Our homes poorly retain heat in winter, and overheat in summer. We use high amounts of energy - often supplied through polluting means - to make our buildings liveable. The health and economic cost of our poorly designed buildings will only get worse over time. This is a problem that cannot be fixed by simply building new buildings better.

What if we could transform existing homes? We can improve the fabric of our buildings to achieve high comfort for residents, and maximise the use of renewable or natural energy sources.

This transformation is increasingly capable of being affordably funded with blended finance. The high cost and specialist time required to get a detailed costed design prevents sustainable finance from effectively creating the incentives for a sustainable able-to-pay market.

We are a London based team of product designers and engineers, making detailed retrofit design simple with software. Our long term goal is to build a sustainable home energy retrofit market.
