An estate plan of 1798 showing the construction of the park and gardens at Buscot by Edward Loveden
 
Parkland work commenced in earnest as the mansion works were nearing completion in 1782. Park paling was completed during the summer of 1782, when deer were bought. Underground drainage was carried out in the spring of 1782, followed by the digging of the fishpond in the summer, and tree planting in the autumn. The sward was sown in the spring of 1783. These initial works comprised 120 acres of parkland pasture, 5 acres of water, 23 acres of plantation and 5 acres of kitchen garden, plus one acre of shrubbery around the house. The layout made best use of the local topography, and its simple arrangement created a setting for the mansion that echoed the English Landscape fashion of the period.
    
Between 1786 and 1792, Loveden spent the considerable sum of £60,000 in order to expand the estate by purchasing numerous local landholdings. In 1788 he acquired the neighbouring Throckmorton estate, and so became the owner of the Farn Hill land on which his house was built, and by 1798 he owned most of Buscot parish, as well as parts of Eaton Hastings, Coxwell and Faringdon. To the east of the house he created a new 20-acre lake fed by an existing stream; to the west he extended the deer park and to the south he took more heathland and pasture into the park, adding a further 107 acres overall. The lake was a particular feature, creating long views across the water from the north front of the house to an eye-catching bridge that closed the eastern end of the lake.
