Bushbury Hill Primary School
Download
as PDF Bushbury Hill primary school was one of the first projects in the country to achieve Passivhaus certification in February 2012. The school was built to the same budget and completed in the same time frame as a traditional build. Due to the challenging nature of the site, there was extensive consultation with the school and its neighbours throughout the design and construction process.
