Bath Road, Hounslow

Greengage are pleased to be supporting Galliard Homes in the design of their development at Bath Road, Hounslow. Galliard Homes are seeking approval for the redevelopment of the site currently occupied by the Yates pub at the top of Hounslow high street. The mixed-use development includes 248 co-living units with associated communal spaces, flexible office space and retail spaces within a single development proposed to be centrally managed and operated.

Within the current planning context the development is considered as sui generis as it does not fall within a typical planning use class. Policy H18 of the draft London Plan recognises this new form of development and has been considered as a material consideration in bringing forward the scheme.

Greengage are providing sustainability support, working closely with the team to ensure that the development is brought forward with sustainable design as a core principle. Greengage have worked with Galliard to develop a new sustainable design framework which has been implemented on this project. The key result is to ensure that actions are undertaken at the earliest opportunity such that sustainable enhancements can be incorporated into the design. A key example includes undertaking a building Life Cycle Assessment and provision of ecological enhancement advice to ensure that the outputs can be considered in the designs.

Balancing the counteracting objectives of daylighting, overheating and energy efficiency has been fundamental to creating a low energy, comfortable building. Early stage architectural plans were quickly developed into 3D models for interrogating the possible building form, solar shading and glazing strategies. This work culminated in a TM52 and TM59 analysis of the development to demonstrate that appropriate overheating mitigation measures were built in.

The energy strategy for the development was based around futureproofing against an ever-decarbonising electrical grid and employing modern heat pump technology to provide decentralised heating and cooling. This approach, combined with an efficient building fabric and heat recovery ventilation meant that predicted carbon emissions were significantly better than policy requirements. Employing this technology allows a transition to net zero carbon emissions in the future.
