Bungalows are one of Ottawa's most common and beloved housing types, found extensively in neighbourhoods like Alta Vista, Carlington, Westboro, Vanier, and throughout the suburbs built in the 1950s through 1970s. These single-storey homes offer accessible living, generous lot sizes, and strong neighbourhood character, but many are now 50 to 70 years old and in need of modernization. Bungalow renovations in Ottawa range from interior refreshes and open concept conversions to dramatic second-storey additions that double the living space. Whether you love your bungalow's single-floor convenience ...
Bungalows offer unique renovation opportunities due to their single-storey structure, typically large lots, and accessible roof and foundation systems.
Adding a second storey is the most dramatic bungalow renovation, doubling or tripling the living space while maintaining the existing lot footprint. In Ottawa neighbourhoods where lot sizes are generous but bungalow footprints are modest at 800 to 1,200 square feet, a second storey adds 3 to 4 bedro...
Many Ottawa bungalows were built with small, closed-off rooms that do not suit modern living. Removing walls between the kitchen, dining room, and living room creates a spacious, light-filled main floor. Because bungalow roof loads are often carried by exterior walls, many interior walls are non-loa...

Bungalows present unique design opportunities that capitalize on their single-storey layout, roof structure, and typically generous lot coverage.
One of the most dramatic bungalow upgrades is opening up the ceiling to expose the roof structure, creating vaulted or cathedral ceilings that make rooms feel dramatically larger. In many Ottawa bungalows, the attic space above flat ceilings contains 4 to 6 feet of unused volume. Removing the ceilin...
Bungalows have roof access from every room, making skylights and sun tunnels easy and effective additions. Skylights in kitchens, bathrooms, and hallways flood interior spaces with natural light. Enlarging existing windows or adding new ones on exterior walls is simpler in a single-storey structure....
Bungalows are naturally suited to accessible and aging-in-place design since all primary living spaces are on one level. Wider doorways, roll-in showers, lower counter heights, lever-style handles, and zero-threshold transitions between rooms accommodate wheelchair access and mobility aids. Main-flo...

Ottawa's zoning bylaws limit building height, lot coverage, and setbacks from property lines. Second-storey additions must comply with height restrictions, which vary by zone but typically allow residential buildings of 9 to 11 metres. Increased lot coverage from rear or side additions must stay wit...
