Inside what was once a 19th century water tower, Swiss-Italian architect Monica Donati has created an unusual apartment, which, though small (it's 80 square metres in size) more than makes up for the lack of space with its spectacular 360° views across Paris. To the east, the Eiffel Tower. To the south, the Champs de Mars. To the west, the Invalides, the Pantheon and Notre Dame. To the north, the Grand Palais, Arc de Triomphe and Montmartre. Here Monica lives happily in her fantastic space perched up in the clouds, away from the noise of everyday life.
