New lodges, namely Ruperra Park Lodge, East Lodge and West Lodge and Ironbridge Cottage were built in the Victorian era. The Iron Bridge, now listed, had been built in 1826 to take the new carriage way from the Castle through Coed Craig Ruperra and across the Rhymney River to Lower Machen Church where the family and their servants attended Sunday services.

By the end of the century the buildings at Ruperra were in need of repair. The stable block had been destroyed by

fire in 1895. After the death of Colonel Frederick Morgan in 1909, his son Courtenay embarked on a programme of refurbishment to include a new east entrance porch, new stables, a new power house fitted with duplicate steam-driven generators, dynamos and boilers and a new reservoir and pump house in the deer park. The brew house, laundry and dairy range built in the 1840s, were converted to accommodate the valets, footmen, chauffeurs and garden staff.
