Offices for the newly merged Newcastle Breweries and Scottish Brewers (Scottish and Newcastle) built between 1964 and 1965 to designs by brewery architect C.P. Wakefield-Brand. The building was formally opened on 2 December 1965 by Sir William McEwan Younger Bt. D.S.O. The ground floor housed the main entrances, foyer, reception and stores. Above this were offices to either side of a curved spinal corridor, formed of demountable wood partitions, fixed partitions and glazed screens. At either end of the spinal corridor there are service blocks comprising lifts, stairs and cloakrooms. The board room, director's suite and flat occupied the 9th floor. There was a caretaker's flat on the top (11th) floor. In 2005 the brewery closed and has since been demolished. This office block is the only survivor of the complex and is being converted into a hotel (2010). The building has 11 storeys plus basement. It has a reinforced concrete frame between columns with metal windows over buff brickwork panels. The main elevations are supported on sculptured piloti columns and beams clad in plain white mosaic. There is a balcony at 10th floor level formed of columns faced in black granite slabs. The end elevations are clad in brickwork panels with a central vertical window slot. In plan the building has a gently curved, concave front elevation. To either side of the main entrance are black marble slabs which record the foundation and opening dates. Fixtures and fittings have mostly been removed. In the service blocks a few original toilet doors with metal plates survive. Both original stairs with terrazzo flooring survives. The upper two floors retain some later wooden cupboards and a caretaker's flat. Pevsner describes the building as 'more interesting than most of its kind because it curves gently'.

Row of houses with feature porches and chimneys. Stone lintels and cills, prominent date stone of 1895, and simple polychrome brickwork.

During this period Sir Henry Liddell (1644-1723), son of Thomas Liddell (d. 1619), 3rd Baronet and politician was the owner of Ravensworth. Correspondence between Henry and his sons John Bright (nee Liddell - he assumed the name of his grandfather Sir John Bright of Badworth, Yorkshire) and George, refer to Ravensworth Castle's poor condition and debate the pros and cons both of modifications and replacing the 'old castle' with a new house. The final decision appears to have been building a new front towards the gardens, modifying the east range and including a Palladian façade. Sir Henry died before works were complete. His grandson Henry Liddell (1708-1784), 4th Baronet, succeeded him. An engraving by Buck c.1728 - the first surviving picture of Ravensworth - shows the castle from the east as a Palladian villa overlooking an enclosed court flanked by the two medieval towers (HER 106), linked by the curtain wall. The architect is unknown. The villa was extended in the mid 18th century, probably to designs of James Paine (1716-1789). An engraving by Bailey c.1787 shows that Paine had added two flanking bays. That to the north incorporated one of the medieval towers. Additional chimneys suggest interior changes. The engraving shows the remains of an Elizabethan range and a further medieval tower to the rear (west). At this time five medieval towers may have survived, Sketches by S.H. Grimm c.1780s include an oblique view looking east. Sir Henry died in 1784 without a male heir. The barony passed to his nephew Henry George Liddell of Newton Hall (1749-1791), 5th Baronet. He brought a herd of reindeer to Ravensworth from Lapland, which Thomas Bewick illustrated. Sir Henry commissioned a map of the estate from John Fryer. It shows a central block around a rectangular courtyard with two wings extending from the south-west and north-east, and additional buildings to the east. The Palladian villa and Paine extensions look like Bailey's c.1787 engraving, but the rear (west) looks very different, suggesting that the medieval and Elizabethan ranges may have been replaced, or it may be a discrepancy between the plans and engravings. No above-ground evidence of the Palladian villa survives but there may be some below the Nash house (HER 8183) footprint or main courtyard. In 1787 it was described as 'small, but neat, without much ornament' but with 'elegantly fitted up' south-facing rooms.

Range of workshops north of the stable block gardens, adjoining the north tower. Small and single storey. Appear to be part of the original design of the stable block. They incorporate the same stone columns that surround the two possible drying yards to the immediate south. In the north-east corner of the workshops there are the fittings for a laundry or feed copper. The basin from the copper survives but is not in-situ. The laundry or copper is served by a flue and firebox on the east wall.

The woodland is situated on steeply sloping ground west of the castle complex. It comprises plantations known as Fugarfield Wood, Hill Head Wood, High Park Wood, Blackman's Wood and Silverhill Wood. A straight track runs through the woodland, dividing it from the arboretum to the east. The woodland is leased to and managed by the Forestry Commission. It mainly comprises mixed plantation woodlands on the site of ancient semi-natural woodland. The tree cover includes remnants of 19th century sycamore, oak and beech and more recent 20th century Norway spruce, Scot's pine and yew. Overhead power lines run through the centre of the woods in an unplanted wayleave. There is more diverse ground cover associated with woodland rides - including species indicative of ancient woodland - ransoms, wood sorrel, bluebell, wood avens, cleavers, wood cranesbill, foxglove and bracken. More diverse grassland rides are present within the woodland with species including ladies smock, lesser stitchwort, bugle, buttercup, cow parsley and hogweed. Mature trees (beech and yew) are also present on the fringes of the woodland along the line of the carriage drive. Rhododendrons are present on the edge of the woodland.

A clump of mature sycamore trees, known as The Peak, on the hill that protrudes to the east of Hill Head Wood. Forms a striking focal point when viewed from the castle complex.

Stone wall and piers at the entrance to Cross Lane.

An unusually deep ditch in the north-west corner of South Park. May have been part of the medieval park.

Picturesque Victorian cottage. Located on the east edge of the walled garden, partly enclosed by the red brick boundary wall with ornate stone caps on brick piers. In a good state of repair. There are cedars of Lebanon in the garden. The Journal of Horticulture & Cottage Gardener of 15 Nov 1877, page 384, said 'his house is contiguous to the garden, and is unison with the magnitude of the establishment'. It was approached through two pairs of cedars which framed the path from the garden. To the north of the cottage is Castle Gardens, a modern detached house that is privately owned.

The pleasure grounds were developed after the landscaped park, probably in association with improvements to the castle in the early 19th century. Located north of the castle, linking the castle to the walled garden, and flowed north and west from the turning circle at the north entrance to the castle. By 1861 a pair of ponds had been created in an area planted with trees and interesected by numerous walks. The walks were described in the Gardeners Magazine of 1834 as being 'bordered with the finer kind of shrubs'. The Journal of Horticulture & Cottage Gardener in 1877 described the spectacular rhododendrons some 20 feet in diameter. Near the lake yew trees were trimmed into a 'sugar loaf' shape and reached 20 feet high. There are still two ponds (HER 12020) within the woodland and fenced enclosures for pheasants. Some remanants of the pleasure grounds are still evident, such as two stone gate piers on a track between the ponds (may relate to the 18th century garden), and a number of specimen trees. There is a large cedar of Lebanon, a fine hornbeam next to the east fish pond and another cedar of Lebanon on the island of the west fish pond. Possible remains of a footbridge to the island may be present beneath vegetation. Parts of the pleasure grounds were subsequently planted with conifers.
