Biddenham Turn, Bedford, Bedfordshire, MK40 4AZ

The largest zero carbon property in the country.

An outstanding triple Schoolhaus® development for this foundation school in Bedfordshire.


Net Zero Buildings initially built the first phase (of three) Schoolhaus® buildings in 2014 as part of a wider project to upgrade energy efficiency throughout the estate. Biddenham is a very successful, expanding school in Bedford where the governors and local authority wanted to establish a new middle school for Years 7 & 8. We were asked to develop a ‘campus within a campus’.   

Summer 2017

Biddenham’s triple Schoolhaus® building complex was completed (early) over the Spring and Summer of 2017: two mirror classroom blocks for Year 7 and a larger single building for Year 8. At 2300 m2 , these combine to make up the largest net zero carbon property in the UK.

All three buildings are EPC rated A+ (-25, -29 and -34 respectively) ie, better than net zero.
