During the first lockdown in March 2020, the 20th Century Society started a small project on Instagram asking people to pick their favourite C20 detail. I was thrilled to be asked to contribute and after much thought I decided to pick the iconic precast concrete 'diamonds' of Welbeck Street Car Park as my favourite detail from a twentieth century building. It soon picked up momentum and at the end of the year the project was published in this wonderful book celebrating details from all kinds of architecture and design from all over the world. Being one of the fifty contributors is fantastic. I'm hoping it introduces more people to the wonderful Welbeck design which is sadly now gone and other fabulous designs from this great era of architecture. For more details please visit here .
