Convert or Construct a Beautiful Basement…

Here at Basement Builder, we are an approachable, friendly team and as general manager, I take personal pride in ensuring that we serve you to the highest standard for the duration of your project. I am personally available to discuss your project in our offices where we can discuss your project in depth. Of course, you can email or call myself, or one of the team at any time too. We look forward to meeting you and I’ve been told I make a great cup of coffee. So contact us now to kickstart your project.

ANDY WALKER, General Manager



We always have different types of basement construction projects being undertaken at the same time, including retrofit basements, basement excavations, basement digouts, basement extensions, basement underpinning, and basement conversions.


Have an online chat with us to discuss your specific requirements.


We can transform your home for less than you imagined.




Why We Are Different

Well that is easy: We are Engineer-led. This means that every Basement Builder project is overseen by a qualified structural engineer from the very first design chats, to the last wipe-down from the clean up team. This offers various benefits not least of which is a reduction in cost.

We don’t have to outsource any stages of the projects we undertake as everything is done in-house. Architects, Structural Engineers, Surveyors, Legal Advice and even our very own Subject Matter Expert team for radio and TV interviews – all operate from our Head Office.

A further benefit from having everything in-house is speed – it is a lot easier to call across an office to get results, than have to wait on hold for answers.
