Buildings that age well.
Datum is an architecture and urbanism studio in Cape Town. We make considered, durable buildings — houses, cultural spaces and public work — built to outlast their trends.
Four disciplines,
one studio.
We build for the long now — not the next trend.
Every project begins with the site, the light and the people who will use it. We design in concrete, timber and stone, detailing for decades of wear rather than the launch photograph.
Selected work,
2020 — 2024.

A small studio,
built around the detail.
Datum is a team of nine architects and urbanists working from a converted warehouse in Salt River.
We take on a handful of projects a year, so every drawing gets our attention — from the masterplan down to the door handle.
- Concept to completion
- In-house detailing & joinery
- Heritage & sustainability consulting
