Stand on a River Club patio at four in the afternoon and the brief writes itself: the glass that gives you the course also catches the lowest, hottest sun of the day. On the highveld, a kilometre and a half above sea level, that sun carries real bite — and it lands on exactly the wall you least want to cover up.
Open ground changes the wind, too. A fairway boundary gives a gust a clean run at the house that a walled garden never would. So anything we fix outside — awning, external venetian, zip screen — is specified with a sensor that pulls it in before a storm front arrives, not a hopeful glance at the sky.
