Who We Are


The Market Design & Build was established after having a home extension built on my own property several years back. This was where I realised there was a gap in the market in terms of building management.

There were several key aspects missing, including lack of structure in terms of the work being carried out on my property, a distinct lack of communication and poor timekeeping. I, therefore decided something had to change and inspired me to take a stand and reshape the industry.

BSc (Hons) Residential Property Surveying

A True Design & Build Company


Having studied a Residential Property Surveyors Degree at university, I then went on to work as a property surveyor for a large London estate agency, which is where I truly discovered my passion for the construction industry. Whilst there, I soon realised that several key aspects were missing from the industry I had grown to love.

What started off as a small hobby has quickly grown to become my absolute passion. Builders often have an unfriendly label attached to them and it was my goal to try to break this stigma, by creating an honest communicational structure within the workplace – one that is transparent from start to finish and includes the customer during every step of the process.


Throughout every project, our complete focus is on design, service and execution. We have a dedicated team of specialists for every project, ensuring that everything runs smoothly and fits a timescale within budget, without compromising quality.


We are now one of London’s leading home conversions companies. Since our formation, we have undertaken 100s of projects; from loft conversions to full house refurbishments and to brand new build – no job is too big or small. We have an impeccable reputation for customer service, which is why so many of our customers return to us and will also refer us to friends and family.

Expert Builders in London

As a company, we have grown exponentially and have started to make a major impact on the industry. We found that communication was a key ingredient which was lacking from the existing building companies, hence why we appoint area and quality control managers to be on hand every step of the way. This allows the client to relax and actually enjoy watching the building process unfold.

We specialise in providing a first class service, with the best workmanship to match. We have and always will use trusted specialised teams for every part of the required project.

For examples of our work and completed projects, please visit our Case Studies page.

With no deposit necessary, a 10 years guarantee and over 550 positive reviews on Checkatrade, it's easy to see why our customers keep coming back. Please contact us today to arrange a consultation.
