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.

Extensions- 21 Jul 2025
I recently hired AK construction to build an extension on my home, and I am beyond impressed with their work ethic, flexibility, and outstanding customer service. The extension was built to the highest standard—flawless craftsmanship, attention to detail, and seamless integration with my existing home. The team was punctual, tidy, and respectful throughout the project. What really stood out was their willingness to help, even beyond the contracted work. When I had some DIY tasks, they offered advice, lent me tools, and even stepped in to assist where they could—despite not being obligated to do so. Their kindness and professionalism didn’t waver, even when I declined additional quotes for other work. They stuck to the timeline and budget with no surprises. Communication was excellent, and they treated my home with care as if it were their own. I can’t recommend Ali and AK Construction enough—they’re trustworthy, skilled, and genuinely care about their clients.

Extensions- 2 Apr 2026
Very happy with the Dining Room Extension, Utility Room Extension, Kitchen refit and Patio. Andrew, Steve, Kevin, Mick and Jake did a fantastic job in a professional way. They were thoughtful and considerate in all the activities. I have no hesitation in recommending Oliver General Builders and will have them back for the next phase of building works. We got to know the builders quite well over the project and a little bit sad that it has now finished. We received some great recommendations on decisions we needed to make and they were flexible with our changing requests and patient while we decided on tiles, etc. The Electricians as well as the Plumber were also very good in the level of expertise.

Groundwork & Foundations- 27 May 2026
Rich was v knowledgeable and priced the job from photo's and a video. Kept his word and turned up on the agreed day. He got to work straight away, broke up the original pipework and installed a new set of plastic pipes. He created a new connection for a vertical stack and improved what was there. Rich was finished within 2 days and drains are definitely working better since he did the work. I would like him to come back and finish the stack. I thoroughly recommend Rich if you're looking for a reliable and competent builder.

I asked Jamie and his team to help me erect my garden room this autumn and I could not be happier with the result. Jamie understood the brief immediately, was clear about pricing and responsive via text. He and his crew turned up on time, worked hard to offload and build the structure and were good humoured and polite to boot. They clearly take pride in their work and I wouldn't hesitate to use them again.

Landscaping- 26 Apr 2023
CBK Design & Build did an excellent job of transforming my derelict deck into a bright usable patio. I am very pleased with the outcome… and so are the neighbours it would appear. They excelled in all aspects of the job 1. The Quote: Everything was clearly indicated and was very competitive. Any adjustments were made promptly and revised quote was immediately available. All queries were instantly answered and advice was also valuable. 2. The Work: Work started at indicated time on the agreed day. They were very quick and it was probably the worst week weather wise for this job. But they carried on despite that. The work was completed within the estimated time, with little or no wastage of material and to a high standard. All unexpected issues were quickly resolved and creatively too. Poor quality work from previous tradesmen was also rectified for no extra. 3. Attitude: Both Mehmet and Serkan worked with smiles on their faces through some of the worst weather, and all other unexpected issues with no complaints at all. Very positive work ethics. Extra points for doing their best to not upset or intrude into my special needs child’s space. They even used toilets at local gas station (even though we were ok with them using our facilities) to that effect. They are more like friends of the family now, and will definitely use them again. Thank you MyBuilder.com for a great tradesman.
