Since its launch last summer, could you provide an update on how you have worked with housebuilders to roll-out the PRISM app and could you provide any examples of where it is being used by GLA partners, and will it feature in the housing design guidance being published later this year?

Since its launch in June 2019, officers have commissioned Bryden Wood Technology and Cast Consultancy to undertake further enhancements to the Prism design app. This further work includes new design features and typologies, the inclusion of additional precision manufactured housing (PMH) systems and an improved user interface, as well as targeted engagement with GLA partners to consider how the app could be used to support greater uptake of PMH on new schemes. The updated version of Prism is expected to be released later this year.

In addition, the app enhancements ensure that the app is better aligned with requirements outlined in the draft Design Supplementary Planning Guidance (SPG), with notifications provided to users when certain design and planning standards are breached. The SPG does not include specific PMH design standards, as all housing schemes are expected to meet the same design requirements regardless of the construction method used.
