Plastering- 13 Jun 2020
Andi and his team were amazing. They removed the existing plasterboard ceiling and replaced it then plastered the walls and ceiling. His price was very reasonable and job was done to a very high standard. His team were very friendly and their work was clean. Andi even went out his way to help me pick up a few heavy items from shops and load it in his van. Cannot fault his work and finished work on the time scale given. Recommend to all. Thanks to Andi and his team for giving my house a fresh look.

Extensions- 12 Aug 2020
I hired Leo and his team to build a custom garden room which incorporated a Gym, living and games area. From the very beginning to the very end of the project Leo ensured the project was run like clockwork and I was updated on a regular basis. The project came in on price as agreed and he was also flexible to allow for additional or adapted works. I cannot fault Leo and his team's efforts and determination to deliver outstanding quality and workmanship in a timely manner. Builds will generally have some snags given the number of variables but in this case they were minimal and completely outside of Leo's control and were due to Covid 19 restrictions however Leo managed them really well for us. Communication and updates were excellent. The site was left cleared and they have left us with only positive thoughts.

Tom has provided a really excellent service throughout the job. He gave us a number of quotes as we changed and refined our plans and he made some really helpful suggestions about how best to proceed. I was very impressed with his project management, I always felt that I was kept up to date with the progress of the job. The quality of work from Tom and his team has been great and we even completed a week ahead of schedule!

Extensions- 22 Dec 2021
We could not be happy with the work that has been done by SJC Construction. They have gone above and beyond and very true to their word! The work was completed to a high standard in exactly the quoted time frame, exactly to the quoted price! They have made the whole process stress free and genuinely are a lovely group of guys, polite and efficient! Will be continuing to use them now for the rest of our work on our property and would be our first choice if in the future any more building work/ renovations need to be done :)

Tony & Nicola Nugent 7 Bramley Gardens South Oxhey Hertfordshire WD196YD 07892 683 819 Whilst requesting quotations from contractors we came across Martin davies and requested if he could visit and quote us for a single floor extension. As this was a big deal for us financially I needed to make sure I was doing the right thing and ended up getting around 7 quotations from different builders. Martins quote was very competitive and after meeting him we decided to go with him. For us it was a great move especially as we have never done anything like this before. Martin from the start has been great, he kept us up to date all the way through with what the next step is and what are options were whilst giving us ideas from his experience and knowledge, nothing ever seemed to be too much trouble, whether it was myself or my wife asking for additional bits or even rescuing our cat from the house roof ! The team Martin uses are also brilliant, really friendly and genuinely nice guys, Tom the Electrician was brilliant and again nothing was too much trouble. I have quite a few friends who also work in the building trade and all have commented on Martins work that it is done to a high standard, this includes my father who was a builder for over 30 years. I would highly recommend Martin and certainly will be using him in the future for more works, I’m more than happy to be contacted for further information, also happy if you would like to visit and take a look yourself!

Extension Builder in Gerrards Cross
A specialist loft conversion company that has been in business for 20 years, however, we have since branched out to all types of projects (extensions, refurbs, garage conversions etc). We can prepare and submit drawings on your behalf, for Planning Permission and Building Regulation Approval. Also, we can carry out the structural design, meaning you don't need to employ an architect! However, if you have drawings done already, we are happy to price your project and build from these.

Asset Lofts came to our rescue when another company had let us down. They were professional and genuinely supportive right from the outset. The loft conversion (inc. full chimney removal) and patio works were completed in 5 weeks and this in our eyes was a building miracle. The workmanship and finish is of the highest standard. They hold accreditation with many of the industries leading bodies and that sets them apart from others. We highly recommend them.
