Extensions- 13 Apr 2024
I had a lot of work done inside the house, installing a kitchen and bathroom including the plumbing and electrics, knocking down walls and changing the layout of the rooms.The work took a lot longer than expected but was completed to a high standard. We had to wait a long time for windows which held everything up and was beyond the control of Martyn or the team.The team were professional and knowledgeable and respectful of us having to live in the house meanwhile.

Extensions- 21 Aug 2022
Rob Workman IS a master craftsman. I know it says so in writing. But now that our extensive rebuild and extensions are complete, we have seen it with our own eyes as our project unfolded. Rob took our falling down, damp, mouldy, unattractive bungalow and gave us back the keys to what more than one visitor has described as a ‘Grand Designs’ and stunning modern home that meets the highest grade of eco builds. As well as working with meticulous care & always remeasuring twice ‘just to make sure’, Rob proved himself to be good at tackling the challenges & curve balls that doing up a house is always going to throw up. Our roof, and two of the walls, proved to be insubstantial to the point of dangerous. Rob worked hard to find a cost-effective solution which met the approval of the building inspector and structural engineers. As well as Rob working on site, he brought Matt and Josh who were the epitome of polite, careful workers whose own professionalism at everything from groundwork, brickwork roofing & much else besides was a pleasure to see. Other contractors who Rob brought in - such as Simon Stadden Windows - produced great quality work to complement that of the main team. We are than pleased with the work done, with the timeliness of the work, with the price, with the tidiness of the team, and above all with the gorgeous, solid house they have left behind for us. We can recommend Rob and his team unconditionally to those looking for builders.

What to ask a Westbury extension builder before hiring?

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

An extension builder in Westbury 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 Westbury 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 Westbury?

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 Westbury extension builder’s ability to deliver a result that meets your expectations.
