Who We Are

Your experienced construction partners for over 20 years in the South West & Wales

You know best the potential your space has to make the lives of your end-users better. So, let’s make your vision a reality.

At 21CBS, we let your knowledge of how people live, work and play in your spaces be our guide. After all, your built environment should fit your people, not the other way around.

As a family business with deep roots in the South West, our success over the past two decades is built on the dedication of our long-serving team. Many of our professionals have been with us throughout the journey—some for over 24 years—bringing extensive experience and continuity to your projects.

Our established teams include dedicated Contract Managers, Site Managers, and Quantity Surveyors, all committed to delivering your project with precision and care. Our clients, some of whom have partnered with us since the beginning, know that we provide the consistency and expertise needed to turn visions into reality.

Let’s create better spaces, together.
