Extensions in and around York
Postcode districts we cover around York include YO1, YO10, YO23, YO24, YO30, YO31. Nearby, we also take on projects in Selby (12 miles), Harrogate (19 miles), Ripon (24 miles), Northallerton (31 miles).
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.
What we take care of
- Single-storey extension options assessed first
- Structural survey before any upward extension
- Level thresholds and accessible layouts
- Roof designs that tie into the existing hipped or gable roof
Planning rules that apply in York
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
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.
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).
