Plans for a housing development on a London Underground station car park will irreversibly damage “historic” views of an 18th century landscape, campaigners have warned.

The Canons Park Station Group, made up of several residents’ associations, are opposed to plans by Transport for London (TfL) and housing association Catalyst to build 118 new homes on Canons Park Station car park.

Members are concerned the development will block one of Harrow’s few remaining views of a Grade II listed 18th century landscape as seen from the park that gives the area its name.

Sharon Graham, from Friends of Canons Park, said: “These historic sight lines will be completely overpowered by these seven-storey buildings.

“No amount of trees will screen them and it means that, instead of seeing suburbia, what you’ll see is towering blocks.”

The group argued that building three “overbearing, bulky, high-density” seven-storey blocks on the site would have wider negative consequences for the surrounding area.

This, it said, includes increased traffic due to a loss of 100 parking spaces at the car park and the impact on infrastructure based on an influx of new residents.

Campaigners also believe the issues will be exacerbated by similar plans by TfL to redevelop the car park at Stanmore Station, which is one stop away on the Jubilee Line and just over a mile away from Canons Park.

Ms Graham added that increased traffic on the surrounding roads and fewer parking spaces will affect any events held in the park.

She explained that many older visitors rely on driving to the site and, with options reduced or even removed, would not be able to take part.

The Canons Park Station Group says it recognises the need for housing in Harrow but argues this development is inappropriate for this site.

TfL said these plans, alongside those in Stanmore and at Rayners Lane Station car park, are an opportunity to provide “much-needed affordable homes” in the borough.

“Our plans at Canons Park will deliver 100 per cent affordable housing with sustainable links into central London and a new community garden,” said Jonathan Cornelius, head of property development at TfL.

“We’ve engaged extensively with the public over the past year on our plans and will continue to do so.”

He added that 60 commuter spaces would be retained as part of the development, alongside new cycle spaces.

People have until July 14 to have their say on the proposals – these can be submitted via the Harrow Council’s planning portal online or by post addressed to case officer Nabeel Kasmani at Harrow Civic Centre quoting planning reference P/0858/20.
