The Old Corn Mill (which comes to us via World Interior Design Network) in Sheffield, England, has more than one claim to fame. This three-storey mill was built way back in the 1750s and, thanks to a recent renovation, is still in use today. It’s also one of just a few ‘carbon negative’ structures in the United Kingdom.
This intelligent renovation added two storeys to the old Yorkshire stone building in the form of an aluminium and glazed extension. Other noteworthy additions include two wind turbines in the building’s adjoining pastures, roof-mounted solar photovoltaic panels and a hydro water turbine planned for installation this summer on the weir on the River Don, which flows past the development.
A geothermal ground-source heat pump system provides warm air in the winter via a radiant, in-floor heating system supplemented by a heat recovery mechanism for maximum efficiency.
Interested in renting a suite in this “energy-efficient rural eco-office?” Units are currently available for £12.50 ($ 20.33) per sq ft per individual suite–though the developer would like you to keep in mind that operating costs at the Old Corn Mill are expected to come in around 75% lower than a conventional building for heating and around 35% less for power. A complete fact sheet is available online [PDF].
