Celebrating 25 years

The time seems to have gone so quickly but, amazingly, 2020 sees Green Building Store celebrate its 25th year of operation. Originally based in a shed on the side of Director Bill Butcher’s house with 2 staff (and a dog), the company now has 36 staff and a national reputation for low energy building products and expertise. The company has changed and evolved considerably over the last 25 years, illustrated by its switch to promoting the Passivhaus low energy standard in 2009.


Over the last 25 years we have seen interest in green building grow steadily. The good news is that we are now (finally) finding greater uptake of low energy building by councils, businesses and individual selfbuilders. The bad news is that national Government policy is still not providing the drivers and incentives that are so urgently needed. We are proud of our role in helping the UK take up Passivhaus and low energy building and look forward to the next 25 years!
