A long, low building set into a hillside of wild grasses

Hospitality · Stellenbosch, South Africa · 2021

Kestrel Winery

Pressed into the hillside, like the vines around it.

Overview

Kestrel Winery is built into the slope, so the cellars stay cool without machinery. From the road you see only a long, low line of glass and a meadow roof that flowers in spring.

The tasting room looks across the valley to the Helderberg. Charred oak, cast concrete and rammed earth from the excavation give the building the colours of the land it came out of.

Materials

Made of few things.

Three materials, chosen at the source and left to age. Nothing is painted to look like something else.

  • Charred timber boards with a deep black grain

    Charred Oak

    Scorched the old Japanese way, oiled, then left alone. The char is the weatherproofing, and it deepens with every winter.

  • Fair-faced concrete with tie holes and formwork joints

    Fair-faced Concrete

    Cast once, in timber formwork we draw ourselves. The tie holes stay: they are how you read the pour.

  • Low-iron glass reflecting trees and warm interior light

    Low-iron Glass

    Without the green cast of ordinary glass, so the landscape reads true from edge to edge.
