Meridian

Architecture and interiors. Lisbon and Kyoto.
Tagus Library, 2025 — shown above.

Practice

Meridian is an architecture practice of 34 people working on housing, cultural buildings and public space. We start from the site and the budget, and design buildings that are simple to build and cheap to run.

Casa do Vale, ground floor

A single-storey courtyard house near Sintra for a family of four. The children and the parents each have their own wing; the kitchen and living room sit between them and open fully onto a planted courtyard.

Services

Architecture

New buildings from feasibility to handover: housing, cultural, civic and workplace.

Interiors

Fit-out, furniture and lighting, designed with the building rather than after it.

Masterplanning

Urban frameworks and public space for cities, cooperatives and landowners.

Retrofit

Reuse and energy upgrades of existing buildings. A third of our current work.

"They designed a market hall we can actually afford to run. Three years in, it costs less to heat and light than the old car park did."

We are architects, interior designers and engineers in two offices. Each project is led by a partner from first sketch to handover, and we keep the teams small so the people who draw the building also visit the site.
