The Serpentine Pavilion, designed by Herzog & de Meuron and Ai Weiwei, must be one of the quietest's spaces in London. Enveloped in cork, this take on the archaeological dig makes me want to spend day after day sketching there, and listening to strangely dampened sounds. I wonder how the Park Night events are going to feel this year:  www.serpentinegallery.org/park_nights/
