Extensions- 6 Aug 2020
I’ve lost count of how many times we’ve said how lucky we were that we chose Bryan and his team to build our kitchen extension. The team went above and beyond to ensure as little disruption as possible, as we remained living at home whilst the work took place. During this difficult time, Bryan did everything possible to source the materials required to finish our build before our baby arrived and some how he managed it! His team were really friendly and the family miss having them around. They always tidied up after themselves before leaving too. What we thought was going to be a stressful time was in-fact the opposite. Bryan managed the whole process, kept us updated throughout and made sure the build remained on budget. The level of finish is of the highest standard, better than we could have imagined and I can’t recommend Concept enough. We will undoubtedly be using them again for work in the future. Thanks again to Bryan and his Team.

Latest review:
I hired Forever Construction Ltd for the renovation of my house which included rebuilding the bathrooms and kitchen along with small wear and tear and changing the electrical wiring. The quality of work was excellent and everyone in the team paid great attention to detail making sure everything was completed to a high standard and on time. The work ethics of the entire team is commendable and I was given the best advice whenever required. My adhoc requests were also accommodated whilst making sure the timelines for the work are not missed. I found the pricing to be fair and competitive. There were no surprise charges which made the entire renovation experience very smooth. I would highly recommend Forever Construction Ltd. to anyone looking for a reliable and skilled team for any renovation/construction projects.
