Islington Council initially said the project would be completed by March 31, but has now admitted construction is taking longer than anticipated.
Melissa Blissett, who lives in neighbouring Noble Yard, said: “The construction work has taken an extraordinarily long time, it’s been done incredibly inefficiently.

Melissa also voiced concerns about planned restrictions to most traffic in Charlton Place from 8.15am to 9.15pm and 3pm to 3.45pm.

Karen, whose father set up the Camden Passage antiques markets in the 1950s, said many businesses rely on deliveries and would be severely impacted by the traffic restrictions.
She added: “The antiques markets have diminished, which is why I’m trying my best to keep my section open.
“I haven’t increased rent…
