Restoration & Refurbishment- 31 Jul 2023
We put the ad up on Saturday morning, Ed popped over in the afternoon and gave us a quote and the job was completed on Monday! Super quick process. For a job that was causing us stress and we quickly realised we couldn’t do ourselves, Ed came in and sorted it really quickly as well as giving us advice on next steps for our redecorating. Will be contacting again when we need further help!

Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.

Bathroom Fitting- 13 Oct 2015
Reece and his father did a great job in our bathroom and he was a real pleasure to deal with . He went above and beyond the role as he had to order and collect a bath end panel as he suggested it would be a better match from the one I had selected . He was correct in this. He is he first builder I have ever known to suggest an improvement, source it and collect it as part of the job !! I would thoroughly recommend him. :)

Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.
