" CHRONOLOGY OF THE HISTORIC DEVELOPMENT
The site of the present Salomons estate was once within the Manor of Southborough (Borough of South), one of four boroughs forming the Manor of Tunbridge that was given to Richard de Fitzgilbert in the C11 in recognition of his part in the Norman Conquest (Hasted). Prior to this, although there is evidence of prehistoric activity around Southborough and use of the land as pasture for pigs, the area was sparsely populated until the mid-C14 (CAA). From the C16, the water from the River Medway and its tributaries was used to power mills for iron smelting and, in the C18, for gunpowder manufacture. From the mid-C18 maps also identify a number of farms, as much of the Medway valley was ‘very fertile and good fatting land’ (Hasted). These include a Salmon (sometimes Salmons) Farm between Ashurst and Groombridge, which may have been associated with the Levy Salomons family, who owned a property in nearby Frant at that time (Andrews, Dury and Herbert; Hasted; Greenwood).
In 1829, Levy’s son, David, a London financier and fighter for Anglo-Jewish emancipation, bought a small country house in Southborough called Broom Hill. He commissioned the architect Decimus Burton, who was already working on the development of the Calverley Estate, Tunbridge Wells, to advise on early alterations (listed building description). The 1840 Tithe Map records the property (Broom Hill Villa) as a holding of some 8ha comprising a house, gardens and pleasure grounds with an orchard, meadow and woods. During the subsequent twenty years Salomons, who was made a baronet in 1869, substantially enlarged the house and landscaped the grounds, and added two lodges and a kitchen garden (1st edn OS map). An 1872 photograph depicts a raised terrace around the house, which was laid out with intricate parterre beds, from which descended lawns richly planted with trees.
In 1873, on Sir David’s death, his nephew, David Lionel Salomons, inherited both his property and his title. From then until World War One, David Lionel, a scientist and engineer, continued to enlarge the house and gardens, laid out a new entrance drive and built a lodge. He also added a water tower, workshops, garages and a scientific theatre with a photographic studio, dark rooms and a chemical laboratory. A substantial stable block was built in 1894 and the adjoining kitchen garden was extended to accommodate a new range of glass houses (3rd edn OS map; Gardeners’ Chronicle).
David LioneI had four daughters and one son, David Reginald, who was killed in 1915 in World War One. In 1925, on her father’s death, his last surviving daughter, Vera Bryce Salomons, inherited, although her mother, Lady Julia, remained at Broom Hill until her death (Kelly 1934). In 1938 Vera gave Broom Hill to Kent County Council to be used as a public institution and its name was changed to David Salomons House. The property was requisitioned by the army during World War Two, but from 1948, after the introduction of the National Health Service, it was transferred to the Ministry of Health and used as a convalescent home for women until 1971. In 1975, David Salomons House became the Regional Conference and Training Centre for the South East Thames Regional Health Authority and in the 1980s two accommodation blocks were built in the kitchen garden. The property was renamed Salomons Centre in 1993.
In 1996, Salomons Centre became the property of Canterbury Christ Church College (from 2005, Canterbury Christ Church University). It continues to function as a conference and training centre with a museum open to the public. The property remains in single corporate ownership.
SITE DESCRIPTION
LOCATION, AREA, BOUNDARIES, LANDFORM, SETTING
Salomons is set among the undulating landscape of the High Weald and is characterised by its hanging woodlands and rocky outcrops. The house stands back from the road in the northern section of a site that descends steeply from the north to the south-west. There are fine distant views to the south and the west to Birchett’s, Speldhurst and Shadwell Woods and the well-timbered grounds of Bentham Hill House estate are about 75m to its north. The 15ha site adjoins residential areas on the western outskirts of Southborough and is approximately 4km north-west of Royal Tunbridge Wells and 6.5km south-west of Tonbridge. The A26 (London to Royal Tunbridge Wells road) is 1.5km due east. The site is bordered to the north by Etherington Hill and the Speldhurst Road, and to the east by Broomhill Road. The boundaries on the west and south are formed, respectively, by Southlands Farm and Mill Farm.
ENTRANCES AND APPROACHES
Salomons is entered from the west side of Broomhill Road, some 100m south-west from its junction with Speldhurst Road, along a tarmacadam-surfaced drive between a pair of 1.5m high stone piers with stone cappings. A third similar pier on their north side forms a pedestrian entrance. Rusticated stone walls extend from the piers along the property boundary and enclose it from the roads on its northern and eastern sides. On the south side of the drive’s entrance is a two-storey lodge with attic (Oak Lodge, listed grade II) designed in Olde English Revival style (listed building description). It is constructed of ashlar with a timber-framed first floor and a tiled roof with a chimney stack displaying the date 1894 with the Salomons family crest (listed building description). The lodge frontage has a hipped weather porch with stone lions on its tiled roof, which is supported by stone columns. There is a single-storey extension on its west end.
From the entrance, the tarmacadum-surfaced drive descends steeply in a westerly direction for approximately 350m, running between lawns studded with mature beech, Scots pine and oak trees and with views south across the valley, to arrive at a forecourt on the east entrance front of the house. Two hundred metres west of the entrance, a fork from the drive’s north side serves a stable block then continues in a north-westerly direction for 150m to reach the northern end of the forecourt. The forecourt (c.20m x 35m) is partly enclosed on its north side by a projecting wing of the house and on its south and east sides by low, dressed stone walls. It is now used as a car park. Visitor parking provision (since the 1980s) extends some 200m east from the house along the south side of the main drive.
A second drive, now serving as an exit route from the north side of the forecourt, enters the site at a second lodge (North Lodge) on Speldhurst Road. Built in the mid-C19 also in Olde English Revival style, North Lodge (listed grade II) is a one-and-half-storey building with a timber-framed first floor decorated with a central quatrefoil and a steeply pitched, fish-scale-tiled roof. Its side elevations are partly tile-hung (listed building description).
