We have worked with Patterson Construction for a number of years on varied contracts and have found them to be very professional and thorough in all aspects of the work involved. We have learned a lot from their problem solving initiatives on difficult contracts through to their steadfastness in ensuring contracts completed on time.

We worked with Patterson Construction Limited on a very complex basement in Shoreditch. PCL went down 2 levels in concrete and waterproofing and up 4 levels in steel. There were numerous problems on the project and they overcame each and every one. We now have a very successful hotel and restaurant and I would recommend these guys to any main contractor.
