Latest review:
★★★★★ Highly Recommended! I had an existing 3-bedroom rundown property and contacted multiple builders before meeting Director Mr. Q Nawaz. From our first meeting, I was impressed by his ideas and the fact that Grand Designs could provide all services in-house. Initially, I proceeded only with the planning application to see if what he promised was possible—and YES, he delivered! My application was approved as he assured me. Seeing this success, I entrusted them with the entire construction project, and Grand Designs completed it within just 6 months, despite the challenges of COVID-19. Not only did they build my project, but they also added significant value to the development. I’m proud to have worked with them, and their exceptional work on my St Albans development is now featured in their portfolio. Within one year, the value of my property increased by £500,000—a testament to their expertise! Extremely professional, highly skilled, and very reasonably priced. You don’t need to go anywhere else—Grand Designs is the complete package!

Can’t recommend Alex highly enough! He built wardrobes into our attic eaves, altered some stairs, and fitted our new wooden hallway flooring, all to an exceptional standard and at a very reasonable price. He was professional, tidy, efficient and consulted me every step of the way to ensure the finished design was exactly what I was after. I’ve already asked him about doing some future jobs I was that impressed.

What to ask a Wimbledon extension builder before hiring?

Before hiring an extension builder in Wimbledon or extension building company in Wimbledon, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Wimbledon?

An extension builder in Wimbledon should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Wimbledon extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Wimbledon?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Wimbledon extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Wimbledon extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
