The pavilion and summer houses programme at the Serpentine in Hyde Park are great, architecture at its most creative and reminds me of the spatial design course (Bournemouth and Poole College of Art 1990s). I particularly like the sinuous qualities of the pavilion designed by Bjarke Ingels Group (BIG) and the summer house by Asif Khan, and the notion of the loose parts kit by Simon Nicolson.
