The Team at TMDB have undertaken a architectural design package for us including Structural calculations and building regulation / technical plans very happy and would love to proceed to the next step with the team in to the build. They keep me updated on all stages of the process and when certain stages were delayed I was advised of this delay as soon as the information was available. I will be using TMDB for my next project and all future projects moving forward. Thanks again to the Team!

Recently we had a empty unit near our warehouse. We approached the market for some ideas and their expertise. Overall the outcome was multi unit schemes which maximised the space and potential of the unit. This was a great idea and we cant wait to start the build stage of this project

We have undertaken a set of structural calculations for my personal house, great service would highly recommend, it was a complicated job as the job had been undertaken by a different engineer for phase 1. Great team and service.

Architectural feasibility for a new bunglow, my first architects really let me down and the team at the market design and build have really stepped in to help us. We have a long way to go but very excited about the prospect of adding a new unit on the existing property. As a developer and someone who has been in this game for a long time it is refreshing to see a team so dedicated and willing to work on such short notice for the many sites we have and are trying to acquire. Cannot recommend the team enough. Absolutely took the stress away. The strength of any developer does not depend on the execution of a project but in the professional team to get the planning over the line. Great work guys. I'll be sending you guys a thank you in the mail

Having used The Market Design and Build for our previous home, it only made sense to use them again for our new home due to the experience we had. We used them for our planning, designing, structural designs and build! The planning advice they gave was invaluable. It’s helped shaped our home to something we’re now proud of. We decided to use the team for our build too. This as mentioned above was based on our past experience and they have lived up to our expectations. Would definitely recommend the team, it’s been a stress free process for us. Planning on using them for our “Phase 2” too!!
