From 2012 – 2016 Transition Town Lewes ran an event: Open Eco Houses.
Local residents who had eco upgraded their homes made themselves available for a weekend to share their experiences and demonstrate the work they had done. Below are links to the publications produced, for some in depth analysis of what is possible in retrofitting a Lewes home.
