Residents at the Embassy Gardens development in southwest London claim its controversial Sky Pool is too cold to be used in winter, despite heating costs of £450 a day.
There are calls for the transparent swimming pool, which is suspended 35 metres in the air between two buildings, to be closed during the colder months to save money and energy.
"We are livid," said one Embassy Gardens leaseholder, who did not wish to be named.
"The outside temperature has obviously dropped, but the Sky Pool is still open to residents and currently uncovered. We're basically heating the sky."
Residents claim the Sky Pool is barely being used now the temperature has dropped
Dezeen has heard from three separate residents that the Sky Pool is now only being used by a small handful of people, though the developer of Embassy Gardens, Ballymore, said that the pool area was accessed more than 100 times in the last week. "It costs roughly £450 a day to heat that pool before adding the costs for two staff including a security guard," the resident added.
"It's also only being used now by a handful of residents because the water's actually quite cold."
Ballymore's running cost estimates for the Sky Pool put the total figure at £720,000 for 2021 including £164,250 for heating, with residents footing the bill via service charges.
