Hansen og Holm Arkitekter AS is an Oslo-based architecture firm helping homeowners and property owners get their building projects approved and built. The team specializes in building permit applications (byggesøknad) and the technical drawings that go with them — everything from small additions and garages to loft conversions, basement renovations, and change-of-use projects. What sets the team apart is their background: several of them previously worked as municipal building case officers, so they know exactly what local authorities look for in an application. That shows in how they work: clear communication, complete submissions, and a process built to avoid the back-and-forth that usually slows permit approvals down. The firm operates from three offices in Oslo, Bergen, and Fredrikstad and takes on projects across all of Norway's municipalities. Most clients are private homeowners working on extensions, conversions, or subdivisions, though the team also supports larger residential projects. Every new inquiry starts with a free, no-obligation evaluation along with a written quote for the drawings and/or permit application.
