The Camden family, descended from the Pratts, built the Dower house (otherwise known as Bayham Old Abbey House), on the estate as the old residence. The new grounds were landscaped by Humphry Repton, who included within his plans the old abbey, which Samuel Hieronymus Grimm had sketched about 1785, emphasising the grand scale and picturesque character of its ivy-clad walls. Some modifications were made to the abbey during this time, memorialised in one of Repton's most complete "Red Books", with the inscription "Application of Gardening and Architecture united, in the formation of a new place".
