If you are looking for a caring and conscientious builder then look no further than Stephen. Not only is he on your side for your project and budget, he gets the job done with absolute attention to detail. He works incredibly hard and is not satisfied till you, the client, are happy. He has a photographic, encyclopaedic memory for all things building and structural. He, with his extensive experience, is worth more on your project than any architect plans or drawings. Not only is he damned good at what he does, he’s polite and thorough. He also has a fantastic team that he keeps a close eye on at all times. There are no loud radios or requests for coffee. His team have a fixed break/lunch, bring their own supplies and I’m embarrassed to admit, leave your house tidier and cleaner than when they arrived - even when doing excavation/structural work! I offer only one word of caution, once Stephen and team are in, you won’t want them to leave, and you will start asking him to do all those other building jobs you never knew you wanted done! You will be very fortunate if you can secure him for your project. You can complete confidence in him, his team and their work.

Restoration & Refurbishment- 28 Aug 2018
We had the very intricate loft reconfiguration done with extra big size window installation and full refurb on our recently bought Victorian end of terrace. It was a great experience all along, starting from the quantity surveyor detail level quote provision to the sign off and snagging. I was pleasantly surprised by the attention to detail with what Lux Construction delivered the works, and project manager Jonas professionalism was exceptionally high from my personal experience. Upon such a great experience I have been recommending you to all our neighbours when being asked who did such a perfect job for us. Thank you once again.

Extensions- 29 Sep 2026
I instructed ELBA (managed by Ramon) for a full property refurbishment commencing in August 2025. The sub-contracted team led by Ali abandoned the project two months past the agreed deadline, leaving the property unfinished—specifically the kitchen and bathroom. Over a three-week period, more than 40 calls and messages went unanswered. Ultimately, I had to retain and fund another contractor to bring the property to a habitable state. Three months post-completion, a wall leak emerged in the neighboring property—an issue that had never occurred prior to this refurbishment. My attempts to report this to Ramon in January 2026 were met with total avoidance. the leak recurred on September 22nd. Once again, all attempts to engage with Ramon have been ignored. I retain complete timestamped correspondence, and progress photographs.Having exhausted all standard avenues of resolution, I am currently formalizing the evidence dossier to initiate legal proceedings against ELBA and Ramon.

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.

Laura worked for me over the summer on a large dry stone retaining wall. She was a diligent worker, not put out by the heavy work of stripping out or the energy sapping heat. She showed a good level of skill when it came to laying stone and put together a strong and aesthetically pleasing wall.

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!

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.
