What is the best way to add natural light to a kitchen extension in Ottawa?

A kitchen extension without enough natural light can feel like a basement, and in Ottawa, where winter days are short and often grey from November through March, getting daylight into the new space is a real quality-of-life decision, not just an aesthetic one. There are several reliable ways to do it, and the best results usually come from combining two or three of them.

The most impactful option is usually large sliding or folding patio doors on the south- or west-facing wall of the extension. South-facing glass captures the most low winter sun, while a roof overhang or awning helps keep the room from overheating on hot summer afternoons. Modern high-performance glazing with low-E coatings helps keep heating bills manageable even with a lot of glass, so ask your contractor or window supplier to compare the energy ratings of the units they propose.

Skylights and roof lanterns are another strong approach, particularly if the extension has a flat or low-pitched roof. Overhead glazing is especially useful in a single-storey extension where neighbouring houses or fences block side light. The key in Ottawa is detailing: freeze-thaw cycles and ice damming are hard on roof penetrations, so ask how the contractor will handle flashing and membrane around each skylight, and who warranties that work.

Clerestory windows, set high on the wall where the extension meets the existing house, are a clever compromise. They bring in light without taking away wall space for upper cabinets, which matters in a kitchen layout.

Glazing also affects your permit drawings. Your designer will show window and door schedules that meet the Ontario Building Code's light and ventilation requirements, and walls close to a property line can face limits on how much glass is allowed. Plan the light strategy early, and let your designer confirm what is permitted on each wall before you fall in love with a layout.

An often-overlooked idea is an interior glazed wall or transom between the extension and the existing house. It borrows light from adjacent rooms and connects the spaces visually. Light-coloured counters and a reflective backsplash help modest windows go further.

For winters that regularly drop well below -20°C, choose windows and skylights with strong energy performance, such as triple-pane units with low-E coatings and gas fill, and ask for itemized quotes so you can see what each glazing choice costs.
