Covering Highbury
Our coverage around Highbury (N5) also includes Islington (1 miles to the south) and Holloway.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
What does a kitchen extension involve?
We design the room and the kitchen together, so the island, sink and appliances line up with the structure rather than fighting it. You can use your own kitchen supplier or have us supply and fit one. Either way we co-ordinate the trades so the room is finished in one sequence.
- Combined building and kitchen layout design
- Planning or permitted development check
- Tiling, flooring and decoration-ready finish

Planning and building rules in Highbury
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.
What can affect a kitchen extension?
- Islands with sinks or hobs need drainage and power routed in the slab.
- Underfloor heating suits large kitchen-diners with glazed walls.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
