designated land. Two conservation areas take their names from Wapping: the Wapping Pierhead Conservation Area and the Wapping Wall Conservation Area. Under the national rules every side extension on designated land needs householder planning permission, so a side return infill there becomes a planning application rather than a permitted development job. The owner or their designer makes that application; we build to the consent and supply the construction details and programme the drawings need.

Flats in Wapping and what a kitchen extension means there

If your Wapping home is a flat, householder permitted development rights for extensions do not apply, because those rules cover houses only and not flats or maisonettes. With 91% of Wapping homes recorded as flats, this is the first question to settle. An extension to a flat needs planning permission, and in a block it also needs the freeholder's consent under the lease. For a ground floor flat with its own garden or terrace that route can exist, but it is slow and needs the freeholder, and often the other leaseholders, to agree.

Where extending is not realistic, the same brief can often be met inside the flat by moving the kitchen into the living space, taking out a partition or turning the run onto a new wall. That still needs care. Moving a sink or dishwasher means finding a fall for the waste through a concrete slab or the ceiling void of the flat below, and a new extract route has to reach an outside wall. Opening the kitchen onto the hall can also break the protected escape route that Part B expects in a flat, so the fire strategy is settled first. We plan those runs before the design is fixed.

Building control, drainage and the kitchen fit-out in one Wapping programme

Building regulations approval is needed for an extension and for alterations to the structure, and Tower Hamlets Council inspects the work at the start, at the end and at stages in between. Where the council is your building control body, a commencement notice goes to it at least two working days before work starts. For the council's charge, the structural opening into the new room counts as part of the extension, not as a separate item. On a Wapping job we line up inspections with the moments that get covered: foundations, drainage before backfill, and the steel before it is boxed in.

Drainage and glazing follow in the sequence. A sink on the far side of the new room means extending or diverting the run to the existing drain, and any shared inspection chamber in the yard has to be found early. Roof lights and a glazed rear wall drive the heat loss calculation, so the glass is chosen before the roof goes on. We run the kitchen fit-out as the last phase of the same Wapping programme, so units, worktops, plumbing and electrics go in against walls and floors built for them.

• Wet underfloor heating laid in the new screed
• Flat roofs with rooflights or a roof lantern over the kitchen

Trusted Kitchen Extensions in Wapping

You deal with one firm for the structure and the kitchen, so the steel, the drainage runs and the cabinet layout are planned together instead of passing between trades. We visit, look at the rear wall, the yard and the route through the front door, and give a fixed quote on what we have seen. The structural engineer we appoint designs the steel, and we build to that design and to the approved drawings. We book the building control visits at the stages that get covered, and the kitchen is fitted by the same team that built the room around it.

• Honest updates if a date or a detail has to move
• Old kitchen kept in use until the new shell is weathertight
• Building control and Part P certificates handed over together at the end
