Extensions- 2 Mar 2017
I used the firm's services to build an extension. Darek himself seems to be a hardworking and reliable individual. Problem is - he surrounded himself by some not very professional people, including close family members, who make things much worse for him. The other problem was that most of his team members do not seem to have much loyalty to the firm and are ready to jump to a different job any time. We had a terrible delays with our project and some things we had to completely re-do using 3rd party services. If you can ensure Darek is 100% committed to your job - could be a good project, if not - please await problems (just like I had)...

Bathroom Fitting- 6 Mar 2026
What a great team! Muneeb and his team finished the job in time, turned my tired old bathroom into a wonderful new space. Price quoted was half what we were being quoted by others. Muneeb just focused on this job rather than many others who leave the customer waiting whist doing multiple jobs. All materials used are top quality and nothing was too much for him. Muneeb kept variation minimum and agreed details in advance. Thank you Muneeb and team

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.

Extensions- 2 Nov 2018
Building a 2 storey rear extension and hired Jamal to do the Block work. Initial ground storey heavy Hollow block walls for the 3 x 3m extension completed in only 3.5 days by Jamal himself with no extra help. Hardworking young guy. I was nearly bedbound with sciatica and in great pain and he immediately offered to source and buy on my behalf extra blocks required to relieve further stress on me. Very helpful, reasonable and understanding. Explained anything I asked him diligently. Knows his job and I will be calling him back when I have the money to complete the block work for the 2nd storey.

Bricklaying- 6 Jun 2026
Absolutely fantastic service from start to finish! The team demolished our fallen garage and built a brand-new one to an excellent standard. Communication was brilliant throughout the entire process, keeping us informed every step of the way, and the turnaround time was much quicker than we expected. Everyone we dealt with was friendly, professional, and always happy to answer any questions. The workmanship is outstanding, and we're extremely pleased with the finished result. I wouldn't hesitate to recommend them to anyone looking for a reliable and professional company. A big thank you to Teresa, Jason and the team. Thank you for a job well done!
