The Alphen property was granted to Theunis van Schalkwyk in 1714. Alphen is a square double-storey manor house with a beautiful pediment and exceptional front door. It seems certain that Kirsten built the house in 1765 or a few years later as a double-storey. The remodeling of the house is ascribed to Pieter de Waal c1793.
Alphen is now a restaurant and boutique hotel.
