The MP for Hornsey and Wood Green has expressed concerns over plans to build a new supermarket, car park and 400 flats.

Lynne Featherstone has submitted a response to the planning application by Sainsbury’s and the developer St James to redevelop the old depot site in Hornsey High Road.

The application was submitted last year and will be discussed by Haringey Council – who will make the final decision on the whether to approve it – on January 20.

In the response, the Liberal Democrat MP outlined concerns about the impact of the development of local businesses, increased traffic and the quality of housing.

Ms Featherstone said: “Nobody wants this site to remain derelict, but the consequences of over-development or pushing ahead with plans against the will and advice of local residents could harm our local area.

“Concerns remain about the impact on local traders, the increased traffic, the quality of housing and the increased demand on local schools and GPs a surge in population will cause.

“These concerns and more are outlined in detail in my response.

“These considerations must be addressed before local residents and I can fully support the planned development.”

The MP held a public meeting to discuss the development in November, and together with the Haringey Lib Dems, asked thousands of residents for their views about the plans.

Residents’ views arising from the meeting and survey have been used to inform the response.

The Haringey Independent is awaiting a comment from Sainsbury's and St James.
