340 Watson Avenue
Lot 196 and PT Lot 195, Plan 113; Town of Oakville

Statement of cultural heritage value or interest 


Design value or physical value

The subject house has design and physical value as a representative example of a Colonial Revival house. The house was built in 1929 with elements of Colonial Revival design such as: side gabled roof with symmetrical façade; brick English bond pattern; boxed cornice return with dentil detailing at the roofline and dormer roof line; brick quoins on the corners; central entrance with small stone porch with sidelights and fanlight surrounding wood panelled door; door surround with radiating square brick voussoirs; multi-paned windows with brick lintel with keystones and stone sills; wooden shutters; and a bay window on the north elevation. The building has been well maintained with many of its original features intact, making it a good representative example of the Colonial Revival style.

Historical value or associative value

The home has cultural heritage value for its direct associations with the development of the local residential area known as ‘Brantwood’. The property 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 Brantwood neighbourhood. Developed in the early 1900s, this subdivision was designed with large lots and mature trees, and was sold to city dwellers as a secluded, beautiful, and modern neighbourhood in which to construct their own cottage or stately home.

Contextual value

The subject property has contextual value because it supports and maintains the historical residential character of the Brantwood neighbourhood. It was one of the earliest buildings in the neighbourhood and still retains exterior heritage aspects that have lent to the neighbourhood’s character over the last 100 years. 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 one of the earliest built on the block and is one of the few heritage buildings on the block as many of the others were built post-1950. This makes its presence even more important for the protection of Brantwood’s historic character. The home is a prominent building on the street. 

Description of heritage attributes

Key heritage attributes of the property at 340 Watson that exemplify its cultural heritage value, as they relate to the historic house, include:
  • The massing and form of the gable-roofed two-and-a-half storey building with shed dormer and the hip-roofed two-storey rear wing;
  • Symmetrical façade with central door; 
  • Flared eaves with boxed cornice return with dentil-decorated frieze and wooden soffits on main roof;
  • Shed dormer’s dentil frieze decoration and wooden shingles;
  • Red brick English bond with header bricks every five rows, as well as quoins on the corners; 
  • Brick window lintels with keystones;
  • Entryway sidelights with multi-paned wood windows, wooden fanlight window and wood panelled front door;
  • Front door arched header with radiating square brick voussoirs;
  • Fenestration of the south, east, and north elevations, including the bay window on the south elevation; and
  • The use of multi-paned sash and casement windows.

Any objection to this designation must be filed no later than October 13, 2023.  Objections should be directed to the Town Clerk, 1225 Trafalgar Road, Oakville, Ontario L6H 0H3.
