A&f is a specialist design consultancy dedicated to delivering high-tech urban agriculture projects and developing the architecture of Building Integrated Agriculture. We work with building owners, operators and developers to introduce appropriate models of food production into their buildings with a particular focus on the rooftop greenhouse model employing water-based growing techniques.

​

Our enquiry started from a genuine dissatisfaction at how urban roofscapes have become so underutilised, undervalued and unloved. You may have also considered how much more liveable our cities would be if their outermost "skin" were planted or activated. This has been changing in recent years with growing demand for green roofs, solar PV/thermal and activated roof terraces, but building owners either consider these to be a maintenance liability or a rental income opportunity cost.

A&f believe there is a huge amount of untapped value in our roofscape yet to be realised. Consider a typical, London Georgian terraced block and post war high density housing block. Their pitched and flat roofscapes were built to divert rainwater and house mechanical plant. Exposed to sun, rain and temperature variation, their facing materials degrade and impose a maintenance liability and a risk of failure while generating no revenue. Our basic proposition is that rooftops be designed as a harvesting site rather than a defensive shield against valuable incident water and solar resources.
