Description
Holmbush is a large castellated mansion built in 1823 for Thomas Broadwood, with the architect being Francis Edwards, although Broadwood is said to have designed the house's plan. The building is constructed of ashlar and has two storeys topped with a castellated parapet. The main front, which faces south-east, features 14 windows and is divided into two sections of different heights. The main section has seven windows, three of which project, and is complemented by octagonal turrets at the corners that include loop lights. The western section also has seven windows but is lower in elevation. The sash windows have dripstones above, and the eastern half of the front retains its glazing bars. The entrance features a doorway with pilasters, a pediment, a semi-circular fanlight, and a recessed door with six fielded panels. The north-west front has 16 windows and includes a three-storey tower with an octagonal turret at the north end and a lower octagonal turret towards the center. There is a classical porch with a pediment, a recessed section without castellation towards the south end, and a projection beyond it. Holmbush is a notable example of a castellated mansion.
