Delivering Value-Added Construction

GPMM Build Limited was set up and incorporated in 2017 by Paul Greengrass and Gary Simpson, combining their extensive experience in project management and commercial construction.

From the outset, their vision was to create a company that delivers value-added construction services, providing clients with not only high-quality builds but also expert cost planning and project management.

With years of hands-on experience across both the residential and commercial sectors, Paul and Gary understood the challenges clients face during construction projects. They wanted to create a company that brings clarity, efficiency, and peace of mind to every project.
