Andy is a RIBA Chartered Architect with nearly 30 years of experience at the intersection of architecture, sustainability, innovation and policy. His career has been directed by a single question: how do we make homes better? Genuinely harmonised with our systems and ecosystem, so that our homes are truly places of joy and sanctuary.
That question has taken him from architectural practice and off-grid new builds, through a decade of national research and innovation programmes at BRE, to co-founding Sero — a Cardiff-based B-Corp now widely recognised as one of the UK’s leading net zero housing businesses. Along the way he has conceived and led programmes that have shaped Welsh Government policy, mobilised hundreds of millions in public investment, and helped reframe how the housing sector thinks about energy performance and mortgage affordability.
Alongside technical depth, Andy brings a systems-thinking approach rooted in architectural discipline: an ability to hold detail and whole together, to connect design, policy, finance and lived experience, and to build the evidence base that makes ambitious ideas deliverable.

The best ideas rarely come from one perspective. Across our projects, we work with a network of specialists, researchers, and industry experts — people who bring deep knowledge in areas like energy modelling, building physics, housing policy, data science, and community engagement.
We don’t maintain a fixed roster. Instead, we bring together the right people for each challenge — drawing on long-standing relationships built over nearly three decades of collaborative work across the housing and retrofit sectors.
If you’d like to know who we’d bring to a specific conversation, just ask.
Claude is an AI built by Anthropic that helps with background research, data gathering, and the sort of legwork that would otherwise eat into time better spent thinking. Claude also built this website, which it’s quite pleased about.
Mostly, Claude trawls the web and re-reads documents to help ensure a thorough review and understanding.
