01/ Architecture studio, Zurich

Shaped by material and light.

Ferro is an architecture studio of eighteen people. We design houses, workplaces and public buildings in concrete, timber and stone, and stay with every project until the keys change hands.

02/ The studio

Architecture that outlasts its brief.

We start with the site, the budget and the way you want to live or work. Then we draw slowly, test with models and choose materials that age well. The result is quiet buildings that are easy to run and hard to tire of.

Daylight first

Every plan starts with a sun study, so rooms are placed where the light is.

Honest materials

Concrete, timber, lime and stone, chosen to be left visible and to last.

One partner, start to finish

The partner at your first meeting is the one on site at handover.

Built, not just drawn

64 buildings completed, each one visited a year after the clients moved in.

04/ Services

Five ways we work with you.

Most clients come to us for a whole building. Some need a careful interior, a second life for an old structure or an honest answer about what a site can hold.

Architecture

New buildings from first sketch to handover, with one partner responsible for the whole job.

05/ Process

From first visit to handover.

Four stages, one team. You always know what we are working on, what it will cost and what we need from you next.

Brief and site

We walk the site with you, read the planning rules and listen. Then we write the brief back to you in one page, with a first cost range.

  • Site visit and survey review

  • Planning constraints in plain language

  • One page brief and first cost range

Usually 3 to 5 weeks

06/ Clients

In their own words.

Harrow Lane House, 2024

They drew the house around the way we actually live. Two winters in, it still surprises us how the light moves through it.

07/ Questions

Before we start.

The questions we hear most in a first meeting. If yours is not here, ask us directly. A partner answers every enquiry.

How early should we involve an architect?

Before you buy the site, if you can. A short feasibility study tells you what the plot allows, what it will cost to build and where the risks are.
