Our Commitment

Sustainability Built In

Castlethorn understands the importance of the natural environment and the immeasurable value it brings to the built environments we create.

From the very beginning, we have worked with nature across our developments – preserving trees others would have removed and reducing the impact of construction on the landscape.

In more recent years, we pledged to find ways to build the renewable energy properties we now deliver. In that time, our team achieved a number of industry firsts, but we are always striving to do better.

Today, we use innovative, energy efficient materials and technologies to build sustainable communities. And, by working hard to protect plant life, waterways and wildlife habitats in the areas where we operate, our developments achieve a harmonious balance with nature.
