Start with the room and the time
“Sunny apartment” is too broad to compare two homes. Write down the practical question instead: will the kitchen receive morning sun, will the balcony be usable after work, or will the desk be bright without glare? Different rooms can face different directions and have very different obstructions.
Use three kinds of evidence
- Orientation and surroundings: mark windows on a floor plan and locate nearby buildings. Confirm the plan's north arrow rather than assuming the top is north.
- Seasonal geometry: compare the relevant local times in summer and winter. A clear summer afternoon does not establish winter sunlight.
- Observation: visit the actual room, balcony or garden and record where the sun reaches. Note the date, time and cloud conditions.
Outside the tropics, equator-facing windows generally have more opportunity for winter sun: south in the Northern Hemisphere and north in the Southern Hemisphere. East and west commonly favour morning and afternoon respectively. In tropical locations, use the actual seasonal sun path. See the Australian government's orientation guidance for the role of climate.
What a building-shadow map can tell you
Coffee in the Sun helps you explore how mapped neighbouring buildings may obstruct sunlight at a chosen date and time. That is useful for spotting questions before a viewing: does the tower opposite matter in winter, or is the courtyard open toward the afternoon sun?
The model is not a simulation of the apartment interior or a particular window on a particular floor. It does not establish legal rights to light, compliance with daylight standards or the effect of a future development. Trees, awnings, fences and terrain are not included, and building-data quality varies. For a purchase dependent on sunlight or development risk, obtain property-specific professional advice.
Questions to ask during the viewing
- Which rooms receive direct sun, and at what times and seasons?
- Are there dated photographs from winter as well as summer?
- Do balcony slabs, trees or neighbouring walls block the windows?
- How does the home handle glare and summer heat?
- Are any proposed developments relevant to the outlook? Verify through the local planning authority.
Ask to view at a different time if the light is a deciding factor. Compare homes using the same criteria rather than accepting a sunny photograph as a year-round description.
Separate light quality from a price claim
There is no universal percentage by which sunlight raises a home's value. Local sales, layout, condition and buyers' preferences all matter. Our sunlight and property value guide explains how to discuss the issue without inventing a premium.
Save the sunlight viewing checklist and use it consistently for every property you compare.
