Document 4: Balloch Castle: Balloch Castle is an early 19th-century country house situated at the southern tip of Loch Lomond, in West Dunbartonshire, Scotland. Balloch was a property of the Lennox family from the 11th century, and the old castle was built in the 13th century. In the 19th century the estate was purchased by John Buchanan of Ardoch, who demolished the ruins of the old castle and erected the present building. The Tudor Gothic architecture is the work of Robert Lugar. In 1915 Balloch was bought by Glasgow City Corporation, and has been leased by West Dunbartonshire Council since 1975. The estate was designated as a country park in 1980, and since 2002 has been part of Loch Lomond and The Trossachs National Park. Although the house has been periodically used for visitor facilities and council offices, it is now included on the Buildings at Risk Register.

Document 6: Osborne House: Osborne House is a former royal residence in East Cowes, Isle of Wight, United Kingdom. The house was built between 1845 and 1851 for Queen Victoria and Prince Albert as a summer home and rural retreat. Prince Albert designed the house himself in the style of an Italian Renaissance palazzo. The builder was Thomas Cubitt, the London architect and builder whose company built the main façade of Buckingham Palace for the royal couple in 1847. An earlier smaller house on the site was demolished to make way for a new and far larger house, though the original entrance portico survives as the main gateway to the walled garden.
Document 7: McLean's Mansion: McLean's Mansion (originally Holly Lea) is a homestead in Christchurch, New Zealand. The two hectares property is situated between Manchester and Colombo Streets. The mansion was initially known as 'Holly Lea', but later became known as McLean's Mansion after its initial owner. It was the largest wooden residence in New Zealand. The mansion, designed by Robert England, architect of Christchurch, is a fusion of styles of Jacobean architecture and Victorian features, akin to the Mentmore Towers (1852–54) of Sir Joseph Paxton in Buckinghamshire in England. It was built between April 1899 and September 1900. The house is registered as a Category I heritage building by Heritage New Zealand. After the 2011 Christchurch earthquake, the owners applied to demolish the earthquake-damaged buildings, but their request was denied by the heritage body and the courts. In December 2016, the building sold to a trust that will restore it for use as a gallery.
Document 8: Douglas Castle: Douglas Castle was a stronghold of the Douglas family from medieval times to the 20th century. The first castle, erected in the 13th century, was destroyed and replaced several times until the 18th century when a large mansion house was built in its place. This too was demolished in 1938, and today only a single corner tower of the 17th-century castle remains. The castle was the former family seat of the Prime Minister, Sir Alec Douglas-Home. The castle was located around 1 km north-east of the village of Douglas, South Lanarkshire, in south-west Scotland. The remains are protected as a category C listed building.

The main tower house forming the centre of the castle with four floors was built by Andrew, 2nd Lord Gray who was granted the castle in 1490.
Document 11: Burgh Westra: Burgh Westra is a historic home located near Gloucester, Gloucester County, Virginia. Built between 1842-1851 on 3,500 acres, the estate's original design is a two and a half story brick dwelling in the Gothic Revival style. In addition to the main house, the property contains an original dairy, a rebuilt carriage house, guest cottage, gazebo built upon original sketches of Dr Taliaferro, north and south gardens modeled on the original house designs, and a kitchen vegetable garden. Additional dependency foundations of the kitchen, smoke, and ice houses on the property are currently under consideration for reconstruction. Still noticeable in the spring are native daffodils planted around the entrances to originally wooden servant houses on either side of the lane. Aspects of the original fruit and nut orchards are located next to the estate and near the remains of a barn burned by raiding union troops during the Civil War. The extended property contains the original farm managers house and working and fallow fields along the estate's nearly 2-mile long lane. Burgh Westra's floor plan is Design III in "Cottage Residences", by Andrew Jackson Downing. The name "Burgh Westra" comes from the Scottish phrase for "Village of the West", to symbolizing the cottage's location on the North River, Virginia.
Document 12: New Slains Castle: Slains Castle, also known as New Slains Castle to distinguish it from nearby Old Slains Castle, is a ruined castle in Aberdeenshire, Scotland. It overlooks the North Sea from its cliff-top site 1 km east of Cruden Bay. The core of the castle is a 16th-century tower house, built by the 9th Earl of Erroll. Significant reconstruction of the castle has been carried out a number of times, lastly in 1837 when it was rebuilt as a Scots Baronial mansion. At one time it had three extensive gardens, but is now a roofless ruin. Plans to restore the castle have been on hold since 2009.
Document 13: Castle Hill, Filleigh: Castle Hill in the parish of Filleigh in North Devon, is an early Palladian country house situated 3 miles north-west of South Molton and 8 miles south-east of Barnstaple. It was built in 1730 by Hugh Fortescue, 14th Baron Clinton (1696–1751), who was later created in 1751 1st Baron Fortescue and 1st Earl of Clinton, the son of Hugh Fortescue (died 1719), lord of the manor of Filleigh, Weare Giffard, etc., whose family is earliest recorded as residing in the 12th century at the manor of Whympston in the parish of Modbury in South Devon. The Fortescue family became major land owners, influential in British and West Country history. Castle Hill is a rare example in Devon of an 18th-century country mansion "on the grand scale" and forms a highly impressive, unmissable and even dominating sight from the public highway which was, until 1988 when the A361 North Devon Link Road was opened, the main road west to Barnstaple and which appears purposely to meander past to afford the traveller maximum viewing opportunities. The house was substantially reconstructed following a disastrous fire in 1934. It was designated a Grade II* listed building in 1967. The park and gardens are Grade I listed in the National Register of Historic Parks and Gardens. Today the property is leased by Eleanor, Countess of Arran (born 1949), the grand-daughter of Hugh Fortescue, 5th Earl Fortescue (1888–1958). The only historic residence of the Fortescue family now remaining as a seat of the Earls Fortescue is Ebrington Manor in Gloucestershire, a very modest building in comparison to Castle Hill.
Document 14: Kelburn Castle: Kelburn Castle is a large house near Fairlie, North Ayrshire, Scotland. It is the seat of the Earl of Glasgow. Originally built in the thirteenth century (the original keep forms the core of the house) it was remodelled in the sixteenth century. In 1700 the first Earl made further extensions to the house in a manner not unlike a French "château" which is virtually how it appears today. In 1977 the house and grounds opened to the public as a country park. It is one of the oldest castles in Scotland and has been continuously inhabited by the same family for longer than any other. The castle is protected as a category A listed building, while the grounds are included in the Inventory of Gardens and Designed Landscapes in Scotland.
Document 15: Dalmeny House: Dalmeny House is a Gothic revival mansion located in an estate close to Dalmeny on the Firth of Forth, to the north-west of Edinburgh, Scotland. It was designed by William Wilkins, and completed in 1817. Dalmeny House is the home of the Earl and Countess of Rosebery. The house was the first in Scotland to be built in the Tudor Revival style. It provided more comfortable accommodation than the former ancestral residence, Barnbougle Castle, which still stands close by. Dalmeny today remains a private house, although it is open to the public during the summer months. The house is protected as a category A listed building, while the grounds are included in the Inventory of Gardens and Designed Landscapes in Scotland.
