Plas Teg is located to the south-east of Leeswood, on a north-east facing slope overlooking the Alun valley. It is notable for the survival of a seventeenth-century courtyard, with gazebo, to one of Wales finest Jacobean houses. The grounds include a walled garden and a replanted lime avenue. The house (nprn 36160) was built by Sir John Trevor (1562-1629), the second son of Sir John Trevor of Trevalyn Hall, in 1610 (nprn 36160). It is doubtful if there was ever a scheme for a park here as family attendance at Plas Teg was fairly sporadic right from the beginning. Long periods were spent at court in London, and Glynde in Sussex became the chief family seat, leaving Plas Teg tenanted or empty for much of its life.

Nineteenth-century drives remain to the north and south of the house, but the lodge, formerly at the north entrance, was demolished when the A541 was widened. To the north-west of the house is a wooded area which has a small ha-ha around it. Some specimen oaks and limes are scattered throughout the area to the south-west, north-west, and south-east of the house. There are also some mature sycamores. Aligned on the north-east front of the house are the remains of a lime avenue stretching to the A541 Mold-Wrexham road. This is shown on a late eighteenth-century estate map, but the present trees are younger, so the avenue has been replanted.

Very little survives of any garden at Plas Teg. An eighteenth-century drawing shows that there was an entrance courtyard on the north-east front of the building with two pavilions/gazebos, one at each outer corner, with a pillared gateway in the centre. The two side walls of the court are shown joined by a wall capped with fretted stonework, in the centre of which, aligned with the front door is a gateway entrance with arch over. The drawing also shows walled enclosures on each side of the gazebos, and to the front. The gazebos, built c.1610, formed an important part of the formal garden layout at Plas Teg. One of the forecourt gazebos survives (23061) and the other was rebuilt in 1996.

The ground behind the house is steeply sloping, and directly behind the house is a stone retaining wall. Immediately to the south of the retaining wall and to the south-east are the remains of a nineteenth-century shrubbery. This area is bound to the north-west and south-east by stone revetted ha-ha. The 1st edition Ordnance Survey map (25") indicates meandering paths and a small pond. A small oval glasshouse, possibly a conservatory, is also shown to the south-east of the house but this does not survive.

The small stone built walled garden, of nineteenth-century date, lies to the south-west of the house on sloping ground above it. The southern end of the garden has a wide and deep stone revetted ditch instead of a wall. A glasshouse once stood on the northwest wall as shown on the 1st edition Ordnance Survey map.

There are two ice-houses at Plas Teg. The first lies to the north-west of the house just north of the site of a pond, now covered by a farm building. It is stone built with a stone vaulted interior. The second lies north-east of the house on the far side of the road (37418).
