Its functional design with classical influences, high quality materials and construction, for example:
- the three-storey, square, tapered form of the tower with its classical tripartite division into base, tapered tower and capital, surmounted by an octagonal lantern;
- the attached gable-roofed dwelling that is well integrated with the tower;
- the regular spacing and vertical alignment of the tower’s window openings and the door pediment;
