Bay windows—typically three panels with a larger centre pane flanked by two operable units—add depth, daylight, and crisp architectural definition. They’re a familiar sight on Toronto semis and Scarborough side-splits. To keep them warm and dry through freeze–thaw, we specify proper structural support, an insulated seat, and careful flashing at the roof and side returns. For heritage façades, we scale mullions to the rhythm of the street so the original character stays intact while comfort improves.
They shine in living rooms and dining nooks where light and curb appeal matter—think side streets off Roncesvalles, near Trinity Bellwoods, and older brick homes in Cabbagetown.
Design notes: use a centre picture pane for views with casement or double-hung flankers for ventilation; include an insulated seat with moisture management; and match exterior cladding and trim to existing profiles.
