The capital’s mayor Sadiq Khan has released new guidance for developers to ensure new buildings are greener prioritising space for walkers, cyclists and public transport users.

The guidance is part of Mr Khan’s plans to make London a zero-carbon city within the next ten years and offers practical advice on how to do it.

He said: “I’m committed to delivering a brighter future for London – one that’s greener, fairer and more prosperous for everyone.”

Mr Khan said it was vital London adapted to the impacts of a changing climate, including the increased risk of flooding and overheating.

The guidance requires developers to monitor and report the operational energy performance of major developments for at least five years post-construction. The mayor sees this as a critical step in moving to net zero-carbon buildings.

They must also calculate their urban greening score with initiatives such as green roofs, rain gardens and flower-rich gardens gaining higher points for being a big benefit for the natural environment.

The guidance also offers advice for London councils in setting their targets which are particularly aimed at boroughs deficient of green spaces and features.

Making room for sustainable transport is key

Fostering sustainable transport for new developments also forms part of the guidance. The mayor wants to see space devoted to new walking routes and cycle networks. Enough room for public transport infrastructure such as bus garages, rail depots and tram stops is also required.

The sustainable transport, walking and cycling London plan guidance offers developers and boroughs advice about how to achieve this when proposing new schemes and drawing up local plans.

Brokers Hank Zarihs Associates said development finance lenders were keen to fund proposed London projects with strong green credentials.

The Greater London Authority, GLA, has halved its projected housing starts on its own land over the next two years due to construction market ‘turbulence’.

Its latest housing delivery report projects 3,500 starts on land owned by its bodies in 2021-22 and 2022-23, down from the 7,311 forecast in its March report.

Mr Khan has commissioned an independent review led by Lord Bob Kerslake to see how the GLA can improve and streamline housing development. The review’s final report is expected in early 2022.
