Loft Conversion- 31 Mar 2026
We recently hired Altin to do our mansard loft conversion and honestly, it was a really good experience from start to finish. He was always on time, worked really hard, and his whole team put in a lot of effort every day. Communication was easy and straightforward, which made things much less stressful for us. The project was finished on time as agreed, and we’re really happy with the quality of the work. Altin was also super helpful whenever we had questions and helped a lot with building control, which made a big difference. It’s quite a messy job (cutting through the ceiling and putting in a staircase), but they did everything they could to keep things as clean and tidy as possible, which we really appreciated. Overall, we had a great experience and are very happy with how everything turned out. I’d definitely recommend Altin to anyone thinking about a loft conversion.

Polar Build did a fantastic job on our bathroom! From planning to completion, they were professional, efficient, and tidy. They offered helpful design advice, and the quality of work—from plumbing to tiling—was top-notch. Every detail was carefully finished, and they made sure we were satisfied throughout. Highly recommend Polar Build for any bathroom project!

Conversions - General- 18 Mar 2019
Negedet and his team are friendly, knowledgeable and simply brilliant. The work estimate was a crucial factor in choosing Velvet Construction and they went out of their way to delivered it. Their work pace is incredible without compromising on quality. They arrived when they said they would, were very respectful and very tidy at the end of each day. Negedet gave important advice when we were not quite sure and accommodated changes easily with no bother. The quality of the build is excellent and the finished work looks great. They were upfront on budget and there were no hidden costs. I've already booked Velvet Construction for my new kitchen, I would recommend them to everyone!

Conversions - General- 30 Jun 2017
The project was a complete renovation of 2 bedroom period flat - adjusting internal walls, new kitchen, 2 new bathrooms, electrics, boiler, rads, new floor etc + full decoration. The Home Design & Build team were fantastic from start to finish - I'd give them 5 stars and would fully recommend. The quality of the work is outstanding - great craftsmanship and attention to detail + a very 'can-do' attitude to the bespoke elements and alterations that occurred throughout the project. The quote was clear and competitive, and the project stayed on budget aside from a few small additions to the scope which were added on at fair and transparent rates. It also stayed within the planned timescales (which is a first from my experience) and the team worked hard to complete on time. Both Lalli (who managed the project) and Mario (who led the work) were great to work with, highly capable and full of helpful and practical suggestions to the detail of the design.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!
