Local to Kirkby
Our survey diary covers Kirkby, including L9, L10, L11, L31, L32, L33. Neighbouring towns we cover include Maghull (3 miles), Litherland (4 miles), Prescot (5 miles), Bootle (5 miles).
Ormskirk, in Lancashire, is roughly 6 miles from Kirkby and also on our list. The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.
Planning rules that apply in Kirkby
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.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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 should I budget for a porch extension in Kirkby?
Labour and material costs vary across the UK, so for Kirkby we use our North West England factor (×0.95). The ranges include VAT and exclude design, structural and council fees.

Who a porch extension suits
- Homes wanting better kerb appeal
- Busy hallways with no storage
- Front doors that open straight into a living room
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.

Porch extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Kirkby, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Kirkby?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does a porch extension take to build in Kirkby?
On site, typically 2 to 4 weeks once approvals are in place. Before that, allow 2–8 weeks design and approvals.
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.
