In 1887, a year before his election to Parliament, Thomas took the lease of the house, where he lived the life of a country squire, riding to hounds and breeding prize Hereford cattle.

He bought the house in 1900 and acquired the neighbouring Pencoed estate shortly before his death, the purchase making Thomas the largest landowner in Monmouthshire after Lord Tredegar.

[10] A £115m renewal project called Glan Llyn, led by St. Modwen Properties Limited, is transforming the former steel-producing part of the Llanwern steelworks site.

Started in 2004, the masterplan envisages 34 acres (14 ha) of employment-generating accommodation hosting 6,000 jobs, 4,000 new dwellings, community facilities and open space including three new lakes.
