The london Loft and Kitchen Company
Rating: 4.5 out of 5
Extension Builder in Grays Inn
We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

What a great experience we had with Louis. He is honest and gets the job done efficiently with great attention to detail. He did such a good job with our terrace. We had some problems that really needed a professional solution and Louis planned and executed it brilliantly. Instead of looking for excuses for things that could be a problem Louis had a great solution for everything we came across and was positive the whole time. Would highly recommend Louis, we already have him booked in for more jobs.

Conversions - General- 3 Apr 2026
Where do I start. I’ve had more communication with Stuart in the last few months than I have had with anyone else. Our house has rare coloured bricks and I was absolutely shocked that Stuart managed to match the bricks perfectly. Stuart completed the work to such a high standard, we have arranged for him to come back to complete the inside of the extension also. Stuart quoted a really good price, turning up on time everyday. Honestly couldn’t recommend him enough and we will be using Stuart for all future work we intend to have done.

I used to watch while others built but i have spent 18 years doing what I used to pay others for. I am a very physical person and consider quality to be my aim. I holds a 127 iq score because of my quick and efficient way of creating the possibilities to satisfy and bring dreams to reality. I am located in Hackney of London where I grew up. My practical experience extends beyond building houses but also conversion of cars and using recyclables for design. I am very open minded and inventive. Ready to satisfy.

Although I posted for a kitchen extension quote I decided that I would proceed with this at a later date. I did have a lot of other building work such as chimney removal that was undertaken by A2Z Property Improvement Limited. I am happy with the the work that was carried out. I'll certainly be reaching out to A2Z again for the extension once I'm ready to proceed. I would definitely recommend this company.
