Experiments in low-carbon retrofit for a high-status building (with a basement), with Natalie Black (Enbee Architecture + Design) and Toby McLean (Allt Environmental Structural Engineers)

This week's episode is all about the lessons learned in carrying out a low-carbon retrofit.

Natalie Black (Enbee Architecture + Design) and Toby McLean (Allt Environmental Structural Engineers) joined us to talk through their experiments and experiences on the renovation of a derelict house in Muswell Hill, London that was shortlisted for the Architects Journal Retrofit and Reuse awards this year.

This is a project that could easily be misrepresented as a Grand Designs-style endeavour that's only representative of what you can do if you've got loads of capital and capacity, but that wouldn't be fair. This project should really be seen as an example of what you can achieve when you've got loads of capital and the capacity to experiment.

The lessons learned here aren't going to solve the housing crisis but they can contribute to resolving the climate crisis, and this is what's motivating our guests. Like many of our listeners, Natalie and Toby are built environment professionals who have become increasingly driven to change how they work by the dawning realisation that the climate crisis is upon us.

We also discuss whether you can actually have a low-carbon basement.
