Table Mountain writes the light schedule here
"One street can hold a shaded Victorian sash and a sun-blasted glass box. We measure for the window in front of us, not the suburb's reputation."
The City Bowl sits inside its own micro-geography — Table Mountain, Lion's Head, Signal Hill and Devil's Peak wrap around three sides, and that shapes light before anything else does. Homes on the lower mountain slopes — Higgovale, upper Tamboerskloof, upper Oranjezicht — catch hard, direct sun for most of the day with little relief. Streets deeper in the bowl, or on its shaded side, lose the sun earlier and fight winter damp instead. We measure for which problem is actually yours, not a generic brief.
Wind is the second character in this story. The south-easter Capetonians call the Cape Doctor funnels straight down the mountain's ravines into the upper bowl — Vredehoek and the ridge streets above Kloof Street feel it hardest. Any exterior product here, an awning or a zip screen, gets specified wind-rated and, wherever budget allows, motorised with a wind sensor that retracts it before a gust does the damage for you.
Then there's the building stock itself: Victorian terraces and Edwardian semis with narrow sash windows sit two streets from architect-renovated homes with floor-to-ceiling glass and double-volume voids. One calls for slim aluminium or warm timber venetians that respect the frame; the other calls for a concealed ceiling-recess system and motorisation, because nobody's reaching a hand-crank at four metres. We quote both properly, on the same street if that's what it takes.
Many Bowl addresses are sectional title. If you're on a body corporate, we'll help you check what's allowed on the exterior before anything's ordered — better to ask once than reorder twice.
