Extensions- 19 Jul 2021
Jitender/Tinku and his team were excellent from the first time we met. They provided us with ideas to better our layouts, helped with sourcing a number items and put us in contact with suppliers which helped us achieve more competitive prices. I was kept updated with the progress regularly and most importantly the project was completed on time and within budget. Shah Builders take real pride in their work and it shows in the finished product. We are very pleased with the outcome of the project and have recommended Shah Builders to friends and family.

Restoration & Refurbishment- 8 Jan 2021
Matt and the team at Gillfield were an absolute pleasure to deal with, right from the start and all the way to completion of the project - refurbishing a large flooded basement office.

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.

Conversions - General- 29 Jul 2015
Found John to be extremely helpful in giving ideas for problems which came up. Would Highly recommend them, they were very happy to come back and sort out a few snags even after full payment was give. When a wall was been taken down a lot of dust and mess was created as you would expect and we came home to the guys mopping the floor to try and tidy everything up! Other positives were how flexible they were with working times such as early/late on weekends and evenings in the week. Can't recommend them enough, great price and it felt like they treated the job as if it was in their home. Will use on our next project for sure.

I had a ground floor extension, patio, kitchen and first floor wet room built by Altun Construction. The work was carried out to my complete satisfaction, within the agreed budget and to a very good standard of workmanship. It did take longer that planned, partly as I had further work done and any issues were sorted by Dursun and his team I would recommend them

The job was done immediately and took just half of the day. Was very good communication between the date we contacted Johny and he gave us very good advice. He had patience to all our questions and gave us a lot of indication and options comparing with other builders. In the end, he did more jobs for me because he has a big company, so we did with him the plumbing system as well. Definitely recommend this person and his company because they did the jobs properly and very quick, no need to wait 3 weeks or even worse 1-2 months to book them.

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.

Added partition walls and a doorway to modify the entrance to our office area, creating a small meeting room. The work was completed to a good standard and at a time that suited us. Works were completed on time. The quote was 30% lower than what we paid in the end, but I think the result was worth the price.
