GS Renovation works on lofts and structures in Stratford, but E15 needs an honest answer up front. Most of the newer housing here is flats in new-build blocks and conversions, where a loft conversion is not usually possible. On the surviving Victorian terraces it very much is. We survey, then coordinate the engineer and Newham Council building control.
Flats and apartment blocks in E15
In a new-build block around the Queen Elizabeth Olympic Park, or in a converted building, the roof void does not form part of your leasehold demise. It belongs to the freeholder, which means any scheme would need freeholder consent and a lease variation before Newham Council planning was even relevant. Add the block's communal escape route, its fire compartmentation and its warranty, and an individual conversion is almost never viable. We say so rather than sell a survey.
There is still work we can do inside a flat: engineer-designed structural openings, alterations to internal walls where they carry load, and improvements to fire separation. All of it needs freeholder consent and building control, and we help you put together the information a managing agent will ask for. If the honest answer is that your building will not allow it, you will get that at the first visit.
Victorian terraces around Stratford
The older E15 streets between Stratford and West Ham Park are a different proposition. A bay-fronted terrace with a rear closet wing suits an L-shaped dormer, which uses the wing roof to buy enough floor area for a double bedroom, an en suite and a landing. A plain rear dormer is the cheaper route. Indicative London ranges for 2026 are roughly £45,000 to £65,000 for the dormer and £55,000 to £80,000 for the L shape.
Terraced houses have the smaller permitted development volume allowance, commonly cited as 40 cubic metres, and conservation area designation or an Article 4 direction removes those rights outright, so we check the address with Newham Council. The structural side is standard for these houses: steel beams spanning between the party walls onto padstones, an engineer-designed floor above them, and a protected stair route built to satisfy Part B.
- Insulation between and over rafters to Part L
- Structural steel sized by the engineer and set on padstones
- Mansard conversions where planning will not accept a dormer
- Building control inspections booked at floor, steel and completion
- Rooflight conversions where the roof line must not change
