Years Combined Experience
Who we are
Kingsmarque is a family-run company built on years of experience in the construction industry. The business was established to place honesty, quality workmanship, and pride in the finished result at the heart of every project.
Together, Keya and Development Manager Roy Burtt bring more than 40 years of combined experience, and they stay personally involved from early planning through to completion. You deal with the people responsible for your project, not a sales team.
