East London tower block residents described their flats as “like living in an oven” after the building reached sweltering temperatures, forcing them to leave their homes to take breaks from the heat.Problems with scorching temperatures inside Leaside Lock flats have been ongoing since last year, when one resident found the heat so unbearable they plastered a sign which read “DO NOT BUY THESE FLATS. TOO HOT” in their window.The Standard spoke to residents in the new-build development in Tower Hamlets a year on, who said extreme temperatures in the Summer remain an unresolved issue, making it “challenging” to stay in the building.Residents will deal with scorching temperatures of up to 34C this week during London’s fourth heatwave.
