We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

Danny and the team (Scott, Darren, Dayne, Dennis) were fantastic, consistently working to find more effective, lower cost solutions. We enjoyed working with him so much we then took on a significant amount more work with him, that involved a full fit out of a fitness studio. Danny has a wide network of individuals with many areas of expertise he can call on when necessary. In a couple of the really difficult moments of the project Danny went over and above what you would expect. We were delighted with the work and will be recommending him going forwards - although I’m sure everyone wants his time!

I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.

Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

I recently had extensive work completed in my flat by Vas, and I couldn’t be happier with the result. The service was excellent from start to finish. Not only was the quality of the work consistently high, but the whole experience was smooth and stress-free. What really stood out was Vas’s level of skill and versatility. Every aspect of the project was handled with care and professionalism — from plumbing and new water heating pipes, to new electrics, installing a new kitchen, laying a beautiful wooden floor, renovating the bathroom, and even replacing doors with a sliding door system. Each element was completed to a very high standard. On top of that, Vas was friendly, proactive, and easy to communicate with throughout. Nothing ever felt like too much trouble, and it was clear he takes real pride in delivering great results. It was genuinely a pleasure to deal with Vas, and I would highly recommend his services to anyone looking for reliable, high-quality work. Thank you again!

Big refurb of 1650 sq ft flat, plus building 2 additional ensuites. Initial quote seemed reasonable but then once in, costs started to rise exponentially. Some work was done well, like the building component and flooring, but finishing was poor. Painting, particularly of internal doors, was done poorly, without removal of fittings first, so lots of overpainting and insufficient prep and coats. Regrouting and redecoration of front and rear patios was done poorly, with weeds already poking through. There was damage to existing bathtubs and WCs by not protecting surfaces and pouring waste materials down the pan. Everything was an argument with constant demands for more money e.g. front door only painted one side as the other side not included under "paint door". Lots of "snagging" - I only have manual on/off control of heating and hot water as "smart" thermostat won't connect, there are odd water pressures through some fixings...and now there's a leak under one of the WCs...

We struggled to get anyone interested in our refurbishment project originally, Mark answered an ad for a small part of the job and ended up being able to take on the whole thing thankfully. Our project was to completely strip out a 1960's maisonette flat, install internal insulation which involved extensive battening of all the external walls, new plasterboarding & plastering finishes to walls and ceilings, tiling and a completely new bathroom and kitchen install. To complicate things further, as enthusiastic DIY-ers we wanted to do lots of works ourselves as well and few builders would have worked alongside novices as well as Mark did. He was always happy to give advice or take over works when we realised they were beyond our skills or time ;-) Our project was constantly evolving and challenging - as we discovered hidden rotting floor joists and the joys of 60's engineering - door lintels - who needs those?! Mark was always there to help us problem solve and get the job done professionally and to high standards and this was all done throughout the challenging last year of lockdowns etc. Without hesitation we'd recommend Mark and his team. He was always reliable, flexible as the project developed and had excellent attention to detail and we couldn't have completed our project without him. Thank you Mark!

Alex and his team did an amazing job. We hired them for a simple garden renovation project, but then as the job was going ahead and as they were extremely knowledgable, we decided to redesign the whole garden. They made the foundation for the rear extension, they disposed the old shed and decking, laid the new patio at the end of the garden and built a garden house with a toilet and kitchen. They also laid the rear patio (attached to the property) and built a covered outdoor area with a bbq and wood fired oven. It was a very big project and we are very happy with the outcome. Such an amazing transformation and we couldn’t have been more lucky in choosing A.V Structures. Very highly recommended.
