As part of this assessment of the significance of Caverswall Castle, a full inventory of all historic features, fixtures & fittings within the house and the garden pavilions has been undertaken to gain an insight into its development. For a more comprehensive understanding of the development of the house, the building would require a full measured survey. The only historic floor plans date from 1893 and relate to W. E. Bowers works to improve the water supply to and within the building. These floor plans are schematic and useful to show the earlier layout of the rooms but they are not an accurate measured survey and there are a number of draughting errors.

As to be expected with a house of this age, there are a number of phases of remodelling evident as fashions changed over the decades.

The property changed hands many times over the centuries, more than most houses of this importance. As the property changed hands, a number of owners have wanted to make their mark on the building, although there have also been long periods when the house was either neglected or used by those with little means to carry out major works of improvement, such as the Benedictine Nuns in the nineteenth century and the Missionary Sisters in the twentieth century.

The main phases that are evident within the building are; early seventeenth century, early eighteenth century and two phases of remodelling in the second half of the nineteenth century.
