Dormer, hip to gable and mansard loft conversions in Wapping. Trusted, professional, 30+ years' hands-on experience.
GS Renovation works throughout Wapping, where the housing is mostly historic warehouse conversions and newer riverside blocks. Loft conversions are not usually possible in that stock, for reasons of ownership, listing and fire strategy. We say so early and concentrate on the structural and refurbishment work these buildings do allow.

Wapping's converted warehouses are frequently listed or sit within Tower Hamlets conservation areas covering the riverside, and the roofs, along with the brick elevations and window openings, are exactly the fabric that protection covers. Alterations at roof level would need planning permission and listed building consent, and there is rarely a case for them. The roof is also common structure owned by the freeholder, and no residential lease normally includes the space above a top-floor ceiling.
Even where a void exists, the fire strategy of a large converted block is designed as one system, with protected corridors and stairs serving every flat. Adding habitable space at roof level rewrites that under Part B and touches parts of the building you do not control. Between the lease, the listing and the escape route, a loft conversion in a Wapping warehouse is not a realistic project, and we would rather explain why than take a deposit for drawings.
These apartments have real potential inside their own footprint. Warehouse conversions often have height, exposed structure and awkward internal walls put in during the original conversion, and taking one out onto a steel beam sized by an engineer can rework the whole plan. Kitchen and bathroom rebuilds, new services and full refurbishment are all straightforward for us, working around the constraints of a listed building where they apply.
Every job here needs the freeholder's licence to alter, and often listed building consent for internal changes, with Tower Hamlets Council building control inspecting structure and fire separation. Managing agents want method statements, agreed working hours, lift and common-part protection and proof of insurance before anyone starts, and access down narrow riverside streets has to be planned. We handle that side as part of the project rather than leaving it on your desk.
Wapping owners choose GS Renovation because we are frank about what a listed riverside block will not allow, then deliver strongly on what it will: structural alterations, engineer-designed steel, full flat refurbishment and Tower Hamlets Council building control.

FAQ
The cost of loft conversion tracks scope far more than postcode. We price the structural work, the finishing and the Tower Hamlets Council approvals as separate lines, so you can see where the money in a E1 project in Wapping actually goes. 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.
We do not run loft conversion across several sites at once. The team on your E1 project stays on it until the Wapping work is finished, which is what makes the programme predictable.
Communication is what most builders get wrong. You get a weekly update on the E1 loft conversion project, and if something changes on the Wapping job you hear it from us first.
All the ones that matter structurally. New floor steels are sized by an engineer, the staircase must meet Part K, and Part B requires a protected escape route with interlinked alarms, which on a third storey in Wapping is what building control examines hardest. Insulation must satisfy Part L. GS Renovation manages the Tower Hamlets Council application and inspections for your E1 conversion.
They are our core work. For loft conversion we survey what is genuinely there at the E1 property, because assumptions are what turn a fixed Wapping price into a variable one.
Three reasons usually apply at once. The roof is common structure owned by the freeholder and is not in your lease; the building is often listed or in a conservation area, so roof alterations need consent that is rarely given; and the block's fire escape strategy under Part B covers the whole building. Internal structural alterations and refurbishment are a different matter, and those we carry out regularly.
Wapping sits inside our normal working area, and we are usually on another Tower Hamlets site nearby. That often means a E1 survey for loft conversion can happen quickly.
