Decarbonising existing buildings is complex, especially when they are historic, listed or architecturally sensitive. We specialise in retrofit design and carbon reduction strategies for buildings across Oxford, London and the wider UK, combining deep technical knowledge with a heritage-aware approach.

Our team includes experienced architects, retrofit designers, certifiers and building physicists who understand traditional materials, moisture behaviour and the risks of over-intervention. We assess each building holistically, applying fabric-first upgrades where appropriate, supported by mechanical system optimisation through our in-house MEP engineers.\n\nWe develop decarbonisation roadmaps for both large estates and individual assets, scaling solutions to meet budgets, operational needs and organisational net-zero targets. Crucially, we don’t stop at strategy, we assist with project delivery, helping clients implement realistic, cost-effective improvements that reduce energy use, embodied carbon and operational emissions. Our focus is performance that works in practice, protects heritage, and supports a low-carbon future for the UK’s built environment.
