THREE of the borough's landmarks have been added to a list of heritage sites in danger of deterioration.
A Victorian house in Harrow on the Hill and two 18th-century walls in Stanmore are now on English Heritage's 'at risk' register, released last Wednesday.
Chalgrove, a Grade II listed detached house in Peterborough Road, is 'slowly decaying with no agreed solution'.
The building, thought to have been built in the early 1890s, is also described by English Heritage as 'one of a group of important, elegant and distinct Arts and Crafts houses by Arnold Mitchell'. At present it is boarded up and on the market.
The two 18th-century walls on the list run along the east side of Stanmore Hill. They are also Grade II listed.
They have been badly affected by weathering and are at risk of falling apart as a result of gradual decay.
Harrow Heritage Trust closely monitors the status of sites on the at risk register.
Martin Verden, chairman of the group, said: "For buildings or sites to be listed is a really big deal and it is important for the heritage and history of Harrow that we try to keep them in good conditions.
"It is a shame that more sites are being put on the list and that is why we try to do all we can to help restore sites before they get to this stage. We offer grants and free advice on external repairs that need to be done to listed buildings."
The three new sites join a list of other places of interest in Harrow. Among them are the Grade II listed Rayners pub and The Hermitage, a two-storey cottage in Kenton Lane, both of which have been unoccupied for some time.
The pub in Rayners Lane, which is noted for its 'high architectural quality', has not been altered since the 1930s, but it was closed in 2006, since when it has been a target for vandals.
Colin Mitchell, 38, of Alexandra Avenue, said: "It's a shame that nothing has been done with the site. It has been empty for quite some time now and it is getting worse. Because of its location, it is a bit of a target for vandalism but hopefully someone will step in to do something with it."
The Hermitage, one of the oldest sites on the list, retains some 16th-century features but is at risk of significant deterioration because of a problem with damp.
Also listed are the 17th-century Cannons Farm barn, in Hereford Gardens, Pinner, a brick kiln in Common Road, Stanmore, and the entrance to Bentley Priory, also in Stanmore.
The list is put together to help monitor sites in need of repair as a priority.
