Covering Coventry
Postcode districts we cover around Coventry include CV1, CV2, CV3, CV4, CV5, CV6. Nearby, we also take on projects in Solihull (11 miles), Shirley (13 miles), Sutton Coldfield (17 miles), Birmingham (17 miles).
Kenilworth, in Warwickshire, is roughly 5 miles from Coventry and also on our list. Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
Planning rules that apply in Coventry
In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set from 1 April 2026.
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.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Coventry
Who do I contract with in Coventry?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do you cover all of Coventry?
Yes. We cover Coventry and the surrounding parts of West Midlands. Site visits are free and there is no obligation.
Do I need building regulations approval in Coventry?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I use your drawings with another builder?
Yes. Once paid for, the drawings are yours to use for your project.
Do I need an architect?
Not necessarily. For most extensions an experienced designer or architectural technologist is enough. For listed buildings or complex sites an architect’s input can help.
