Dormer, hip to gable and mansard loft conversions in Canary Wharf. Trusted, professional, 30+ years' hands-on experience.
GS Renovation covers Canary Wharf and the surrounding E14 docklands, where the housing is almost entirely contemporary apartments. A loft conversion in that stock is not usually possible, and we say so before anyone spends money on drawings. What we do carry out here is the structural and refurbishment work these buildings will actually allow.

The roof of a Canary Wharf block is common structure. It carries plant, membranes, fall arrest systems and often part of the building's fire strategy, and it belongs to the freeholder rather than to the top-floor leaseholder. On most towers there is no void to convert at all, and where a shallow one exists the lease will not grant it to you. That is not a pessimistic reading of your particular building, it is how nearly every modern block in the Docklands is set up.
Owners sometimes ask instead about a mezzanine inside the flat, using the floor to ceiling height in a converted warehouse unit. That is a different job and occasionally achievable, but it is a structural alteration needing the freeholder's licence to alter, Tower Hamlets Council building control, and careful work on escape routes and headroom under Part K. We assess it honestly rather than talk you into it where the height or the escape route does not stack up.
Our loft work belongs on houses, and the nearest of those sit in the older terraced streets of Tower Hamlets rather than on the estate itself. If you own a two-storey house in or near E14, the usual assessment applies: 2.2m to 2.4m from ceiling joists to ridge, a rear dormer or an L-shaped dormer over a closet wing, steel beams spanning between the party walls, and a protected stair route running to a final exit under Part B.
Inside an apartment we are on firmer ground with load-bearing wall removal onto engineer-designed steel, bathroom and kitchen rebuilds, and full refurbishment. Each of those still needs freeholder consent, and building control where structure or fire separation is touched. In a tall block the managing agent will want method statements, working hours and lift protection agreed in advance, and we handle that paperwork as part of the job rather than leaving it on your desk.
Canary Wharf owners choose GS Renovation because we are direct about what a block will and will not permit, then deliver the work that is genuinely achievable. Structural alterations, steel beams, full flat refurbishments and Tower Hamlets Council building control are routine for us.

George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
FAQ
We do not price loft conversion over the phone for Canary Wharf homes. A figure given blind is a figure that changes, so we survey the E14 address, then quote in writing for Canary Wharf. As a rough guide, loft conversion in London runs roughly £30,000 to £45,000 for a rooflight scheme, £45,000 to £65,000 for a rear dormer, £55,000 to £80,000 for an L-shaped dormer or a hip to gable with a dormer, and £70,000 to £100,000 or more for a mansard; an en suite adds roughly £8,000 to £15,000 (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.
Lead time varies with the season and how booked we are. Ring us and we will say honestly when loft conversion could begin at your E14 address rather than promise a Canary Wharf date we cannot hold.
Ask for references on loft conversion and we will give you addresses, not testimonials. Seeing finished work near E14 or across Canary Wharf in person tells you more than anything written down.
Many loft conversions in Canary Wharf fall under permitted development, commonly within 40 cubic metres for a terraced house and 50 for a semi-detached or detached one, provided the work does not extend beyond the existing roof plane at the front and the materials match. Those rights are removed in conservation areas, on listed buildings and where an Article 4 direction applies, so we check your E14 address with Tower Hamlets Council before design begins. Building regulations apply either way.
We work on them constantly. loft conversion at a E14 address needs the structure confirmed by an engineer before design, and GS Renovation coordinates that as standard across Canary Wharf.
In the apartment blocks that make up most of E14, no. The roof is common structure owned by the freeholder, your lease does not include the space above the ceiling, and most blocks have no usable void in the first place. Loft conversions here belong to the older houses in the surrounding Tower Hamlets streets. Inside a flat we can still carry out structural alterations with freeholder consent.
Yes, Canary Wharf is well inside our usual patch for loft conversion, and so is most of Tower Hamlets. There is no travel surcharge for a E14 address.
