About Forma
We are a studio of twelve — architects, interior designers, and technical specialists — working on residential, cultural, and commercial projects across Norway and Scandinavia. Our scale is deliberate. We take on fewer projects than we could, because the attention each one receives is part of what we promise.
Our work ranges from private villas and urban apartments to cultural institutions and office headquarters. What connects them is an insistence on materials that age well, spaces that serve their inhabitants, and details that reward close inspection.
The Team
Erik Halvorsen
Principal Architect, Founder
Erik founded Forma after a decade at Snøhetta and Reiulf Ramstad. His work is defined by a commitment to materials and light — and an aversion to anything decorative that doesn't also serve a structural or spatial purpose.
Marte Lie
Senior Architect
Marte leads our residential practice. She has a particular interest in the relationship between a building and its landscape — how a house settles into its site, and how that changes over the seasons and over time.
Jonas Berg
Head of Interior Design
Jonas oversees all interior design work at Forma. He trained in Stockholm and brings a rigorous approach to material specification — every finish, every fitting, every piece of furniture is chosen against the whole.
Recognition
"A house that refuses decoration in favour of depth. Every surface has been considered; nothing is there by accident. This is architecture that trusts its inhabitants to notice what matters."
Project
Private Villa, Oslofjord
Jury
Awarded unanimously across all jury categories
"Forma has produced a home that feels inevitable — as if nothing could have been placed differently. The relationship between structure and landscape is handled with rare restraint and confidence."
Project
Forest House, Nordmarka
Category
Residential — over 350m²
"The interiors work because they have been designed from the inside out. Forma understands that a room is not a background — it is a condition. The material palette here creates a quiet atmosphere that deepens with time."
Project
Penthouse Apartment, Aker Brygge, Oslo
Notable
First Norwegian studio to win in 11 years
"A public building that succeeds in being genuinely civic. It does not perform openness — it achieves it. The reading room alone is worth the visit: light arrives exactly where it is needed, and nowhere else."
Project
Nesodden Public Library
Shortlisted
Nordic Built Award, same year
"Forma has built a body of work in eight years that most studios never achieve. What distinguishes them is consistency — not of style, but of seriousness. Every project asks what a building owes the people who will use it."
