What our clients say
Ten years of extensions across Greater Manchester. Here is what homeowners and landlords think of our work.
★★★★★
"MMR completely transformed our Victorian semi in Cheadle. Rafay managed everything from the extension foundations to the final plastering. Tidy site, honest pricing, and the finish was excellent. We've already recommended them to two neighbours."
★★★★★
"We used MMR for a full loft conversion in Hazel Grove. The team were professional throughout, kept us updated at every stage, and finished on time. The quality of the joinery and plastering is outstanding. Would not hesitate to use again."
★★★★★
"Rafay and his team carried out a rear kitchen extension for us in Bramhall. From planning through to handover the whole process was smooth. They flagged a drainage issue early that saved us a lot of money down the line. Brilliant service."

Local knowledge
What is an Extension?
A home extension adds new floor space to an existing property, either at the rear, side or above. Stockport has a large stock of Victorian and Edwardian semis, particularly in Cheadle, Cheadle Hulme and Bramhall, where rear extensions are one of the most popular ways to create open-plan kitchen-dining space. Most single-storey rear extensions fall under permitted development, meaning no planning application is needed, though detached properties have a 4m limit and semis or terraces a 3m limit. Properties in conservation areas, including parts of Marple and Bramhall, require full planning permission for external alterations, so it is worth checking before you start.

Common questions
Questions about Extensions
Straight answers to the things people ask most.
How much does a building extension cost in Stockport?
A single-storey rear extension generally starts from around £25,000 in the Stockport area. Double-storey extensions and more complex builds cost more. The best way to get an accurate figure is to call Rafay on 07513058104 for a free site visit and quote.
Do you charge a call-out fee?
No. Rafay comes out, looks at the job and prices it for free. There is no trip charge and no obligation to proceed. That applies to extensions and every other service MMR offers.
Do you need planning permission for a home extension?
Not always. Most single-storey rear extensions fall under permitted development rules. Detached properties can extend up to 4m and semis or terraced houses up to 3m without a planning application. However, if your property is in a conservation area, such as parts of Marple or Bramhall, or if the extension is larger than these thresholds, you will need planning permission. MMR can advise you based on your specific property and location.
How long does an extension take?
A typical single-storey rear extension takes between 8 and 14 weeks from groundworks to completion. Larger or more complex extensions take longer. Rafay will give you a realistic programme at the quoting stage so you can plan around the build.
Are you CHAS accredited?
Yes. MMR Design & Build is CHAS accredited and CSCS registered. CHAS accreditation means our health and safety standards have been independently assessed and verified. When you hire us for Extensions, you are working with a contractor that has been audited, not just self-certified.
