The Burgwin-Wright house is more of a 1770s home with Georgian architecture and colonial style gardens. There's many artifacts from the 18th and 19th century and the two level terraced gardens are gorgeous. The website offers a handy timeline of events if you are into history.
The Latimer house meanwhile is more of an example of upper end life in the 50s. It has 14 room and more than 600 historic objects. This is more of an Italian style architecture and design easily noticed by the arches and hallways, and a division between the formal and informal areas of the home.
