The Xstrata Treetop Walk at the Royal Botanic Gardens, Kew
A chance to walk amongst the tree canopy and to enjoy views across the gardens (including the Pagoda and the Temperate House, undergoing a multi-million pound refurbishment) and landscape beyond – Sunday was a clear day and Wembley Stadium, The Shard and swathes of West London were clearly visible. A superb design and brilliant choice of materials – rusting metal echoing the trees themselves.
