A spatial practice for cultural institutions, hospitality, and private patrons. We build slowly, with materials that will weather, on plans that will outlast the brief.

A studio for slow architecture & long-lived spaces.

Meridian Arc is a 17-person studio working at the unfashionable intersection of permanence, craft, and quiet ambition — across Europe and the Mediterranean.

The studio was founded in 2008 around three principles we still keep on the wall in Zürich: build to outlast the brief, choose materials that age well, and treat every drawing as if it will be redrawn by someone who hates us in forty years.

Our clients tend to be cultural institutions, second-generation hoteliers, and a small number of patient private patrons. We do not chase competitions; we lose them. The work we want — adaptive reuse, civic buildings, the slower kind of hospitality — finds its way to us.

PRINCIPLE / 01

Permanence

Every project is designed to be photographed in fifty years, not five.

PRINCIPLE / 02

Material

Stone, plaster, oak, brass — chosen for how they’ll look once they fail.

PRINCIPLE / 03

Restraint

We remove three things from every plan before we sign it.

PRINCIPLE / 04

Place

The site brief gets longer than the client brief. Always.

Six disciplines, one drawing table.

/ 01

Cultural buildings

Museums, libraries, foundations, and the rare municipal commission that has time and budget to do it properly.

Lead time24–60 months
/ 02

Hospitality & restaurants

Boutique hotels, restaurants, and small resorts for owners who want the building to outlive the brand.

Lead time18–36 months
/ 03

Adaptive reuse

Industrial conversions, historic restorations, civic re-imaginings. The discipline we love most.

Lead time20–48 months
/ 04

Private residences

Three private commissions a year, ground-up or fully reworked, for clients who understand the timeline.

Lead time16–28 months
/ 05

Master planning

Districts, campuses, vineyards — where the building is the smallest part of the brief.

Lead time3–8 years
/ 06

Interiors & objects

Stand-alone interior commissions, exhibition design, and the occasional one-off piece of furniture.

Lead time6–14 months
Project № 048 · Under construction

Casa Alentejana

A 19th-century vineyard estate, returning to use as a 14-key inn after thirty years asleep. We are restoring the granite-and-lime fabric and adding two small new pavilions, set deep into the cork-oak treeline.
