Project Overview

Hanham Hall is England’s first large-scale housing scheme to achieve the 2016 zero carbon standard and is one of the flagship Carbon Challenge schemes promoted by the HCA.

The development provides 187 new homes for private and affordable housing. Central to the vision of the development, the Grade 2* listed Hall (a building of special interest, warranting effort to preserve it) provides an important sense of identity and history, adding vibrancy to the community through uses such as office space, a crèche, and cafe. Green belt restrictions and the need to retain views of the Hanham Hills meant more than a third of the site could not be built on. Views and natural light were thus prioritised and the homes have large windows, balconies and verandas for the wellbeing of residents.


All homes achieve the new ‘Zero’ standard and outperform the building regulations and other widely used industry standards.

Remaining emissions were offset by a number of approaches including installing LED lighting in local schools as a test of the Allowable Solutions standard.

Approaches Used

  • The homes are built from factory made elements which minimise waste and which are energy efficient to produce and build, taking two days to construct the building envelope of each home.
  • The zero carbon standard is achieved by using a very efficient building envelope constructed using Kingspan TEK Structural Insulated Panels (SiPs) and roof-mounted photovoltaics which varies with home typology. Each home has a Mechanical Ventilation and Heat Recovery system and a minimal heating system. Due to the high insulation levels, the need for space heating is much reduced.
  • The Hall, which is a Grade 2* listed building, has been refurbished to a BREEAM standard.
  • The external works have been designed in accordance with the CEEQUAL standard.
  • The homes are designed to avoid overheating and use manually-operated shutters to give residents control over their comfort, daylight and security.
  • The homes meet the Lifetime Homes and the Building for Life standard.
  • New homes were monitored for two years to assess their in-use performance, demonstrating that, on average, the homes perform as predicted.
  • The Initial Building for Life 12 assessment showed 12 green lights.
  • Roads have shared surfaces so pedestrians and cars and bikes can use the same paths, and roads are linked to cycle paths to encourage people to drive less and walk and cycle more. Homes are 10% larger than open market housing and discrete street parking ensures main public spaces have reduced car parking.
