Rev Richard and his descendants slowly accumulated land in Hanbury, including the manor that Edward Vernon bought in 1630.

However, it was Thomas, through his successful legal practice, who added most to the estates, which, by the time of his successor Bowater Vernon, amounted to nearly 8,000 acres (3,200 ha).

The 18th-century Worcestershire historian Treadway Nash, in his Collections for the History of Worcestershire, wrote “Here is a large handsome house built by Counsellor Vernon about the year 1710 when a bad style of architecture prevailed; many windows and doors, rooms small, many closets, few arched cellars, large stables and offices in full view, are marks of that time”.

On the south side there had been large formal gardens, clearly shown in Dougharty's perspective drawing contained in the estate maps of the 1730s, and Cecil swept all these away (including the farm buildings in front of the Hall) and landscaped the park in the fashion of the time – he would have had contact with Capability Brown when being brought up by his uncle 9th Earl of Exeter at Burghley House.

Emma died in 1818 and left her second cousin, Thomas Shrawley Vernon (1759–1825), as the heir to her estate after the death of her husband John Phillips.

Sir George led an unhappy life, separating from his wife Doris, and spending his last 10 years living with his secretary and companion Ruth Powick, who later changed her name by deed poll to Vernon.

During this time the agricultural depression led to a reduction in rental income, and Hanbury Hall suffered a lack of care.

Negotiations led to the National Trust having the reversion, and after making essential repairs on Lady Vernon's death, the hall was let to tenants and opened to the public on a restricted basis.

It has red Flemish bond ashlar brickwork, with a tiled hipped roof, and large brick chimney stacks.

The Grade II* listed[7] Long Gallery pavilion dates from circa 1701, and is built in Queen Anne style.

The one-story rectangular building has red Flemish bond ashlar brickwork, with a tiled hip roof behind a parapet.

The main elevation faces south, and has nine sets of windows, of which the central three are moved forward and are topped with a pediment, containing a carved fruit basket along with flowers and wreaths.
