The proposed development consists of the erection of two buildings for residential use (Class C3) together with associated parking, cycle parking, hard and soft landscaping, play space, access, utilities and other associated works, including the removal of the existing substation. The buildings provide 134 new-build dwellings.

The development is a social housing scheme ranging between five to seven storeys. The proposals include 67 affordable housing, 45 intermediate housing, and 22 private housing. The majority of the scheme consists of apartments with eight maisonettes. All dwellings will have balconies and terraces.

The construction will consist of a well-insulated envelope and air-tight construction, reducing the space heating demand. Appliances will be low energy and hot water demand minimised to help reduce operational running costs.

Onsite community heating will provide the dwellings with low-carbon and affordable heating and hot water utilising an Air Source Heat Pump (ASHP) only strategy. A Solar Photovoltaic (PV) array has been maximised to achieve as close to zero operational CO2 emissions as possible while also helping reduce running costs for the use of the ASHPs.

The development is to provide low-energy homes via the Passive House principles as part of a strategy in which all buildings are anticipated to achieve Classic certification.

As Passive House Consultant, we carried out initial studies to determine if the criteria was achievable. This involved regular workshops with the design team to discuss the form factor, balcony and shading strategies, insulation requirements, glazing ratio and mechanical and electrical services.
