Extensions in and around Westhoughton
We cover Westhoughton and the postcode districts BL5, M46. We also work in nearby Atherton (2 miles), Hindley (3 miles), Tyldesley (3 miles), Leigh (4 miles).
Just over the Merseyside border, Golborne is about 6 miles away. Across the North West, terraced houses with small rear yards suit compact rear and side return extensions, while suburban semis have room for more.
What is included
- Front door, glazing and electrics
- Brick, render or oak frame walls
- Tiled, slate or flat roof
- Planning check against the porch limits
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
Planning rules that apply in Westhoughton
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.
The planning position for a specific Westhoughton 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).
How much does a porch extension cost in Westhoughton?
