The Market Design and Build has just finished a big project for us and we couldn’t be happier. The property is an old converted barn so the challenge was huge. Obviously there were some set backs but the communication in between us (property owners) and The Market was excellent so problems were solved quickly. These guys are not here to screw you over. Before signing the contract they guaranteed us that they wouldn’t leave the project until we were 100% happy.. And they didn’t! We are sure to use The Market again if we need more work done on a property in the future.

Project date: October 2016
We chose The Market Design and Build to do full refurbishment of the ground floor (including removing chimney breasts and a structural opening), rear extension as well as construction of an outbuilding at our home in Ruislip which has just completed. After running a tender process, we chose Market Design and Build based on their credentials and detailed response to the tender documents and competitive price. We wanted the work to start fairly quickly and The Market Design and Build was fairly accommodating. We were allocated Jigs (Jignesh) as our Project Manager and Sukhi as our builder; they were both absolutely brilliant throughout the project and provided some valuable advice and suggestions that we are grateful for. Jignesh ensured that the work is completed at high standard as per the agreed project plan, thereby ensuring the project didn’t run over the agreed time scales. Sukhi (our builder) was very very good and was happy to accommodate any minor changes that we requested. He provided us with an overview of the plan each day and ensured he was checking in with us to ensure that we are happy with the work. We have been consistently impressed by the hardworking team and their subcontractors. Both Jignesh and Sukhi have shown an eye, and a passion to deliver the project to a high standard. Regular site meetings and prompt team updates ensured that we were in the loop on progress and any issues at all times. Even during the messiest and dustiest phases of the build, the site was kept as tidy as possible, and generally speaking, nothing was ever ‘too difficult’. We have no hesitation in recommending The Market Design and Build especially Jignesh and Sukhi (dedicated team for our project) – this is the level of service and quality of project delivery that construction firm should be striving for.

Being first time extenders/renovators, we chose to use the Market Design & Build for our extension and complete renovation from initial architect design to completion of the build. The first design was drawn quickly and efficiently and then with further discussion and advice adjusted to suite our needs. The 3D model and CGI really helped us visualise what we were working towards. They applied for and pushed through our planning application which had delays due to COVID. The quote for the build was fully explained and further advice was given to us as needed. There was no pressure at this point to proceed but we felt in good hands. Once planning was successful the build commenced within a matter of weeks. Our project manager Hamael was always contactable and discussed any issues with us and kept us updated on progress. As with all builds we had some bumps in the road and some extra work that needed doing and these were dealt with and the project remained largely on track. The build team were efficient and courteous and lovely to deal with - to name a few particularly Sonu, Sonu and Ravi. Post build and moving in any snags that we have identified have been dealt with when requested. Communication has remained open and we are confident any other snags or other issues covered under the 2 year warranty and 10 year guarantee can be dealt with. We would highly recommend this company and if we were to do a similar project in the future we wouldn’t hesitate to use them again.
