- Window orientation shapes how your home feels and what you pay on energy bills. North windows bring in winter warmth, east ones add gentle morning light, west windows need shading from harsh afternoon sun, and south windows give soft, even light. Size, placement, shading, glazing, and ventilation all matter too
You probably didn’t realize it, but the way your windows face can completely change how your home feels. It decides whether you’re cosy in winter, sweltering in summer, or stuck paying high energy bills all year round.
The funny thing is, many buyers and even some builders overlook this ultra-critical aspect. Here’s how to get window orientation right so your home works with nature, not against it.
Why Window Direction Matters
Windows are more than just glass panels you look through to see the outside world. They set the tone for comfort, light, warmth, and even your power bills.
- A well-placed window catches winter sunlight and keeps heating costs down, especially if you opt for double glazing or triple glazed windows.
- Good orientation stops the summer sun from baking your living room.
- Natural light makes rooms feel bigger and more welcoming.
- Windows also guide airflow, giving you a fresher, cooler home.
Think of orientation like a free climate control system. Ignore it, and you could end up with a house that feels like a freezer in July and a sauna in January.
North-Facing Windows
In southern Australia, north-facing windows are the gold standard. They bring in plenty of natural warmth in winter and can be shaded easily in summer.
- They catch low winter sun, which acts like natural heating.
- In summer, the sun is higher in the sky, so simple shading keeps the heat out.
- Overhangs or eaves work best with a ratio of about 1 to 2. That means for every metre of window height, you want a two-metre overhang.
- These windows suit living rooms, kitchens, or stairwells where light and warmth are most welcome.
- Using double-glazing or low-emissivity glass makes them even more efficient.
- Best for: Southern cities with cold winters like Melbourne, Hobart, Adelaide, Canberra. Also useful in Perth and Sydney for winter warmth.
It’s no exaggeration when we say that a good set of north-facing windows pays for itself over time in lower energy bills and year-round comfort.
East-Facing Windows
East-facing windows are all about gentle morning light.
- Perfect for bedrooms if you like waking up with the sun.
- Kitchens and breakfast areas benefit from morning warmth without getting stuffy.
- The sun is softer in the east, so it’s less likely to overheat rooms.
- A simple blind or curtain gives you control if you prefer a slower start to the day.
- Best for: Warmer climates like Brisbane and Darwin, where softer morning light is welcome and less heat enters in the afternoon. Also handy in Sydney and Perth kitchens.
They won’t heat your house in winter the way north-facing windows do, but they add a cheery start to your mornings.
West-Facing Windows
West-facing windows can be tricky in Australia’s climate. The afternoon sun is harsh and can turn a room into an oven if not handled well.
- Keep west-facing windows smaller where possible.
Shade them with external blinds, pergolas, or even strategically planted trees. - If you must have large west-facing windows, double-glazing and heavy curtains help.
- Best suited for spaces you don’t spend much time in during the hottest part of the day, like garages or laundries.
- Worst for: Hotter regions like Perth, Adelaide, Brisbane, and Darwin where afternoon heat is strongest. Manageable in cooler areas like Hobart or Melbourne with shading.
West-facing windows can be tricky. Without shade, they overheat, but with smart design, they stay cool and inviting.
South-Facing Windows
South-facing windows get the least direct sun in most parts of Australia.
- They provide soft, even light throughout the day.
- Perfect for bathrooms, home offices, or laundries where consistent light matters more than warmth.
- Great for reducing glare and overheating in summer.
- They’re not ideal for living rooms, as they won’t give you much winter warmth.
- Best for: Hotter parts of Australia like Darwin, Brisbane, and Perth where avoiding extra heat is more important. Less useful in cooler southern regions like Hobart or Melbourne.
South windows won’t do the heavy lifting for heating, but they’rereliable for balanced lighting.
Size and Placement Count Too
The direction matters, but so does the size and where you put your windows.
- Larger windows on the north side are perfect for soaking up winter sun.
- Keep west-facing windows small unless they are well-shaded.
- High clerestory windows bring in light while keeping privacy.
- Low-level windows lose more heat, so energy-efficient glass is worth it.
- Always place windows in rooms where people spend the most time, so you get the most benefit from natural light.
Think of window placement like furniture arrangement. Get it wrong and it feels awkward. Get it right and everything flows smoothly.
Shading and Glazing
Even the best window orientation needs backup. Shading and glazing help control light and heat.
- Eaves, pergolas, and verandas can block summer sun while letting winter sun through.
- Shading should be designed for your location’s seasonal sun angles.
- Double-glazed or low-emissivity glass keeps your home warmer in winter and cooler in summer.
- External shading, like awnings or louvres, is more effective than relying on curtains inside.
Ventilation and Breezes
Windows aren’t only about light. They also shape airflow in your home.
- Placing windows on opposite sides allows cross-ventilation.
- Cross-breezes can cool your home naturally in summer.
- Proper ventilation reduces the need for air conditioning.
- It also keeps indoor air fresh, which is better for health.
The right orientation turns your windows into a natural fan system, saving you money and keeping you comfortable.
Don’t Forget the View
Orientation is about sunlight and heat, but the view matters just as much.
- If you have a great view, design your windows to make the most of it.
- Decks, large glass doors, and bigger windows can all enhance the outlook.
- Replacing old windows with modern, clear designs can improve both the view and the property’s value.
A million-dollar view through a poorly placed window is such a missed opportunity. Get the design right, and it adds both joy and resale value.
