Twenty-three people who measure before they draw

Studio Halden is owned by the people who work in it. We started in a shared office in Oslo in 2014 with one client and a bus timetable that nobody could read.

How the studio runs

We take six to eight projects a year, which is the number that lets every partner review every project every week.

Designers and engineers sit on the same teams from the first week. Research isn't a phase that ends; the person who timed the journeys in week one is still on the project when the signs go up.

We don't pitch for free and we don't do spec work. When a client asks for ideas before signing, we sell them a three-week audit instead, and half the time that audit is the most useful thing we do for them.

100%

Owned by the people who work here: six partners, and an employee trust that holds 40% for everyone else after their first year.

Why Rotterdam

Half our clients were already a train ride from Rotterdam. Opening a studio there cut our flights by two thirds and gave us a test wall big enough for full-size station signs.
