The talk presented by Phillips and Surface magazine was moderated by Sarah Thornton, author of the international bestseller Seven Days in the Art World and chief correspondent for contemporary art for The Economist. 

With the topic of art and architecture in mind, Charles described the Royal Academy as an ''institution which takes architecture very seriously.'' Saumarez Smith and Alsop discussed the Ai Weiwei exhibition which is currently at The Academy, with Alsop describing how each room ''bleeds into each other but is different.''

Weiwei's exhibition at The RA, from his curation of the exhibition to the installation of the tree sculptures in the courtyard, further explores the relationship between art and architecture and how some artists, Weiwei included, can be perceived as architects.

Discussion went on to the role of the museum, Alsop, who won the RIBA Stirling Prize for Peckham Library, highlighted how he now feels ''too many museums are endless corridors'' and instead of feeling as if one should quickly look at every painting in the entire museum, there should be more space to sit and appreciate a work.

With that in mind, looking arouund, the setting of Phillips Berkeley Square show room is the perfect space to hang the estate of Dr. Frederic S. Brandt and the Contemporary sales.
