Green Agent is a deep-retrofit consultancy for London period property. We start with the fabric — the materials, and the way light, air and heat move through a house over time — because that is what decides how the building performs, and how it feels to live in.
Simply healthier homes.
Kingswood Avenue, NW6
“I just call it a healthy home.”
I’m Duncan. My MSc in sustainable design at the University of Sydney focused on adaptive thermal comfort.
For over twenty years I’ve tested one line of inquiry across three London retrofits — from Keslake Road in 2003 to the current flagship at Gayton Crescent, Hampstead.
That work has been featured in the Financial Times.
We work on the fabric of existing buildings, because the way a building behaves depends on the materials it’s made from — and how it behaves shapes how the people inside it live, sleep and breathe. Get the fabric right, and the comfort, the running costs and the long life of the home follow as a consequence, not as features bolted on.
A scoped review of a single property, coordinated by Duncan with a curated team of specialists. A clear pathway, the performance modelling, and the economic case.
End-to-end leadership of the retrofit, from planning through to completion. Duncan is the constant; the team is built around the job.
For owners of multiple properties — long-view, lifecycle thinking, with energy savings folded into the investment maths from the start.
Retrofit in the UK is too expensive, too fragmented, too slow. Policy, finance, supply chains, contractors and owners all pulling in different directions — a lot going on, none of it connected. Green Agent exists to be the agent for change in the existing housing stock.
