As many cottages along the lakefront were being demolished, in 1980, it was suggested that Guy House (a farmhouse, dating to c. 1845), could be restored as it possessed historic character.

It was constructed by an early settler named Samuel Phillips and sold to James Odgers Guy, its most prominent resident, in 1861.

[12] The house was built in the style of a Regency cottage, and it is typical of a Victorian era home as several architectural elements include limestone from Kingston, Ontario and a wood-shingled roof.

[16][17] Robinson House contains different exhibits which highlight the role Oshawa and the surrounding area had during the Victorian era and the turn of the 20th century.

[18] In both cases, pottery shards, evidence of settlement and migration, as well as cultivation techniques were discovered, and artefacts from these excavations are displayed.

The exhibit shows the traditional carrying route, discusses the study of archaeology, and highlights the Indigenous community today.

This exhibit connects visitors with the past, embraces the present Indigenous community, and builds towards a spirit of reconciliation and partnership.

[19] The exhibit contains for viewing: a study (where Thomas Henry tended to his duties as a harbourmaster, minister and farmer), a parlour for entertaining guests, a dining hall, a kitchen and the master bedroom.

The Drive Shed complements the exhibit in Henry House by displaying period carriages, buggies and other large artifacts.

[21] The museum occasionally showcases local culture and history with temporary rotating exhibits on a wide array of topics.
