Sustainable Architecture
Our sustainable architecture practice creates buildings that harmonise with natural ecosystems. We employ passive design strategies, renewable materials, and energy-efficient systems to minimise environmental impact while maximising occupant comfort. Our approach integrates ecological principles from concept to completion, ensuring long-term viability and adaptability of structures.
Passivhaus Design
Specialising in certified Passivhaus standards, we deliver ultra-low energy buildings requiring minimal heating or cooling. Our expertise includes thermal bridging prevention, airtightness optimisation, and advanced insulation techniques. This approach guarantees 70-90% energy savings compared to conventional construction while maintaining superior indoor air quality through mechanical ventilation systems.
Permaculture Planning
We apply permaculture principles to create productive, self-sustaining landscapes that integrate with built environments. Our designs maximise biodiversity, water efficiency, and food production while enhancing aesthetic value. This holistic approach creates regenerative systems that support both human needs and ecological health across residential and community projects.
Building Biology
Our Building Biology expertise ensures indoor environments promote occupant well-being through non-toxic materials, optimal acoustics, and natural light integration. We assess electromagnetic fields, air quality, and thermal comfort to create spaces that support physical and mental health, aligning with international standards for healthy building certification.
Climate Resilient Design
We develop adaptive designs that withstand future climate challenges through predictive modelling and material innovation. Our strategies address rising temperatures, increased rainfall, and extreme weather events while maintaining energy efficiency. This forward-thinking approach ensures buildings remain functional, safe, and comfortable for generations without requiring major renovations.

Questions
What sustainability standards do you specialise in?
We specialise in Passivhaus certification, Building Biology standards, and permaculture principles. Our work aligns with BREEAM and LEED criteria while pioneering future climate-resilient design approaches.
How long have you been practicing ecological architecture?
Since 1992, making us one of the UK's longest-established sustainable architecture practices with continuous innovation in regenerative design solutions.
What building types do you work on?
We handle diverse projects including residential developments, educational facilities, community spaces, leisure centres, and commercial buildings across both public and private sectors.
Can you retrofit existing buildings sustainably?
Yes, we specialise in upgrading historic and existing structures with energy-efficient systems while preserving architectural integrity and enhancing environmental performance.
How do you integrate nature into designs?
Through permaculture principles, we create productive landscapes that work with natural systems, incorporating green roofs, rainwater harvesting, and biodiversity-enhancing features into every project.
What makes your approach unique?
Our multidisciplinary team combines architectural innovation with scientific rigour, treating buildings as living systems within ecological networks rather than isolated structures.
