Landscaping- 23 Sep 2025
We very recently had our front driveway and back garden landscaped, including a bespoke garden room and garage conversion, completed all in the space of 10 weeks, and we absolutely love what has been done by S6 Designs. Sam, Joe and Reece worked so hard, even with such high temperatures this summer and were very punctual, always tidy and respectful of our property, and came up with lots of good ideas which we grateful for. If you want a good team of workers for your project, we can highly recommend S6 Designs, they were fantastic from start to finish, you will not be disappointed.

What to ask a Boreham extension builder before hiring?

Before hiring an extension builder in Boreham or extension building company in Boreham, 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 Boreham?

An extension builder in Boreham 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 Boreham 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 Boreham?

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 Boreham 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 Boreham 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.
