The property includes a country house, built on the remains of a priory, 98 acres (400,000 m2) of gardens and landscaped grounds, and a working mill.

He made extensive additions to the house to accommodate his collection of furniture, art, books and objets d'art and landscaped the grounds.

[3] The walls of the chapter house were incorporated into the main part of the domestic dwelling, with the calefactory or monks' day room to the north left as an outbuilding.

The brothers had inherited a fortune from their maternal grandfather, an American oil baron Henry Huttleston Rogers, and could live a life of leisure devoting themselves to owning and breeding racehorses, collecting art and creating gardens.

The work was done by architect Sidney Parvin from the London firm of interior designers Turner Lord, and featured in a 1930 edition of Country Life.

[8]: 26 Henry moved out when he married in 1932, leaving his older brother, by then Lord Fairhaven (having been given the barony that was about to be bestowed on his father, Urban H. Broughton, when he died) as the last private owner of Anglesey Abbey.

Lord Fairhaven made extensive additions to the house to provide room for his rapidly expanding collection of books, paintings, tapestries, clocks, furniture and objets d'art.

[4]: 27 Lord Fairhaven converted the grounds of Anglesey Abbey, which had been largely meadow and grazing land when the brothers bought the property, into an 18th-century style park with avenues of trees, flower gardens, statuary and ornaments.

[8]: 11  Lord Fairhaven's collection includes furniture, paintings and sculptures, clocks, tapestries, books, and objets d'art and, according to the author of a guide to Anglesey Abbey, expresses "an eclectic taste and refreshing disregard for fashion".

[4] Furniture includes an Italian Renaissance refectory table in the dining room, chairs embroidered by Lord Fairhaven's mother in the living room, a white japanned Chippendale dressing table that once belonged to actor David Garrick in one of the bedrooms, and bookshelves made from the piles of John Rennie's Waterloo Bridge in the library.

There are paintings by John Constable, Thomas Gainsborough (a rare seascape), Richard Parkes Bonington, Edwin Landseer and the Pether family as well as a series of Tudor portrait panels.

[8]: 33–4 The 98 acres (400,000 m2) of Grade II* listed landscaped grounds at Anglesey Abbey are divided into several avenues, walks, vistas, and gardens, with classical statuary and flowerbeds.

He describes how huge areas of sky and mown grass were used to balance symmetrical planting and how Lord Fairhaven used the trees and shrubs to make groups of contrasting colour and foliage.

[14] In 2013 Richard Todd, head gardener at Anglesey Abbey since 1974, received the British Empire Medal for his years of service to the trust and national heritage.

Seasonal attractions include the winter lights festival, snowdrop and daffodil tours in spring, and summer outdoor cinema.
