Extension Builder in Erith, Greater London
Hi there, I’m Neil, I’ve got 20+ years of experience in the construction industry. I’ve worked all over London and Greater London over the years and travelling to work is not an issue for me. I have an experienced group of people that I work with and who know how to get the job done on time and on budget. From the domestic side of the industry i.e. garden walls, extensions and new builds to the commercial side which includes retail units, office blocks and housing estates, there’s nothing that can’t be built!!! If an architect can draw it, we can build it!!! Thanks for checking out my profile and I look forward to hearing from you soon.

Extensions- 9 Jan 2019
Altun Property stepped into the project very anxiously and positive. The management were very helpful and assist us with the neighbours requirements, as our building is adjacent to a primary school. The project went thoroughly and took some time because it was a big project. Altun Property were very energetic and supportive throughout the work, they didn't object any amendment the project required and extra work needed. We have received several compliments from visitors to our office for the level of work conducted and the quality provided. Commissioning the work to Altun Property helped us heavily as a charity because we were able to save on the overall cost of the work. I would like to express our appreciation for the work conducted and look forward for further work together.

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.

Kitchen Fitting- 12 Nov 2022
I am so happy with the work and professionalism of Tom and James. I had queried several companies and decided to work with G2 brothers based on how open and honest they were on the first visit for estimation of work. We discussed the work I wanted done, which was to replace the cabinets in the kitchen. We also discussed the budget I had and what the overall look I was going for. Throughout the whole project we discussed options, impacts and agreed together on next steps. They were a pleasure to work with, I will definitely use their services again. Great work!!!
