Extensions- 17 Nov 2023
Hired Rob to build a large 2 storey wrap around to a 3 bed detached house and a full new roof over the whole thing. Rob worked directly on the project along with Paul and together make a great team. From the offset Rob was confident in how he would approach each element of the job and was proactive in planning ahead and ensuring he had plant and materials on site when needed. Rob called in other trades when required such as plumbing, electrical and a firm to pump and lay concrete flooring. He involved me as much as needed when decisions were to be made throughout the job but was always busy and kept a high pace of progress all the way through. Communication with Rob was good throughout the project both with regards to finances and timescales. This was key so we could tackle and overcome unforseen circumstances together. Ultimately Rob, and Paul, have left me with an amazing house I love coming home to.

Extensions- 3 Jan 2024
Quoted us 85k for a 14 week job for a 1 storey extension. We have extra work done sure but this has been inflated. He's had over 105k from us, now at 34 weeks. Asking for 4k more. Didn't sort building reg certificate I had to. Didn't pay tradesmen work for months, went on holiday 3 times during (Jamaica, Egypt and God knows where). Won't confirm who the warranty lies with. Paid him £3k extra for a patio base which was done as a bodge job, ended up having to rip it up and got it done by someone else for 1k. He used waterproof membrane which created a swamp. Got lots of photographs of the promised 10cm hardcore being 1cm. Do not trust, contact me and I will show you all you need to avoid him. Moving towards court...

Bricklaying- 24 May 2025
We had a curved wall built for our driveway by PLC Developments. They came out the day after our enquiry, provided a quote the same day, and started work that week. The job was completed within a few days, and the standard of work was excellent. We already have a second job lined up with them. Like others, we were initially unsure about using a new business without reviews, but we’re really glad we did. These guys are very skilled at what they do, respectful of your property, and keep the work area incredibly clean throughout. The quality of their workmanship is fantastic, and the pricing was very reasonable. We wouldn’t hesitate to use them again in future.
