It has in recent years become increasingly surrounded by the suburbs of Bideford, and in 2014 only 5 acres of the former parkland remain attached to the house.
The estate is said anciently to have been the property of the famous Grenville family, lords of the Manor of Bideford, and of Stowe, Kilkhampton in Cornwall.
The now "Stucley" family, which had inherited other substantial residences at Hartland Abbey, Affeton and North Molton, sold Moreton House in 1956, after which it was occupied by Grenville College, a private school, which vacated the site in 2009.
The house is a fine example of Georgian architecture and had at one time ornate gardens with two lakes, fountains, waterfalls and formal herbaceous borders.
From their profits they acquired much land near Bideford and eventually by the end of the 18th century their estates almost surrounded the north side of the town from Westleigh to Northam.
