ABOUT US

A legacy of craftsmanship and innovation.

We believe high quality is never an accident. With nearly a century of experience, our roots run deep in Guernsey. Many of our projects are key to the island’s culture and history. From the Island War Memorial in 1926 to award-winning historical building projects like St. James Concert and Assembly Hall and The Island Archive at the former St Barnabas Church, our work stands the test of time.

We are a modern business with traditional values. Our highly skilled team and first-class sub-contractors ensure premium solutions are crafted for a diverse portfolio. Our honest and transparent approach makes us the first choice for new build and refurbishment of residential, commercial and heritage building projects.

Trust us for unparalleled craftsmanship, tailored solutions, and a lasting legacy of quality.
