The reconstruction of Castell Coch was delayed until 1875, because of the demands of work at Cardiff Castle and an unfounded concern by the Marquess's trustees that he was facing bankruptcy. On commencement, the Kitchen Tower, Hall Block and shell wall were rebuilt first, followed by the Well Tower and the Gatehouse, and the Keep Tower last. Burges's drawings for the proposed rebuilding survive at the Bute seat of Mount Stuart. The drawings were supplemented by a large number of wooden and plaster models, from smaller pieces to full-size models of furniture.
