About CO2 Architects

Established in 2001 the company has quickly established a reputation for innovative design, that is creative and powerful, yet responsive and holistic, working in a broad range of urban and environmentally sensitive rural areas within Wales, England and France.

The company was founded on premise that architecture can serve as a bridge between nature, culture, history and people; and we believe that our sensitive approach towards design help's to produce the best building's possible.

Over the past decade and a half, the firm has grown and broadened its expertise beyond the projects for which it is best known, and we consciously devote a consistent energy and enthusiasm to every project, no matter wether the task at hand is a simple extension or a large scale housing project. We endeavour to ensure that every finished project manifests in a "macro to micro" level of detail, giving a complete coherence to the entire experience.

We strongly believe at CO2 that stimulating and rewarding architecture can be achieved, no matter how large or small the budget.

"Architecture can serve as a bridge between nature, culture, history and people; and we believe that our sensitive approach towards design help's to produce the best building's possible."

Our team

Our designs aim to minimise our impact and celebrate what is special. At CO2 architects we strive to seek simple solutions that deliver maximum results. Getting to know our clients well is important to us and the cornerstone of every project. Good relationships lead to better projects, and we're proud of our close relationships with local builders, engineers and planning officers.
