Our purpose is to drive the transition to a low-carbon built environment across Sussex and the South East through regenerative architectural design, retrofit-first strategies, and healthy, bio-based materials - creating resilient spaces that enhance human well-being while restoring local ecosystems.

Company Strategy

As an architectural practice operating in the UK building sector - where construction and building operations account for nearly 40% of global carbon emissions - our purpose is directly aligned with market demand for decarbonisation, energy security, and strict climate building regulations (e.g., Future Homes Standard, LETI, and RIBA 2030 Climate Challenge). Delivering high-performance, low-impact design secures our competitive advantage, attracts sustainability-focused clients, and future-proofs our commercial pipeline.

Our purpose governs how we allocate resources, select projects, and manage our practice:

We actively prioritise retrofit, adaptive reuse, and low-energy projects over energy-intensive new builds or carbon-heavy developments.

We integrate circular economy principles by specifying bio-based, locally sourced, and low-embodied carbon materials across 100% of our design projects.

We embed climate performance goals directly into our project briefs and client relations.

Key Metrics & Integration Mechanisms

Conducting embodied and operational carbon benchmarking on all major design projects.

Sourcing a minimum of 75% of specialist consultants and material specifications within a 50-mile regional radius.

Enforced through our public Climate Action Plan, Ethical Client Policy, and annual progress reporting to stakeholders.
