Hard Flooring- 7 Sep 2026
I chose Chester for a kitchen and solid-wood flooring project costing around £30,000 because of his MyBuilder reviews, portfolio and experience. I now regret that decision. The problems were not minor snagging. The floor was left with gaps, opening joints, movement, creaking, hollow areas, uneven sections and damaged boards. The kitchen had alignment, fixing and finishing defects. Despite outstanding work, Chester pressed for full payment, referred to his mortgage and bills, appealed to trust and described himself as a “man of my word”, promising to return and resolve the issues. I paid in full on that basis. He later accepted that kitchen adjustments were needed and that some hollow flooring resulted from failure of the bond to the subfloor. However, his proposed remedies did not address all documented defects. Nearly a year later, the problems remain unresolved and I now have to pursue a court claim. Based on my experience, I found Chester unreliable and would not recommend him.

Bathroom Fitting- 8 Jan 2025
Venice construction did an excellent job installing a new shower cubicle in our bathroom, removing the bath and completely re tiling 3 walls. Veselin is extremely competent , pleasant and very hard working. I was astonished by his ability to restore the toilet every night so that we did not have to come downstairs. I am delighted with our new bathroom and the quality of the workmanship. Many, many thanks.

John from His & Hers construction did a very good job on our rear patio. It needed two sections of older, large porcelain tiles taking up and then new tiles putting down to match in with the rest of the patio.

Extensions- 15 Apr 2021
So delighted with the finished room, Jay had some great ideas and could visualise how it would look, which exceeded my expectations. Jay and Rhys are both highly skilled and very good at what they do, in particular the plastering and finished render looks fantastic. These works have transformed the outside area for me and with the patio laid to a high specification too I can’t wait to start using the garden again. Jay added steps and a low level wall that I hadn’t considered for the path and patio and this was so great to see as I hadn’t anticipated these elements looking so good. Thank you Jay and Rhys, really pleased with how it all came together. (I have also asked for some further works to be done based on my experience so far)

Conversions - General- 27 Apr 2019
Craig, Bob and Timmy of HD Design and Build have been an absolute credit to the building trade throughout our project. With a young family still living in the house, their professionalism, punctuality, cleanliness, advice and attention to detail meant they kept disruption and intrusion into the rest of the home to a minimum and we were able to continue life without too much disruption. I have a multitude of photos of the build throughout which show the excellent standard that they worked to every day which can be supplied on request. Craig offered objective advice based on experience throughout and although he clearly always strives for perfection, was never pushy for us to make a decision to use a high end product over something that was more affordable or suitable. Our newly laid herringbone parquet oak floor is the talk of the street and is a testament to their skill and attention to detail. The finished rooms we have now far exceed our expectations of design and quality and that is largely down to Craig's advice and the experience and skill of him and his team. Craig was also instrumental in keeping me calm in many situations when dealing with suppliers and offered sound advice without judgement. I would recommend HD Design & Build to everyone with the belief that they will make your designs come to life and then some!

Conversions - General- 2 Sep 2026
We hired Rob to complete 6 items at an agreed fixed price, with the work expected to take 4 days. Day 1 went well, but from Day 2 the situation deteriorated. He made snide comments and shouted to himself, used our garden tools without permission, and broke items without informing us, which appeared to have been hidden. By Day 3, his attitude became dismissive and volatile, leaving us uncomfortable at home. We sent messages outlining our expectations, but he then demanded additional money and disputed what had originally been agreed. By Day 4, we had to involve the police to escort him from the property after he threatened to smash down a wall he had built the previous day. We paid for the work completed, but he still demanded a further 25% despite no progress. A real shame, as he initially seemed genuinely nice. Unfortunately, poor communication and overestimating his ability to complete the job within the agreed timeframe resulted in the work being left incomplete.

Bathroom Fitting- 14 Oct 2026
Darren ensured me that the works could be completed in five days. This turned into a 2.5 week project. Not because there were problems that occurred along the way, but I feel that as he was actually committed to other jobs, my project was not a priority. When they were removing the tiles etc, the extreme removal dislodged the pipe for my bathroom toilet and caused a leak which not only flooded down into my hallway and into my light fitting which I had to replace but also caused damage to my ceiling. The towel rail which replaced a radiator, came away from the wall as it was not securely fitted and water gushed onto the newly laid floor. The shower runs scalding hot or freezing cold. It cannot be used (it has been plumbed incorrectly). When trying to contact him to ascertain when he will be attending to rectify the works, of course, I am not receiving any communication, via whatsapp, text or email. Would I recommend him? Not at all on the experience that I have had.
