To rebuild or to retrofit? That is the question posed by former Secretary of State Michael Gove’s intervention in planning applications for the redevelopment of M&S’ Oxford Street store and the former Museum of London building.

According to the Climate Change Committee, direct and indirect greenhouse gas emissions from buildings account for 23% of the UK total.

How can we create energy-efficient, carbon neutral and climate resilient new buildings and what is needed to accelerate the decarbonisation of existing buildings?

The greenest building, so it is said, is the building that already exists and a ‘retrofit fit first, not retrofit only’ position appears to be emerging as the default, but this involves understanding which development options would have the lowest embodied carbon intensity and operational carbon emissions. Who is measuring what and how?

Friend of the podcast Katie Wray kindly convened a group of experts in this field to tackle these questions in a conversation recorded online in April 2024. Katie, Director in Real Assets Advisory team at Deloitte, spoke to Iain Shaw, Mike Keaveney and Alex Edwards. Iain is a Director at Max Fordham, Mike is a Land & Development Director at Grainger; and Alex is ESG Director at Bruntwood SciTech.

They talk about where the drivers for change in this area are coming from, how decisions around rebuild and retrofit are arrived at, and the concept of ‘value for carbon’.

If you have listened to Episode 45 of 50 Shades of Planning you will have heard Clive Betts say that...

'In the Netherlands planning is seen as part of the solution. In the UK, too often, planning is seen as part of the problem'.

Sam said in reply that that would look good on a t-shirt and it does. Further details can be found here. You can also sign up for the 50 Shades Newsletter via the 50 Shades Blog.
