Garden walls, steps and terracing at Glen Usk

The garden at Glen Usk features an architectural framework that includes a wall enclosing the garden to the north, situated between the house and stable yard, which may be part of the original garden layout. There is a secondary wall that defines a terrace parallel to the east side of the house, and a terraced walkway that runs along the south side of the house, extending eastward. All these walls are made of sandstone rubble with plain copings. The boundary wall to the north is marked by a series of urn finials, while the eastern terrace wall has piers with ball finials flanking the steps, along with terminal piers topped with urn finials. The south terrace features flagstone paving and a high retaining wall, with a parapet that has open-work sections that step out to create alcoves overlooking the tennis court. There are flights of stone steps connecting each level of the terrace. At the level of the tennis court, the wall is enhanced by pilasters on either side of a prominent central section, with a cornice below the parapet. There is a central alcove with voussoirs around a doorway, accompanied by flanking lights. Similar doorways can be found in the outer bays, although the one to the east is blocked. Repairs to the stone-flagged terraces and steps were underway as of January 2005.
