The focus is a 1:25 scale model illustrating modernisation of an old hall house through the centuries and displaying what is under the surface of typical buildings of the age. There is a map showing ancient houses in Harleston and explains how they were made and their position in the town.

The model was created for Heritage Open Days 2025 by Colin Brown. There is an associated trail of Hall houses in Harleston: https://www.harlestonhistoricalsociety.org.uk/hall-houses
