Dormers? Mid-century...perhaps...modern...not so much. While the mid-century saw many modern-style houses constructed, many Ottawa builders had at least one design in their portfolio with traditional dormers windows. I have to say that I have always been fond of dormer windows. My first apartment was on the top floor of a 3 storey walk-up and had dormers in all of the rooms. Also, my first house also had a dormer window in the master bedroom. There is something very cosy about a room with slanted ceilings. Aesthetically, a house with dormers has a lower profile in comparison to a two-storey facade, so it looks better next to a 1-storey bungalow - which many mid-century neighbourhoods are filled with. Below are a few selected plans for houses built in the mid-century in Ottawa that have dormer windows: This large design manages to have 5 bedrooms under the slanted second floor roof line, including the large master bedroom. c. 1969, Skyline.
