Almost 8,000 users of Instagram, which recently passed the half a billion active-user mark, have so far hit the like button on a picture of the stunning spiral staircase and glass lift in Rigby & Rigby’s £45m St Saviour’s Church development in Knightsbridge. Influential Instagrammer architecture_hunter posted the picture, with fellow architects and design enthusiasts giving it the thumbs up. Said one architect: “Seeing it first time (is) like having a vacuum capsule lift in the centre of a Spiral Staircase…amazing work!! Well done.”
