Revised plans to re-build a house on the edge of Hampstead Heath - which would see a quiet footpath being used to transport building materials - have been submitted to Camden Council.

The owners of the Water House in Millfield Lane, Highgate, want to demolish the existing building and construct a new two-story home with a basement and separate chalet.

As part of the proposals lorries could move along Millfield Lane up to eight times a day - a small, quiet track used by walkers and swimmers to access the Heath and its ponds.

The planning application says there has been “extensive local consultation” about the revised scheme to respond to concerns about the size of the building and measures have been put in place to minimise disruption.

But the City of London Corporation, which runs Hampstead Heath, said lorry movements along Millfield Lane is an area of “grave concern”.

Superintendent Simon Lee, said: “This complex application has only recently been logged by Camden Council and the City of London Corporation has asked for an extension as consultation is being undertaken during the summer recess.

“Construction vehicles movements along the unmade part of Millfield Lane remains an area of great concern.

“The City Corporation will defend the Heath’s natural landscape and sense of countryside against any built development adjacent to, or visible from, the Heath which may be deemed threatening to this sanctuary.”

The architects and planning associates working on the project were unavailable for comment.

Michael Hammerson from the Highgate Society said; “If it’s going to have any impact on the Heath or any impact on people using the path then we’re going to have to take that up.”
