Dormer, hip to gable and mansard loft conversions in Hackney. Trusted, professional, 30+ years' hands-on experience.
GS Renovation works across the borough of Hackney, where warehouse conversions and new-build apartments sit next to Victorian terraces around London Fields, Victoria Park and Stoke Newington. Whether a loft conversion is possible depends entirely on which you own. We give you the honest answer at survey, then build to the engineer's design under Hackney Council building control.

If you are in a converted warehouse in E8 or a purpose-built block near Shoreditch, the roof space above you is almost certainly retained by the freeholder. Converting it means acquiring the airspace and obtaining freeholder consent before a single drawing is worth commissioning, and most blocks will not entertain it. Shared escape routes, a common structure and the block insurer's position usually settle the matter. For most Hackney flats, a loft conversion is not a realistic project.
That does not leave you with nothing. In leasehold and converted properties we carry out internal structural alterations where the lease and the structure allow, remove non-original partitions with engineer-designed steel, improve fire separation between flats, and refurbish warehouse interiors properly. We would rather set that out at the first visit than let you spend months on consents that will not arrive. If your freeholder does confirm the airspace is available, the picture changes and we will look again.
Where you own a whole Victorian terrace in Clapton, Homerton or Stoke Newington, the standard options are live. A rear dormer squares off the back slope, and an L-shaped dormer wrapping over the closet wing gives enough width for a bedroom and en suite. We measure ridge height first, since roughly 2.2m to 2.4m is what makes a conversion viable without lowering ceilings, and check where the stair can land within Part K limits on rise, going and headroom.
Hackney Council has extensive conservation area coverage, which removes permitted development rights for dormers, so the 40 cubic metre allowance quoted for terraces cannot be relied on here. Building regulations apply either way: a protected stairwell to a final exit with fire doors and interlinked alarms, engineer-sized floor joists on steels bearing on padstones, and Part L insulation. Those steels land in the party wall, so you as building owner serve notice while we prepare the technical detail.
Hackney clients value GS Renovation for telling them early whether a loft is realistic at their address rather than selling a survey into a dead end. On houses we run the engineer, the steels, the fire strategy and Hackney building control as one job.

It's the second time I have hired George and he has been absolutely professional and the work he did resembles perfectly what I had in mind. Being an interior designer, I will keep hiring his team for any incoming projects.
We loved working with George and Ibrahim and would highly recommend them. They have done splendid job on our new kitchen refurb which including new flooring, moving the services, installing RSJ and preparing space for new back doors…
I am very happy to recommend George after he completed the work on my 2 bathrooms. He worked very hard to make sure everything was completed and even came on a Sunday evening to finish the work...which shows how committed he is to…
FAQ
The cost of loft conversion tracks scope far more than postcode. We price the structural work, the finishing and the Hackney Council approvals as separate lines, so you can see where the money in a E2 project in Hackney 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.
The structural element of loft conversion is usually quicker than people expect. It is the making good, decoration and sign-off at the E2 property that fill out a Hackney programme.
Quotes are free and carry no obligation. If the loft conversion figure does not work for you there is no follow-up pressure, and the E2 survey costs a Hackney homeowner nothing either way.
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 Hackney is what building control examines hardest. Insulation must satisfy Part L. GS Renovation manages the Hackney Council application and inspections for your E2 conversion.
We do, regularly. Older properties behave differently once opened up, so loft conversion at a E2 address is surveyed carefully before we commit to a method or a price in Hackney.
Rarely. In most E8, E9 and N16 blocks and warehouse conversions the roof space is retained by the freeholder, so you would need the airspace granted and formal freeholder consent before design work is worthwhile, and shared escape routes often make it impractical anyway. We will say so at survey. Whole houses in the borough are a different matter and can usually take a rear or L-shaped dormer.
