Statement of Cultural Heritage Value or Interest


Design and Physical Value

The Guess House has design and physical value as a representative example of a Tudor Revival house with Craftsman style architectural influences. The house was built around 1910 and includes characteristics of Tudor Revival design such as: exposed eaves, recessed entry, a brick first storey with a rough-clad and timbered second and third (half) storey, diamond- and rectangular-patterned leaded-glass casement windows, an asymmetrical façade, and a multi-sloped roof made with multiple heights and dormers on each side. The lakestone knee wall along Douglas Avenue supports the Arts & Crafts style character of the property. This house is a unique and elaborate example of popular buildings styles in in Ontario in the 1910s. 

Historical and Associative Value

The Guess House has cultural heritage value for its direct associations with the development of the local residential area known as ‘Brantwood’, an early 20th century subdivision of Oakville. It was one of the earliest buildings constructed in the Brantwood subdivision and was used as an impressive example of the type of architecture that was being promoted in the area by its developers. The house still retains exterior heritage aspects that have lent to the neighbourhood’s character over the last 100 years and its presence contributes to the relatively intact historic development of Brantwood.

Contextual Value

The subject property has contextual value because it supports and maintains the historical residential character of the Brantwood neighbourhood. It is physically, functionally, visually, and historically linked to the surrounding residential neighbourhood and places the Brantwood area’s origins in a specific timeframe. The house was built as an early representation of what the community could be and remains a significant marker within the area’s streetscape.
