Our extension service is customer-centric, designing and building to bespoke requirements. Features such as wall finishes, brick type, flooring and lighting can be customised.

We'll work with any plans you have already drawn up, or will help you in creating new drawings for planning permission and building regulations.


We only use professional and trustworthy tradesmen as we understand the skills and experience required for house extensions. In addition to this, we supervise each stage of the project.


Because we are so confident in our work, all of our extensions (timber or brick) come with a 10-year workmanship warranty for peace of mind

Peace of Mind

One of the most common issues for homeowners starting an extension is getting transparent and fixed prices. We've heard many stories of obfuscatory quotes and pricing, leading to surprising extras after the works start. To solve this, we provide detailed quotes, breaking down each aspect of the build to help you make informed decisions and budgets..

To improve our customer experience, we only accept payments in stages, where you would only pay once our extension team has progressed to certain stages of the build. We only ask for a 10% deposit to get started.

If you require finance, we have several financing options available to you (including 0% interest finance), which are tailored according to certain credit checks.

Why choose a brick & block extension?

Brick and block extensions are made to last.


 Its familiarity with builders and modern building methods makes the build process transparent and flexible, being "tried and tested" over the years. 

It may be a requirement for you when considering insurance policies and when acquiring planning permission as they are built to meet modern building standards.

Apart from its excellent structural strength, the bricks and block lack thermal efficiency, which can be solved to an extent with modern insulation.

As an architectural firm, we are always finding new ways to innovate the construction industry with modern technology and design. which can be implemented into new brick and block extensions.

We'd love to learn more about your project and discuss the various options available to you. 


Fully insulated with mineral wool cavity insulation (which can be upgraded to PIR upon request) and double glazing.

10% Deposit and financing

To get started, we ask for a deposit of only 10% before any work begins, giving you peace of mind and assurance as the project progresses.

Fantastic service, everything was on time and Michael was so helpful in making changes to the plans when the building control officer asked. We are really pleased with the extension and are enjoying this space very much. The builders you recommended did an excellent job, even with the delivery problems cause by lockdown, thank you for your hard work, we've recommended you to all our friends!
