Building trusted partnerships since 1980.

Our company has a proud history. We were established by Stephen Calder in 1980 to provide the local rural community with high-quality buildings built to last.

Over the years we’ve steered successfully through major changes and have continued to innovate. Today, our ethos remains the same.

To provide expertise and a trusted partnership, and to successfully deliver, every time.
