The 4 Key Stages of Your Extension Project

  • 1. Consultation & Feasibility: We start by understanding your vision and inspecting the property to confirm what’s possible based on layout, structure, and planning rules.
  • 2. Design & Planning: Our architects create detailed designs and, if required, we manage the planning permission or permitted development paperwork with the local Council.
  • 3. Construction Phase: All groundwork, structural work, roofing, and internal finishes are carried out by our experienced team, on time and on budget.
  • 4. Final Sign-Off & Handover: Once the work is complete, we conduct a final walkthrough, ensure building control sign-off, and hand over a finished space that’s clean, safe, and ready to enjoy.

A Commitment to Craftsmanship and Client Satisfaction

Every extension we build is a reflection of our reputation. That’s why MRJ Extensions never cuts corners or rushes through stages. From the foundations to the finishes, our tradespeople apply the highest standards of workmanship and care. We utilise high-quality materials, adhere to best practices, and conduct rigorous inspections at every stage.

We measure success not only by the build quality but by the satisfaction of our clients. That’s why many of our new projects come through referrals or returning customers.

Do I need planning permission for a house extension in the UK?

Most small extensions fall under permitted development rights, meaning you may not need full planning permission. Larger projects or those in conservation areas will usually require approval from your local council.

What are permitted development rights for extensions?

Permitted development rights allow you to extend your home without applying for planning permission, provided certain size and height limits are met. Always check with your local planning authority to confirm before starting work.

How much does a house extension cost in the UK?

On average, a single-storey extension costs between £1,500–£2,500 per square metre. Prices vary depending on location, design, and the complexity of the build.

How long does a house extension take to build?

A straightforward single-storey extension may take 10–12 weeks to complete. More complex or multi-storey builds could take 4–6 months.

Can I live in my house while the extension is being built?

Yes, most people stay in their homes during the build, although there may be some disruption. Builders will often section off areas to keep the rest of the house habitable.
