The Soane building is probably the world's first purpose-built art gallery. This is a case of right first time. The famous sequence of arched spaces in Soane's interior is a shrine for Gallery designers, inspiring amongst others Louis Kahn in his Kimball Art Museum, Robert Venturi at the Sainsbury Wing of the National Gallery in London and Richard Meyer at the Getty Museum in Los Angeles. It is revered for practical and aesthetic reasons. Its roof-lanterns diffuse natural daylight, creating an even 'wash' of light over the walls, ideal for viewing paintings. The simple arches and smooth coved vaults provide interest without fuss. It is an architecture of harmonious lines rather than lavish decoration, and its elegant simplicity has never gone out of fashion.
