Take in views of London usually reserved for the employees of magazine publishing house IPC Media from the office’s tenth-floor roof garden, a new addition to the Open Garden Squares list of venues. Sleek and contemporary, the Blue Fin garden was designed by London designer Mathew Bell, and features circular lawns, small shrubs, foliage, flowers and trees, all towering over the Thames below. Open Sunday only, 10am to 4pm. See our
