By the end of the eighteenth century, the Earls of Harewood controlled one of the greatest of all West Indian interests (Table 7.1). But the Lascelles were reluctant planters: the family had never aspired to become large-scale, absentee owners of sugar estates. Indeed, between the laying of Harewood House's foundation stone in 1759 to the time Robert Adam's and John Carr's masterpiece was ready for occupation in 1771, neither Edwin Lascelles nor his brother Daniel possessed a single slave or acre in the West Indies.

The family's lack of ownership of West Indian estates during the 1760s and early 1770s is extraordinary given the acquisition of plantations on Barbados by Edward Lascelles in 1648 and William Lascelles in 1684. Barbadian merchants never divorced themselves from land completely despite a general retreat from plantation ownership during the later seventeenth century. Characteristically, the island's wealthiest traders combined commercial careers with ownership of at least a single property. Possession of a sugar estate complemented the activities of slave trading and sugar exporting, while landownership raised the prospect of nomination to the Barbados Council, election to the Assembly, or judicial appointment to one of the island's courts.
