Do I need planning permission in Telford?
In England a single-storey side extension can be permitted development if it is no more than 4 m high and no wider than half the width of the original house. Two-storey side extensions, and any side extension on designated land such as a conservation area, need a householder planning application.
The planning position for a specific Telford address depends on its history and any designations, which is why we check it at the first visit.
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).
What is included
- Windows, doors and finishes to match
- Planning route checked or application made
- Survey, design and street-view drawings
- New openings through the side wall
- Foundations near boundaries and any drains
- Structure, roof tied into the house
Councils often prefer side extensions to sit slightly back from the front of the house with a lower roof, so the original building still reads clearly. We design to those principles from the start to avoid redesigns.

Wolverhampton, in West Midlands, is roughly 15 miles from Telford and also on our list. The West Midlands has a large stock of 1930s and post-war semi-detached houses, which are well suited to rear, side and over-garage extensions, plus Victorian terraces in the older inner areas.

Common questions in Telford
Can I see a price before committing to anything?

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 Telford?

How much does a side extension cost?
Our guide range is about £1,700 to £3,300 per m² including VAT, depending on specification, so a standard 18 m² single-storey side extension lands around £35,500 to £46,500 in Telford.
Can I build over my driveway?
Yes, if the foundations work and you keep any parking the council requires. Drains and services under drives are common, so we check before design.
