Extensions in and around Bridport
Postcode districts we cover around Bridport include DT6. We also work in nearby Dorchester (15 miles), Weymouth (16 miles), Poole (35 miles), Wimborne Minster (35 miles).
Just over the Somerset border, Yeovil is about 15 miles away. South West homes range from terraced streets in the cities to stone cottages and bungalows in the countryside, and conservation areas are common in historic centres.
Planning and approvals in Bridport
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.
The planning position for a specific Bridport address depends on its history and any designations, which is why we check it at the first visit.
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).
What we take care of
- Glazed, sloping or flat roof with rooflights
- Design to keep daylight in the middle of the house
- Removal of the side wall and new steelwork
- New boundary wall or raised party wall
- Party wall notice support (England and Wales)

Your questions about a side return extension in Bridport
Will my neighbours in Bridport 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.
Do you cover all of Bridport?
Yes. We cover Bridport and the surrounding parts of Dorset. Site visits are free and there is no obligation.
Do I need building regulations approval in Bridport?
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 Bridport, 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.
