Soft Modernism: Bryn and Ellefsen's Physics Building at Blindern
Essay
They won the competition with a Roman temple, went to look at what Europe was building, and came home to strip their own drawing bare. What stands at Blindern is functionalism that kept the brass, the colour and the curve.

The story modernism tells about itself is a story of conversion: the young architect sees the new work, throws out the mouldings and never looks back. Fysikkbygningen at Blindern is that story with the receipts attached, because both halves of it survive on paper. Finn Bryn and Johan Ellefsen won the University of Oslo competition in 1926 with a Roman temple: a columned facade in the centre, a round vestibule ringed by galleries, a dome on top, all of it in red brick and granite. Then they went to Germany, France and the Netherlands to see what was being built, came back and took their own drawing apart.
What they kept was the symmetry and the materials. What went was everything that made the building an argument about Rome. The tall windows dropped, the dome and the temple front disappeared, and the facade was regrouped into the harder geometry that stands there now. The building was finished in 1935 and opened in 1936, ten years after they won it, which means the design that made their reputation was quietly demolished by its own authors somewhere between the competition and the scaffolding.
It helps to remember what Blindern was at the time. Not a campus: a farm. The university had bought agricultural land north-west of the city and was moving out of its neoclassical quarter downtown, and the first buildings stood in a meadow with a dirt track running past them. There was no context to answer to, only a field, a brief and a decade that believed a building should be honest about its purpose.
Even stripped, the building reads as civic architecture rather than as a laboratory. A central tower rises out of a long horizontal block, its top floor cut open by a continuous band of glazing, and the brick is laid dark and warm rather than rendered white. Norwegian functionalism arrived through Sweden and Denmark rather than direct from Dessau, and it arrived softened: less manifesto, more craft, willing to keep the material a country already knew how to build with. Bryn and Ellefsen had been in partnership since 1922 and would go on to design the Norwegian pavilion for the 1939 World's Fair in New York.
The plan is disciplined where discipline pays. A physics faculty in the 1930s needed vibration-free floors, long service runs, blackout rooms and a lecture hall that could seat a generation of students, and the building solves all of it with the efficiency the period demanded. It housed chemistry too, until that institute moved out in the 1960s and the name shortened to the one it carries now. Then, at the point where circulation happens, where people actually meet the building, the geometry loosens. Stairs sweep rather than turn. Handrails are brass. Ceilings lift. Colour appears where a purist would have left plaster.
The vestibule is the whole argument in miniature, and it is the one room where the demolished 1926 scheme still shows through. Bryn and Ellefsen had promised a domed rotunda; what they built instead is a double-height hall with a black and white zigzag floor, closer to a 1930s ocean liner than to a laboratory, opening on both sides so that the space worked as a public passage between Majorstuen and the campus rather than as a lobby.
Through the middle of it hangs a Foucault pendulum: a gilded ball bearing twenty centimetres across and weighing thirty-two kilograms, on a wire of 14.1 metres. Foucault's original in Paris in 1851 was a 28-kilogram weight on 67 metres of wire, the first demonstration in a room rather than a sky that the earth turns. At Oslo's latitude of sixty degrees north the plane of the swing takes 27 hours and 43 minutes to come back round. It is a working instrument and a piece of interior design at once, the one object here that explains the discipline housed in the building without a single word.
Above it, across three walls around the main entrance, Per Lasson Krohg painted 260 square metres of fresco with glass inlays and painted glass. He won that competition in 1935, the year the building was finished, and the work was completed in the autumn of 1938, paid for by the consul general Peter Krag. It is called Atomet i verdensrommet, the atom in space: the sun and the planets ringed by galaxies drawn as a woman and a man, with the aurora running through the composition. Krohg would later paint the mural in the United Nations Security Council chamber in New York.
Note what that means for the chronology. The classical scheme was abandoned in the late twenties as too decorative for the new century, and then, with the functionalist building standing finished, the university ran a competition to cover its entrance in painted cosmology and hung a brass weight in the middle of it. The glazing bars of the stair window cut straight through the picture. The grid and the painting hold each other rather than compete, and the conservators from NIKU who cleaned the work in 2015 were maintaining something no purist reading of the 1930s can quite account for.
That is the reason the building still teaches something. The heroic version of the decade asks a structure to be honest, and honesty gets understood as bareness. Fysikkbygningen accepts every functional demand of its brief, drops its own columns to do so, and then treats warmth, colour and curvature as functional demands too, on the grounds that the people inside are also part of the programme. Nearly a century on, with the creeper turning scarlet over the entrance each October and the pendulum still swinging, it looks less like a compromise with modernism than a correction to it.
