Buildings for people who plan to stay.

Atelier Sorne is eleven architects in Zürich. Since 2012 we have built housing, schools and places of work across Switzerland and southern Germany, for cooperatives, municipalities and owners who think in decades.

Projects at a time, at most

Six projects at a time. Never more.

It is the only way all eleven of us can know every building. Five are in hand. The sixth place opens in spring 2027.

Five kinds of building. One way of working.

We take the commissions where a building is used every day by people who did not choose its architect.

Approach · three principles, seven stages

01

Build less, better

The most sustainable square metre is the one you do not build. Every commission starts with what can stay, what can be shared and what can be left out.

Lime plaster, second coat

02

Honest structure

What holds the building up is what you see. Timber reads as timber, concrete as concrete, and nothing is clad to look like something else.

Hand-moulded brick, flush lime joint

03

Fifty-year rooms

We draw rooms that can change their use without changing their walls: generous heights, daylight from two sides, services you can reach.

Larch window frame after three winters

Seven stages, numbered like floors. You can stop after any of them.

0Stage 0 of 6

Feasibility

Should you build at all? We test the site, the planning rules and the money, and we tell you when the honest answer is no.

You receive
Feasibility study, cost range, three options including doing nothing
Usually takes
4–8 weeks
1Stage 1 of 6

Brief

Together we write down what the building has to do for the next fifty years: who uses it, what may change, what must not.

You receive
Written brief, room schedule, budget frame
Usually takes
4–6 weeks
2Stage 2 of 6

Concept design

Models before drawings. Three ways of answering the brief, built in card at 1:200 and tested against cost.

You receive
Concept model, sketch plans, first estimate
Usually takes
8–12 weeks
3Stage 3 of 6

Design and permit

The chosen concept becomes a building: structure, materials, energy, fire. We submit the permit and answer the neighbours.

You receive
Permit drawings, structural concept, estimate within ten percent
Usually takes
4–6 months
4Stage 4 of 6

Tender

Every detail is drawn before a single offer is requested, so prices can be compared and nothing is discovered on site.

You receive
Construction drawings, tender documents, contractor proposals
Usually takes
3–5 months
5Stage 5 of 6

Construction

We are on site every week, usually more. Each Friday you get one page: progress, cost, open decisions.

You receive
Site supervision, weekly report, cost control
Usually takes
12–24 months
6Stage 6 of 6

Handover

Keys, manuals and a walk through the building with everyone who will use it. We come back after the first winter and again after two years.

You receive
As-built drawings, care manual, two return visits
Usually takes
Two years of aftercare

Studio

One room, eleven desks, a model workshop.

We work on the second floor of a former print shop in Zürich West. Partners draw. Everyone goes to site. Every project has a card model you can pick up, because clients understand a model faster than a plan.

We take commissions from housing cooperatives, municipalities and private owners, and we enter two competitions a year. We do not do interiors without the building, and we do not design what we would not want to maintain.

Before you write.

Yes, when they are used every day. The pavilion on the lake has three rooms. We do not take interiors without the building around them.

Always. Every stage ends with a finished piece of work that you own and can take elsewhere: a study, a brief, a model, a set of drawings.

A fixed fee, agreed before we start and based on four to eight weeks of work. You know the number before you sign anything.

Rarely. We want to reach every site in a morning and be home for dinner, because buildings are finished on site and not on screen.

Spring 2027. If your project cannot wait, write anyway and we will suggest two practices we trust.

Start with a paragraph, not a form.

Fill in the gaps. We read every brief on Monday morning and reply within five working days, also when the answer is that you should not build.
