Planning rules that apply in Wiltshire
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
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).
Covering Wiltshire
Towns we cover in Wiltshire include Swindon, Salisbury, Trowbridge, Chippenham, Melksham, Devizes, Warminster, Calne. 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.
What we take care of

Your questions about a porch extension in Wiltshire
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Wiltshire, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Wiltshire 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 Wiltshire?
Yes, across the whole of Wiltshire. Site visits are free and there is no obligation.
Do I need planning permission for a porch?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² (measured externally), no part is higher than 3 m, and no part is within 2 m of a boundary next to a highway. Other nations have similar but separate rules.
How much does a porch cost?
Our guide range is about £4,050 to £15,300 including VAT, depending on size, materials and whether it includes a WC.
