Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.

Conversions - General- 28 Jan 2025
We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Restoration & Refurbishment- 16 May 2021
TLC have completed the first phase of the project which has involved a complete renovation and upgrade of the kitchen, bathroom, and rear garden area. A new contemporary staircase has also been fitted. The work has been completed well ahead of schedule, and this is testament to the planning and coordination skills provided by TLC. All of the work has been completed to a very high standard, and a great deal of care has been taken to ensure the minimum disruption to the local residents. We are extremely grateful for the advice and support provided to us leading up to the restoration work and whilst the restoration was underway, and we are absolutely delighted with the final results. Our house has been transformed into a contemporary family home. Many thanks to Bradley, Paul, and the rest of the team at TLC.

Conversions - General- 24 Apr 2026
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!

Martin undertook a comprehensive renovation of my entire house, incorporating rear and side extensions, a loft conversion, and a rear pod addition. The project involved stripping the property back to its bare walls, reconfiguring room layouts, and installing entirely new bathrooms and kitchen facilities. Additionally, Martin oversaw the revitalisation of the garden area. Martin's professionalism and meticulous attention to detail were exemplary throughout the project. I am exceptionally pleased with the outcome of the work. This is not my first collaboration with Martin; I previously engaged his services for a complete house renovation in 2021.
