Extensions in and around York
Our survey diary covers York, including YO1, YO10, YO23, YO24, YO30, YO31. We also work in nearby Selby (12 miles), Harrogate (19 miles), Ripon (24 miles), Northallerton (31 miles).
Just over the East Riding of Yorkshire border, Goole is about 19 miles away. Yorkshire and the Humber combines stone-built terraces in the Pennine towns with brick semis and newer estates elsewhere, so materials and roof details need matching with care.
Included in a typical project
- New or upgraded foundations
- Insulated walls and roof to current regulations
- Opening widened into the house if wanted
- Trial holes to check the existing foundations
- Glazing and doors to suit the new room
Will the council need to approve it?
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.
The planning position for a specific York address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions people ask about conservatory replacements
Do you cover all of York?
Yes. We cover York and the surrounding parts of North Yorkshire. Site visits are free and there is no obligation.
Who do I contract with for a conservatory replacement in York?
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.
How long does a conservatory replacement take to build in York?
On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Does replacing a conservatory need planning permission?
A solid replacement is treated as a new extension, so it must meet the permitted development limits or get planning permission, and it always needs building regulations approval.
Is it worth replacing a conservatory with an extension?
If the conservatory is unusable for much of the year, usually yes. A solid extension gives a heated room that counts as proper living space. Our guide range is about £1,740 to £3,290 per m² including VAT, including removal.
