First, a new wing at Coobe Abbey, then Cloverley Hall and then Kinmel Hall made Nesfield famous and were the principal works of his life. He designed many other buildings, from cottages and lodges to mansions and a number of churches, including the tower at Calverhall church. Nesfield designed Cloverley Hall in 1864 when still only 29 and it was completed in 1868 at a cost, exclusive of decoration, of £60 000. Whilst still building Cloverley he was designing Kinmel Hall and his distinctive “pies” can be seen in the stone frieze work at the top of the clock tower stairs and all over the place at Kinmel.
John Pemberton Heywood had no children and the Hall passed to a nephew. It was such a large house that it became difficult to maintain, particularly after the First World War when fewer people were prepared to return to a life in service. With all the rooms in the building heated by coal fires there were a minimum of twenty five servants required to look after the old building. The original main wing was five storeys high, as high as the present clock tower, with a footprint area covering approximately 450ft x 400ft. The original Great Hall room was 55ft long, 30ft wide and 27ft high.
