Local to Huntingdon
Postcode districts we cover around Huntingdon include PE28, PE29. Nearby, we also take on projects in St Neots (9 miles), Cambridge (16 miles), Peterborough (17 miles), March (19 miles).
The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.
Included in a typical project
- Party wall notice support (England and Wales)
- Survey of the outrigger, boundary wall and drainage
- Kitchen-ready shell or full finish
- Design to keep daylight in the middle of the house
- New boundary wall or raised party wall
Light is the design problem. A side return can make the middle of the house darker if the roof is solid, so we model the daylight and usually recommend a glazed slope or a run of rooflights along the boundary edge.
Do I need planning permission in Huntingdon?
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.
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).

Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Common questions in Huntingdon
How long does a side return extension take to build in Huntingdon?
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 Huntingdon?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will my neighbours in Huntingdon be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How much does a side return extension cost?
Our guide range is about £2,230 to £4,030 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £27,500 to £35,000 at standard spec in Huntingdon, more in London.
Do side return extensions need planning permission?
In England many single-storey side returns fit within permitted development if they stay within the height limits and are no wider than half the width of the original house. Conservation areas, listed buildings and flats need an application. Other UK nations have their own rules, which we check.
