Guelph Ontario Homes: Set in Stone


Have you ever thought about how the geology of our natural landscape impact an area's architecture and design?

A good example is the use of limestone as a construction material throughout Southwestern Ontario. Here limestone originates from shallow ocean marine sediments in Paleozoic times3, where the calcitic rocks became dolomitic from percolating magnesium3.

Today, the impact of Ontario’s geology can be seen in Guelph’s unique and fascinating streetscapes when, during the second half of the 1800s builders began constructing limestone homes.

Not only was the stone readily available, but it was softer than other materials, making it easy to quarry and carve2.

Characterized by their amber beige colour, limestone houses have a distinct and striking aesthetic.




Woolwich Street has a series of cottage-style limestone houses. The house shown in the above picture was constructed in 1866 and is located at 348 Woolwich Street.

A common characteristic among limestone houses are their thick, well insulated walls. The home shown above is located at 22-26 Oxford Street and has walls that are 3-feet-thick1!

The President’s House, created for the Principal of the Ontario Agricultural College, is another fine example of a stone house in Guelph.

Its Gothic Revival/Italianate architecture is indicative of a larger trend that was occurring throughout Ontario in the late 19th century.

Interesting fact: The President’s House originally stood where University of Guelph’s Creelman dining hall now stands.

The entire building was moved across the street in 1912 across the street4. The movers “ jacked up the house and transported it … with furniture and dishes still in place”4.
