Datum — Architecture Practice
Selected Works / 2009–2026
Architecture measured in decades.
Datum is a Rotterdam and Copenhagen practice working across cultural, civic, and private commissions. We begin every project with rigorous analysis and a single organising idea — and we remain until it is built.

The Practice
01 / Approach
Every commission is a problem of organisation before it is a problem of form. We resolve the plan first — how people move, how light arrives, how a building meets the ground — and let the architecture follow from that logic rather than precede it.
01
Analysis before form
We read the site, the brief, and the institution before we draw a single line.
02
Material honesty
Structure and surface are the same decision; nothing is applied to disguise what a building is.
03
Built to endure
We design for maintenance, adaptation, and the long life a public building deserves.
