ZEDfactory began as Bill Dunster Architects in 1999. From day one, the company has been exclusively committed to low carbon building and development. Using tried and tested technologies, ZEDfactory creates designs that are stimulating and practical on a daily basis, yet distinctive, economic and reliable in the long term.


Today, ZEDfactory is a leader in the field of zero-carbon design and development, with a unique track record of delivering Zero (fossil) Energy Development (ZED) buildings in the UK and worldwide. The company offers the full range of architectural services, from master-planning and design of large-scale ‘Eco-villages’ to one-off individual building commissions. 

The ZEDfactory also works closely with leading UK academics and consultants to model predicted energy consumption and production, fluid dynamics and whole life cycle carbon costs of their designs to ensure they achieve the lowest environmental impact possible.

The ZED Factory is a leading light in low-carbon living. We have extensive experience in the design and realisation of energy efficient buildings of all types and sizes. The company’s designs for zero carbon building projects are sought out by clients around the world.

The ZED Factory believe that sustainable development is both affordable and achievable within current market constraints. Our design approach integrates as many building elements as possible into construction. This results in fewer components and finishes being needed. The associated cost savings allow a higher specification for low energy and low-environment impact components.

Renewable energy devices and passive energy features are an inherent part of our design thinking. Structural considerations and fixings are determined during design, so that components can be added later as required, rather than as an expensive after thought.
