Local to Reading
We cover Reading and the postcode districts RG1, RG2, RG4, RG5, RG6, RG30. Neighbouring towns we cover include Earley (3 miles), Wokingham (7 miles), Crowthorne (10 miles), Bracknell (10 miles).
Just over the Oxfordshire border, Henley-on-Thames is about 6 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
Planning rules that apply in Reading
In England a two-storey rear extension is permitted development only if it projects no more than 3 m from the original rear wall, sits at least 7 m from the rear boundary, matches the roof pitch and uses obscure, non-opening side windows upstairs. Most two-storey extensions therefore go through a householder planning application, which costs £548 from 1 April 2026 and normally takes about 8 weeks.
The planning position for a specific Reading address depends on its history and any designations, which is why we check it at the first visit.
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).

Your questions about a bedroom extension in Reading
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Reading, 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 you cover all of Reading?
Yes. We cover Reading and the surrounding parts of Berkshire. Site visits are free and there is no obligation.
Who do I contract with for a bedroom extension in Reading?
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.
Can I add a ground-floor bedroom for a relative?
Yes. A ground-floor bedroom with an accessible shower room is a common request. If it will be lived in as a self-contained home, planning treats it differently, so tell us how it will be used.
Will a new bedroom need planning permission?
Upstairs additions usually do. Ground-floor rooms may fall within permitted development, depending on size and position.
