Restoration & Refurbishment- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Extensions- 23 Jan 2023
Monika, Mario and the team were excellent! Finished the job to a very high standard. Monika was all over the details and Mario was highly skilled and just got things done. Despite the project overrunning by a month or so (really not that bad vs target), we can not wait to work on another project with Monika again.

Extensions- 23 Aug 2023
On schedule and to budget, Ibrahim and his team from Triada Building Ltd delivered a very high standard on this project. Despite poor weather (Summer of 2023) and some issues with 3rd party contractors, access for concrete pour, skip delivery etc. his team worked each stage of the project to plan keeping me informed and showing great level of craftsmanship. I was after a simple workshop build that would compliment our house and he did not try to over sell options I wasn't interested in. Very happy with the result, and would recommend. Thank you.

Landscaping- 18 May 2021
Joe was professional and responsive for my posted job to do fencing and wood trim repairs. He was able to provide a quote quickly and did the work in quick fashion. I wasn't quite sure what was feasible, but Joe was able to provide good guidance on what could be done for the repairs. The quality of the workmanship seems to be high, and I am pleased with the result. I would definitely recommend Joe for this type of work.

Loft Conversion- 1 Aug 2025
Sami completed our loft conversion to a high standard, on time and within the agreed budget. He was respectful, supportive, and very knowledgeable. He offered helpful input and practical suggestions throughout the project. When I came up with ambitious design ideas that would have cost a fortune, he provided honest, pragmatic advice and suggested smart, cost-effective alternatives that saved us a lot of money. He communicated clearly, was easy to work with, and kept everything running smoothly. He also recommended trusted tradespeople when needed, all of whom did excellent work. In addition to the loft, Sami and his team completed other jobs around the house with the same high standard and care. I wouldn’t hesitate to recommend him — reliable, skilled, and genuinely committed to quality. A fantastic builder who takes pride in his work and delivers results you can trust. We’re absolutely delighted with everything he’s done.

Extensions- 20 Nov 2025
I recently had a rear extension done on my 1930s house, along with a new kitchen, upstairs bathroom, and downstairs shower room, and I honestly couldn’t be happier with the whole experience. Omer came out to view the property just before completion and kept in touch so he could start work the moment we got the keys, which was brilliant for us! From day one, his communication was spot on. He explained everything clearly, set out exactly what was included in the quote, and made sure we understood the plan so there were no grey areas or unexpected surprises which is everyone’s worst nightmare during a reno!! The quality and speed of the work were exactly what we hoped for. The team often worked weekends and late evenings to keep things moving. Omer was always at the end of the phone if we needed anything, and he’s genuinely a lovely person who made the process far less stressful with his humour. I’ll definitely be using him again.
