Mayfield Barn

Long Crendon, Buckinghamshire

An award winning low-carbon barn conversion in the Buckinghamshire countryside.

Situated in fields just outside the village of Long Crendon, with endless views across the Oxfordshire and Buckinghamshire countryside, the overall objective was to create a unique, client specified family home with the lowest possible carbon footprint.

The main glazed face is triple glazed with a canopy positioned to offering shade in the summer and allowing solar gain in the winter. A bio-efficient waste system, air source heat pump, EV charging point and low carbon internal fit-out by Barr Kitchens and Barr Joinery (using ultra-low formaldehyde MDF and high-grade ply, thus serving to minimise manufacturing greenhouse gas emissions) are a few of the extensive list of considerations which made Mayfield Barn a truly outstanding eco-build.


Re-use of the concrete base and the metal and concrete frame resulted in a significant reduction in new materials manufacturing and transportation, as well as reduced site waste transportation and treatment.


An eco-friendly air-source heat-pump, by Scandinavian manufacturer NIBE, was installed to provide Mayfield’s heating and hot water, specified through collaboration with Nu-Heat (UK certified NIBE suppliers) and Thompson Heating and Plumbing.
