Couldn't recommend Domi & Emile enough. They have great building knowledge and kept us informed and up to date throughout the whole building process. The job was finished to a high standard and they even came back free of charge to tie up a few snags a few weeks later. Great builders and a great team!

Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Carpentry- 24 Jan 2021
George came to do up our hallway. He laid flooring and installed new spindles and a handrail on our stairs too. He did a wonderful job on the whole lot and we were very happy with him. We were awkward and changed our mind on the first laminate flooring that I had picked out online, he ripped it up and started again with the new flooring we picked and it was no hassle to him. George is a lovely fella, trustworthy and professional. Would highly recommend

Bathroom Fitting- 9 Feb 2019
Alexandros did an exceptional job with our bathroom. As it was our first major renovation we were very anxious about the whole process but Alexandros made everything very easy and smooth from the beginning until the end. Alexandros has a lot of experience and he is full of ideas and good suggestions. The new bathroom looks amazing and we could not have chosen better than Alexandros. Alexandros was very helpful throughout the whole process. I would highly recommend Alexandros to anyone and we will definitely use his services in the future.

Had confirmed I would take a day off for the job. Received a text on the day at the time he was meant to come saying van had broken down and could not come. Then offered to send a friend to do the job. Waste of a day and spent morning running around buying the equipment. If the van did really break down then that’s a fair excuse. Negative experience from my end.

I met up with Peter, told him what needed doing and he provided a detailed quote within days. I handed over a set off keys and basically left him and his team to get on with it! This was a time restricted job, he purchased all the material and provided all the receipts. I returned a week later to find the job completed to the highest standard surpassing my expectations. I will definitely be working with Peter again in the future and I would highly recommend him.

Mohammed Huda and his builder were professional and quick to attend our job –– recommend! The communication was fast and professional. Mohammed provided a detailed quote (our job had to go through insurance) that is fair and transparent. The builder who came around, Jafa, was very respectful to our things. We were able to trust him from the get-go and had a peace of mind when he was working. He works incredibly hard and is methodical in his process (e.g. painting ceiling first, then walls, so to avoid splatter unevenness). They responded to our requests quickly and fixed things we weren't 100% happy with. The team finished the job ahead of time, and gave us tips for refurbishing in the future. Very happy and highly recommend!

Demolition- 24 Nov 2021
We employed A.V Structures for the building of an external wall around our property, the removal of a garage and the installation of railings and gates. Throughout the 4 week programme we could not have been happier with their work. Arrival was prompt, their pace of work displayed energy and purpose. They were mindful of us and our neighbours and made sure the area was left clean and tidy at the end of each days work.in addition the workmen were courteous and kept us fully informed. Alex, the owner of the company, kept in close contact with us to assure himself of our satisfaction. He came on site at intervals to check that all was going according to plan. We therefore felt completely confident that quality and outcomes were important to him. Employing A.V Structures was a decision we were pleased to have made. We would use them again without hesitation and recommend them highly to anyone considering similar work.
