  • The houses are so energy efficient no central heating system is required - a first for Passivhaus schemes in the East of England

  • Runner Up for The Askham Award (recognising creative and sympathetic use of existing land or buildings) at the Campaign to Protect Rural England Norfolk Awards 2015 

  • Green Apple Silver Award 2014 

  • Finalist in the Architectural Design category at the UK Passivhaus Awards 2014 

  • Best New Affordable Housing Scheme at the Housing Excellence Awards 2014 

Sustainability was the key driver for this development, which saw 50% of the properties reach Passivhaus standard, resulting in outstanding homes for local people that were so energy efficient that no central heating system was required.

On land donated by Lord Hastings with the proviso that the homes would represent maximum sustainability and exemplar design, Lovell built eight homes on two sites, with the four homes at Fulmodeston built to achieve Passivhaus certification. Development was permitted under the Rural Exception Housing policies to provide affordable homes for local households.

The area suffers from high fuel poverty, low average incomes and no mains gas provision. The Passivhaus approach significantly reduced energy costs, leaving householders with disposable income to afford their home, free from risk of fluctuating fuel costs.

Maximum sustainability

The four properties at Barney were built to achieve code level 3 and the four homes at Fulmodeston were built to achieve Passivhaus. The core focus of the Passivhaus standard is to reduce the requirement for space heating and cooling through the use of efficient building fabric, whilst also creating excellent indoor air quality and comfort levels.  In addition, the homes had: 

  • Thermo-efficient building materials 

  • 210 litre rainwater butts to each property 

  • Double-glazed windows - or triple-glazed windows to the Passivhaus certified homes 

  • Solar shading to prevent homes from overheating 

  • Mechanical Ventilation Heat Recovery 

  • Water-saving devices to bathrooms and kitchens 

  • Low energy light fittings to all properties 

The houses are so energy efficient that no central heating system is required, which was a first for Passivhaus schemes in the East of England.

The homes were constructed using a panelised SIP system offering very high levels of air tightness and reduced thermal bridging. Passivhaus-accredited composite windows add to high energy performance and ensure indoor comfort. Shading is provided by larch brise-soleils with locally-sourced larch lapped rain screen cladding chosen for the façade.
