Hanham Hall is the first site in the government’s Carbon Challenge initiative and is scheduled to become one of the first zero carbon communities in England. 185 new homes are proposed in the grounds of the former hospital structured around a series of green spaces with allotments, orchards, hedges, ponds, cycle and walking routes. A restaurant, nursery, community hall, cafe and offices are currently proposed in the Hall.
The most significant challenge at Hanham Hall has been to design a scheme that will meet the stringent requirements of Code Level 6 whilst being acceptable to all stakeholders. To achieve this balance we have worked closely from the very start of the design process on a structured engagement programme with vast range of parties including our Client and design team partners, the Parish Council, the Homes and Communities Agency, English Heritage, South Gloucestershire council, the Green Belt Society, local residents, and the supply chain.
The homes are much better in energy performance than the current UK building regulations standard. The historic building will be refurbished to the highest UK sustainable office standard for reuse as a community and employment facility.
The homes are built from factory made elements which minimise waste and which are energy efficient to produce and build.
The complex brief required a comprehensive approach and all HTA disciplines contributed at varying stages of the project. The ability of HTA to offer these numerous disciplines provided the client with a more coherent response to a challenging project. The requirement for the refurbishment of the Grade II* listed Hall was also managed by HTA where we found the coordinating disciplines especially effective in achieving BREEAM targets.
The development will become a benchmark for sustainable housing development by using the following features: cutting edge building technology in the form of SIPS panels; meeting the projected 2016 Zero-Carbon targets; an innovative community management structure, a development trust; integration with the existing ecology and landscape; sustainable refurbishment of a historic building, and allotments and an orchard. HTA worked with the supply chain to ensure that the latest technologies were used in the most effective manner on the project, and in a way that was practical for the client to build.
Prototype units were constructed by Barratts and tested by Oxford Brooks University in collaboration with HTA to test them for compliance with all the demanding standards. These tests included sound, airtightness and co-heating tests. The prototypes passed with flying colours and some of the new homes will be monitored for up to two years to assess their performance in use.
