Burges died in 1881 after catching a severe chill during a site visit to the castle. His brother-in-law, the architect Richard Pullan, took over the commission and delegated most of the work to Frame, who directed the work on the interior until its completion in 1891. Bute and his wife Gwendolen were consulted over the details of the interior decoration; replica family portraits based on those at Cardiff were commissioned to hang on the walls. Clark approved of the result, commenting in 1884 that the restoration was in "excellent taste". An oratory originally built on the roof of the Well Tower was removed before 1891 but in other respects the completed castle was left unaltered.
