Pwll-y-wrach Georgian mansion, dating from c.1770, is located to the east of Colwinston in gently rolling countryside (nprn 19787). Gardens lie mainly to the south and west of the house on ground sloping gently down to the south. They fall into two main areas: the informal garden to the south and the walled garden to the west (700156).

The drive from the west enters the garden on its south side onto a terrace forecourt with wall and parapet and with a central flight of steps down to a sloping lawn. This is bounded by a curving ha-ha giving an open view south from the house, framed either side of the lawn by large beech, sycamore and horse chestnut trees. To the south of the ha-ha a lawn slopes gently up to the drive, and beyond a further lawn rises gently to an oak paling fence on the garden boundary: Beyond the garden is a gently rising field, deliberately splayed, with a few isolated oaks and the view framed by belts of trees along the east and west sides. A pair of small stone pavilions flank the house on the east and west (310365-6), the former within a small lawned area enclosed by walls and hedges. A larger walled enclosure, with the former stable block, lies on the east.

The house and garden were once set in parkland. To the east of the house it was planted with scattered trees and through it passed a partially tree-lined second drive, off the A48. This drive is now disused and reduced to a farm track and the rudimentary park is farmland.
