"In 1895 "Glenhope" was built by John Spier Heron and was described at the time as making a wonderful improvement to the district.

The gracious two-storied red brick residence, with a tile roof and tower, is a landmark on Castle Hill Road and has been owned and occupied by the Salisbury family for some seventy years.

Containing spacious rooms, high ceilings and a cellar, it is surrounded by large lawns, flower beds, trees, fernery and at one time had a tennis court and is so designed that the main living rooms and tower take advantage of the sweeping views....... "

From "The Settlers of West Pennant Hills" by Gwen Millhouse

"Glenhope is a rare local example of the Federation Queen Anne style of large residence ..... and provides a fine local example of residential design, materials and finishes of the late nineteenth century both externally and internally" from 'Glenhope Conservation Management Plan' by Graham Edds 2000.

Glenhope was known as "Castlefield" when it was built in 1895 and in fact was built by Mrs Edith Pape Heron, a widow and mother of John, and was constructed from 140,000 bricks which were brought from the brickworks at Eastwood by train and horse drawn carts.

John Heron became a noted orchardist in the area and was President of the Castle Hill and Hills District Agricultural Society in 1901. He had earlier served as Secretary and President of the Pennant Hills Progress Association. By 1898 John Heron had 50 acres of land of which 40 acres was under fruit trees and he was advertising plums, apples, pears, peaches and nectarines for sale.

In 1912 the property was purchased by Francis Salisbury who owned the Portmanteau Manufacturing Company in Sydney. The Salisbury family expanded the holding to about 132 acres of mostly orchard. The house portion was sold in 1954 to Mr G.F.O. Mullen who held it until 1969 when Bill Salisbury, nephew of Francis, bought it. Bill Salisbury sold Glenhope and the remaining 1.5 acres to the present owners in 2000.

The drawing room and entry lobby are recognised in the conservation Report as 'having significant historical value' and have been featured in "Victorian Splendour" by Suzanne Forge. More detailed information is available on the bookshelves at Glenhope.
