Opponents of plans to expand a mosque in Colliers Wood have warned it would create traffic chaos in the area.

The trust that runs the Dar ul Amaan mosque in Merton High Street - currently a one-storey hall - has submitted plans to replace it with a three-storey building.

Critics said the 19m high structure will draw a bigger congregation than the current building’s 600 worshippers, increasing already serious traffic and parking problems in nearby Laburnum Road - which can become gridlocked during Friday prayers.

But the developer behind the scheme insist it is needed to relieve overcrowding and will not lead to more worshippers at the site.

In a letter opposing the bid, Laburnum Road resident David Tan said: “The proposed mosque would attract a wider following which would increase traffic to an area already overburdened with congestion.”

He also said the building was out of keeping with the area’s architecture, and could overlook neighbours’ gardens.

The plans would involve demolishing the current hall and building a new mosque with prayer rooms on the ground and first floors, and a flat for the imam on the top floor. The new building would also house washing facilities, a library, basement, computer facilities and classrooms to be used by worshippers.

In their submission to Merton Council the developers said the current building was too cramped and worshippers were overflowing into its classrooms and washing areas during Friday prayers. They also said the replacement would improve access for disabled people.

Their plan states: “We are aspiring to create a building which will instill pride and unity in the local community.”

The application was submitted to the council on August 23. The date for the council’s decision on the plans is yet to be decided.
