Working in Highbury
Across N1C, N1, N4, N5, N7, N16, we can visit, measure and advise. We also work in nearby Holloway (1 mile), Stamford Hill (2 miles), Camden Town (2 miles), Chalk Farm (2 miles).
Waltham Abbey, in Essex, is roughly 10 miles from Highbury and also on our list. London's housing is dominated by Victorian and Edwardian terraces, many with a rear outrigger and a side return, and 1930s semis in the outer boroughs. Conservation areas are common, so the planning check comes first.
Planning and approvals in Highbury
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
What we take care of
- Roof design matched to the existing pitch and tiles
- Lead or proprietary flashings to the main wall
- Roof windows positioned for light and ventilation
- Vaulted ceilings or flat ceilings with storage above
- Insulation to current building regulations
Matching tiles is harder than it sounds. We source reclaimed or closest-match tiles where the originals are no longer made and agree samples with you before ordering.
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Pitched roof extension questions answered
Who do I contract with for a pitched roof extension in Highbury?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do you cover all of Highbury?
Yes. We cover Highbury and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Do I need building regulations approval in Highbury?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I have a vaulted ceiling?
Yes. A vaulted ceiling with roof windows is one of the main reasons to choose a pitched roof. It needs insulation between and under the rafters to meet the building regulations.
How much does a pitched roof extension cost?
Our guide range is about £2,400 to £4,550 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
