Working in Daventry
Site visits are available across Daventry (NN11). Neighbouring towns we cover include Towcester (11 miles), Northampton (12 miles), Brackley (16 miles), Market Harborough (18 miles).
For homes towards Warwickshire, Rugby is around 9 miles away. The East Midlands has plenty of inter-war and post-war semis and detached houses with room to extend, alongside Victorian terraces in the towns.
Who a porch extension suits
- Front doors that open straight into a living room
- Homes wanting better kerb appeal
- Busy hallways with no storage
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 Daventry
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.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Questions people ask about porch extensions
How long does a porch extension take to build in Daventry?
On site, typically 2 to 4 weeks once approvals are in place. Before that, allow 2–8 weeks design and approvals.
Do you cover all of Daventry?
Yes. We cover Daventry and the surrounding parts of Northamptonshire. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Daventry, 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 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 £3,800 to £14,250 including VAT, depending on size, materials and whether it includes a WC.