Until the late C19 improvements by David Lionel Salomons, this was the main entrance and approach to the house (Tithe Map; 1st edn OS map).
A third drive, also now serving as an exit route, enters the site 140m south-west of Oak Lodge on Broomhill Road and runs for some 250m in a north-westerly direction to a gap in the east wall of the forecourt. This drive, probably designed as a service drive, was in place by 1862 but a lodge at its entrance has since been demolished.
PRINCIPAL BUILDINGS
When built in the 1820s, the house at Salomons (listed grade II), was a cottage named Broom Hill. It was extended by Decimus Burton (1800-81) in 1829 in an Italianate villa style and enlarged again (architects unknown) during the C19 and early C20 centuries (listed building description).
It is now a house of irregular and complex form, but is mainly constructed in three storeys. It is built with Tunbridge Wells ashlar blocks with a slate roof. The L-shaped east front and the south, garden front both have a stone parapet and balustrade, the balustrade dating from 1854. There are porticos with colonnades on the south and west fronts. A wing on the north end of the building was added by 1897 to house David Lionel Salomons’s science theatre and garage block and extended in 1902 and 1913 (date on the building). Some 10m to the east of the house is a C19 red brick building built as electrical workshops in 1882. These have been renovated and continue to be used as workshops by the grounds staff.
Ten metres north-east of the house is a water tower (listed grade II) built in 1876 on an outcrop of Tunbridge Wells rock with caves constructed underneath. The round tower of four storeys is built of stock brick with a band of red brick marking each storey. It has a crenellated parapet, a clock face and arrow-slit windows (listed building description). Water was pumped up to the tower from a local stream by a hydraulic ram (located 250m south-west of the house) and
provided the supply for the house and the estate. Extending eastwards from the tower’s east side is a 2m high wall which forms part of the south wall of a kitchen garden. The wall also has a crenellated parapet and arrow slit openings and with imitation towers built into it.
One hundred and fifty metres to the east of the house is a stable block and coach house (listed grade II*) designed by the architect William Barnsley Hughes and completed in 1894 (Salomons Museum). It is laid out around a stable yard in the style of a miniature French C16 chateau of red brick with stone dressings (listed building description). The entrance is on the south side through a pair of 3m high wrought iron gates. These are hung from a 6m high brick-and-stone arch set centrally in a 3m high brick wall with stone dressings. The two-storey, red brick coach house stands on the north side of the stable yard, flanked on either side with single-storey stables with lofts above, also in red brick. The coach house has been converted to a dining room (Runcie Court) and the stables to offices.
GARDENS AND PLEASURE GROUNDS
The ornamental gardens lie on the south and west sides of the house and comprise terraced gardens with informal lawns, lakes, shrubberies and woodland walks on steeply descending land. The south and west fronts open onto a broad, stone flag terrace supported by a deep, stone retaining wall. The terrace, with sloping lawns below and from which there are panoramic views over the gardens and to the surrounding countryside, is enclosed by 200mm high rounded stone blocks with regular square stone piers and urn finials. A conservatory has recently been built at the northern end of the west front and serves as a dining room.
From the south front, flights of stone steps (some in need of repair) descend to two, broad, grass terraces, one below the other with shrub borders at the base of their grassy banks. Below the terraces, the lawn then falls steeply to a small lake some 60m south-east of the house. It is spanned by a wooden bridge and is set within a recently planted area of evergreen shrubs and young trees. Seventy metres south-west of the house is a second, larger lake with an island, on which there is an Ionic temple, placed there in 1994. A wooden deck on the lake’s east bank stands on the site of a C19 boat house shown on maps until the 1950s.
From the south-west corner of the top, flagged, terrace, a long flight of shallow steps provides direct access to the lake and winding gravel walks around it, one now partly a cinder track. To the south and west of the lake there are further walks through hanging woods on the site boundary. These paths were laid out during Sir David’s lifetime and are shown on maps from 1862, later being described as ‘the delightful Wood Walk’ (Garden Life). A few metres to the east of the lake is a level grassed area (25m x 50m), possibly the site of the ‘extra tennis court … with rose beds all around’ mentioned in 1906 (3rd edn OS map; Garden Life).To the south of this is another grassed area (c.80m x 80m) used for sports activities.
KITCHEN GARDEN
A C19 kitchen garden (c.120m x 70m) is sited a few metres east of the house and is entered from the drive at North Lodge between a pair of 2m high brick piers (the gates now gone). The garden’s brick walls, 2-3m in height, now contain two L-shaped accommodation blocks and a car park, built on levelled ground in, respectively, the western and northern sections. The remaining south-facing, sloping section is laid to lawn with some old fruit trees surviving. A smaller kitchen garden (70m x 70m) is shown on maps from 1862 when it was divided into quarters with perimeter paths and a fountain (1st edn OS map). A large glass house range is shown along the northern wall and in the south-west corner, on the site of the present water tower.
The kitchen garden was extended eastwards when plans for the construction of the stable block were made in 1890 and by 1891 a range of Crompton & Fawkes glass houses had been installed along the north wall (Gardeners’ Chronicle). A published interview with the head gardener Mr Roberts and his garden notes for 1890/91 describe his horticultural expertise, particularly in fruit growing. The kitchen garden continued in production until at least 1955 when six gardeners were employed and surplus produce was sold (gardener’s notes). The glass houses were demolished in the 1980s, but wall marks and shelf supports indicate their position. A dipping pool and parts of the 1891 path layout also survive (Gardeners’ Chronicle)." (1)
