Collishaw House

The Collishaw house is valued as a unique example of Victorian architecture in a rural setting and for its association with first owners, successful farmers William and Elizabeth Collishaw. The Collishaws were among the first settlers in the area, homesteading on Mud Bay Road in 1887. They started what became a thriving vegetable farm, and William Collishaw became known locally as the Onion King for his farm's prodigious crop. The construction of this large farmhouse, following the reception of a Crown Grant in 1889, indicates the growth of the Collishaw's farming ventures.

The Collishaw House is also important for its association with the development of agriculture in the Kensington Prairie area. Rich alluvial soil attracted farmers at an early date in Surrey's settlement, although at the time there was always danger of the Nicomekl River flooding its banks. Valued for its age and importance to the development of Surrey, this property is one of the oldest continuously operated farms, and the third oldest house, in Surrey.

The house is also significant for its Queen Anne style architecture, unusually ornate for a farmhouse of this era. The steep roof and turret make the house architecturally unique within Surrey's farming communities and conveys a sense of prominence through its architectural details and recognizable massing and form. The scale of the house is typical in relation to the surrounding landscape at its time of construction. The house would have been a prominent feature on the flat farming prairie.
