A four-face clock was donated to the town by William Potts, a Leeds clockmaker, in memory of his late father who had lived in Darlington. It was installed in the tower of Park Houselvii. The clock tower had originally been built for viewing the park but this function was now lost. The new clock, however, enhanced the character of the building as a main focal point.

A cottage, which became known as Park House, was built for the resident park keeper. It had been planned in 1851 but insufficient money was available at that time. It included a viewing tower and a refreshment room. It was and still is regarded as the main focal point of the entire park. The building was constructed with a type of white brick that is nicknamed the “Pease” brick. These are featured in many Darlington buildings that were built between approximately 1850 and 1875. Unfortunately, the brickwork on the main faces of the house has since been painted over.
