We have undertaken 100's of projects

Our Mission

Our mission is to become the UK's number one Loft Conversion and Extension Company, by providing the highest quality of workmanship with exceptional customer service.

Our vision is to operate a company that not only builds properties but also develops real connections with our customers and building trust that lasts a lifetime.

Quality London Extensions and Loft Conversions

We aim to remove the stigma from the title “builder” and take construction into a new era. We understand that deciding to go ahead with any project can be a daunting experience if not handled correctly, but we are confident we can help you build your dream home.

Using our years of experience, we strive to offer the best service we can with detailed plans created using the customer's specifications. At The Market Design & Build, we are constantly growing and aim to provide services nationwide with experienced area and quality control managers operating across the UK.

  • People - To be a great place to work and progress, creating a community between the company and the clients.

  • Partners - To be open and honest with all partners in the build process which includes supplier, third party contractors and our clients.
  • Productivity - To be a proactive team that anticipates rather than reactive.
