In the 1840s the 1st Baron Mostyn commissioned architect Ambrose Poynter to remodel the house, which was carried out mainly in 1846–47 in a Jacobethan style inspired by the pre-existing building.

[3] Porth Mawr is a former Tudor gatehouse block to the south west of the house which dates from 1570.

Ornamental entrance gates leading to the house were designed in early 18th-century Baroque style by the Chester architect John Douglas and constructed by James Swindley in 1896.

[12] On the wider estate, listed structures include an icehouse,[13] the walled garden,[14] and a gamekeeper's cottage.
