Tower Hamlets is a borough of two halves for loft work: the warehouse conversions and riverside apartments of E1 and E14, where a conversion is usually not possible, and the Victorian terraces of E2 and E3 near Victoria Park, where it often is. GS Renovation tells you which side your property falls on.
Warehouse conversions and new-build apartments in E1 and E14
Around the Docklands and Canary Wharf, most homes are flats. The roof, the external envelope and the structure are held by the freeholder, so a leaseholder has nothing to convert, and permitted development rights do not extend to flats. Even where a penthouse lease includes roof space, you would need a licence to alter, freeholder consent and a full planning application to Tower Hamlets Council, plus listed building consent on a listed former industrial building.
That is the honest position and it does not change with persistence. What we do carry out in these buildings is internal structural work: forming openings, installing engineer-designed steel where a wall proves load bearing, reworking mezzanines within an existing volume, improving acoustic separation and full refurbishment of a shell. All of it sits within the lease, with landlord consent and building control approval obtained first.
Terraced houses in E2 and E3
North and east of the financial district the stock changes. The Victorian terraces around Bethnal Green and Bow are ordinary houses with main roofs and, in many cases, rear closet wings, and they take a loft conversion in the usual way. An L-shaped dormer over the wing runs to an indicative £55,000 to £80,000 on 2026 London ranges; a straight rear dormer is nearer £45,000 to £65,000. Ridge height of about 2.2m to 2.4m is checked before anything else.
Tower Hamlets Council has extensive conservation area coverage in these older districts, and permitted development for roof extensions does not survive designation, so the address has to be checked rather than assumed. Building regulations apply either way: a protected stair route with fire doors and interlinked alarms, a compliant stair under Part K, insulation under Part L, and a new floor on engineer-designed steels bearing into the party walls, which triggers notices to both neighbours.
