We bought a property at auction and needed advice on redesigning and improving the space. The team gave fantastic recommendations on the new layout, energy efficient solutions and even suggestions for incorporating a swimming pool. Their knowledge, professionalism and eye for detail made the entire experience straightforward and hassle-free. We’re extremely pleased with the final result and the eco friendly options they proposed. They were dependable and supportive throughout the whole project and we wouldn’t hesitate to recommend them to others!!

Conversions - General- 18 Nov 2017
I was very lucky to find Ryan and Bill on this website! They completed my job in the time promised and I couldn't be happier with it! They were great. Nothing was too much trouble and they tidied up every evening. They were v thouthful whilst stripping out the kitchen as they would plumb washing machine in every night before they left on a temp pipe and didn't leave me without a cooker or temp fresh water tap at all! The job is finished to a high standard as they are perfectionists! I would absolutely recommend them ! On a personal level they are both v likeable and polite and like to think up suggestions and ideas for the project along the way. I will 100% be using them again .

Kitchen Fitting- 14 Jan 2019
We employed Trend Build Construction to undertake extensive refurbishment works of our kitchen and hallway that included removal of a chimney breast, plastering, underfloor heating, plumbing, kitchen re-wiring, flooring, kitchen fitting and installation of a built in cupboard. The work carried out by Alan, Teo, Julian and the rest of the team was to a very high standard and we are thrilled with the end result. Disruption from the work was inevitable; however, the guys worked hard to seal off the rest of the house from the dust and always left the house tidy. We would not hesitate to use Trend Build Construction again and would happily recommend them to others.

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

An extension builder in Hartfield 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 Hartfield 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 Hartfield?

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

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.
