Single and double storey extensions in Wapping. Trusted, professional, 30+ years' hands-on experience.
GS Renovation builds and extends homes across Wapping, an E1 neighbourhood defined by historic warehouse conversions and new-build riverside apartments. With over 30 years of experience in Tower Hamlets, we handle everything from ground-floor and garden extensions on the area's houses to enclosing terraces and reconfiguring flats, always working within the planning and leasehold framework that applies here.

Wapping is dominated by flats, so a conventional rear or side-return extension is only possible on the smaller number of houses and ground-floor maisonettes with their own outdoor space. Where the plot allows, we design single or double-storey additions, dig and pour the foundations, install any steel beams and build up the roof, then complete the full fit-out with kitchens, bathrooms and finishes handled by one team throughout.
For most Wapping flats, gaining space means enclosing a balcony or terrace, converting loft or roof space in an upper apartment, or reconfiguring internal walls rather than building outward. These projects still need the freeholder's licence to alter and managing-agent approval, and any structural change needs building regulations sign-off. We assess what your property and lease actually permit before promising a single square metre of new floor area.
Whether an extension is permitted development or needs a full planning application depends entirely on the property. Many of Wapping's warehouse buildings are listed or sit within conservation areas near the river and the Tower of London, so external alterations there usually require planning permission from Tower Hamlets Council, and often listed building consent. Permitted development rights are also frequently removed or restricted for flats and converted buildings.
We guide you through the whole process, advising early on what is realistic and handling drawings, applications and building control. Where a party wall is shared with a neighbouring property or flat, which is almost always the case in E1, you serve the correct notices under the Party Wall Act. From first sketch to final inspection, you deal with one contractor who understands how building actually works in Wapping.
Homeowners across Wapping choose GS Renovation for extensions because we are honest about what a leasehold riverside property can and cannot do. We coordinate structural engineers, freeholders, managing agents and Tower Hamlets Council planners, manage party wall matters and deliver the build to a high finish. Three decades in East London means no surprises halfway through.
Punctual, worked hard, and did exactly what he was asked and what he said he would do. Overall, a very high quality job. Will use again.

FAQ
Not from us, though there are unknowns and we name them upfront. On an older Wapping property house extensions can uncover wiring, timber or drainage that nobody could see at the E1 survey, and we tell you what we suspect before starting. Anything additional is priced and agreed in writing first. GS Renovation has never treated a surprise as a licence to inflate a Tower Hamlets invoice. Ring 07472 424 226 and GS Renovation will name the likely unknowns at your E1 address. 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.
Generally yes, because there is less to make good. A newer E1 home has regular dimensions and predictable construction, so house extensions spends less time on plaster and joinery than it does in recent developments and converted commercial buildings turned over to flats. The structural stage is similar in both. GS Renovation programmes each Wapping property on what the survey actually finds rather than on its age alone. The Wapping programme reflects the construction GS Renovation finds at E1, not the build date.
You get the scope in writing before anyone starts. The house extensions quotation for your Wapping home lists structure, trades, approvals and making good, and the programme names the weeks and the Tower Hamlets Council inspection points at E1. GS Renovation appoints and coordinates the structural engineer where the design needs one. Aftercare is a phone call to the same number, not a form. Ask on 07472 424 226 about Tower Hamlets aftercare. The five year guarantee on installations applies in Tower Hamlets too.
Permitted development allows building up to the boundary at single storey, subject to height limits at the eaves, but foundations near a neighbour's structure engage the Party Wall Act. On a Wapping plot we check both the planning route and the party wall position before design.
Not problems so much as variables, and they are manageable when found early. House extensions in an E1 property of that age can meet irregular structure or earlier alterations, which is exactly what the Wapping survey is for. GS Renovation prices what is visible and names what is not. Anything discovered later is agreed in writing before we continue. Ask on 07472 424 226 what house extensions at an E1 address in Wapping actually involves in practice.
It is limited. Most conversions are flats with no ground to build on, and many buildings are listed or in conservation areas, so external extensions rarely gain planning permission. More often we enclose a terrace, use roof space, or reconfigure internally. Any option needs your freeholder's licence, and structural work needs building regulations approval. We will tell you honestly what is possible.
Anywhere in the area, and there is no minimum job size. House extensions enquiries reach GS Renovation from across Wapping and East London, and each gets a free survey at the E1 property and a written quotation afterwards. Building control is coordinated with Tower Hamlets Council where the work requires it. Email info@gsrenovationltd.co.uk to get started. Nothing is owed whether you proceed or not. Small jobs at an E1 address are just as welcome here.
