Landscaping- 27 Sep 2024
Simon, Danielle, Craig and Harry did a fantastic job for us on our new front, rear and side patio, new side gate and post, and new lean to. They interpreted our vision perfectly and used their experience to make great suggestions. We are delighted with the outcome. They are a friendly and courteous team; I would highly recommend them and would go to them first for any future quotes.

Greg Thomas

Extension Builder in Lewes
Welcome! My name is Greg, I’m 34 years old and I’ve been working in construction for 19 years now, I started in June 2005 at the age of 15 and started an apprenticeship in bricklaying by September that year, I was never hugely fond of bricklaying however with the precise perfectionist attitude I have It turned out I was pretty good at it! Working for a mid-size building company with great values sent me down a path of getting to experience all the trades and try my hand at them, I became very fond of carpentry and tiling but the real passion I found was being outside patios and hard landscaping, I had a rich start laying copious amounts of Brazilian black slate which any tile/slab layer will tell you is one of the hardest to lay! Given that my specialities would have to lay in the bricklaying/ slab laying and general landscaping areas with a keen eye for design and love for the environment and horticulture of the land I approach every job excited to work with you the customer to help make your dreams a reality, Every job has to be perfect for me even to the dismay of my work force when I have taken work up if not happy, and quality over quantity always. Will cover Sussex/ Hampshire/ Kent/ Surrey Please get in touch. Greg

What to ask a Lewes extension builder before hiring?

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

An extension builder in Lewes 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 Lewes 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 Lewes?

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 Lewes 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 Lewes 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.
