Work started on the new Harlaxton Manor in 1832, 10 years after Gregory Gregory inherited the old manor. In the years between inheriting the old manor and beginning construction of the new, he toured Europe collecting objects, read as much as he could find on architecture, and travelled across England seeking inspiration from various Elizabethan manors. Gregory Gregory spent an estimated £10,000 per year on construction. The central tower was up by 1836, and the house was substantially completed by 1844. The old manor in Harlaxton Village was left in a terrible state from neglect and was consequently torn down in 1850. According to census records Gregory Gregory moved into the new Harlaxton Manor by 1851, but continued to embellish the house until his death in 1854. Despite his death, the house was not officially complete until 1855.
