Will the council need to approve it?
In England a single-storey side return infill is often permitted development if it stays within the height limits and is no wider than half the width of the original house. Conservation areas, listed buildings and flats always need an application, and the boundary wall usually brings in the Party Wall Act.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

Covering Gloucester
Our survey diary covers Gloucester, including GL1, GL2, GL3, GL4. Neighbouring towns we cover include Cheltenham (7 miles), Stroud (8 miles), Tewkesbury (9 miles), Dursley (13 miles).
Just over the Herefordshire border, Ross-on-Wye is about 15 miles away. In the South West, local stone, render and brick vary from town to town, so matching materials is a big part of designing an extension that looks right.

Side return extension questions answered
Do you cover all of Gloucester?
Yes. We cover Gloucester and the surrounding parts of Gloucestershire. Site visits are free and there is no obligation.
How long does a side return extension take to build in Gloucester?
On site, typically 10 to 14 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do I need building regulations approval in Gloucester?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does a side return extension cost?
Our guide range is about £2,140 to £3,880 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £26,500 to £34,000 at standard spec in Gloucester, more in London.
Will the kitchen be darker?
Not if the roof is designed well. A glazed roof or a line of rooflights along the boundary usually makes the room brighter than before.
