The day after the race in 1927, the superstructure collapsed, caused by rot in combination with a heavy snowfall.
This caused the introduction of public control with scaffolding and bleachers in Norway.
By then, Holmenkollbakken was lagging behind internationally, and the world record at the time had exceeded 60 meters.
It was therefore decided that a new superstructure would be 19 meters (62 ft) tall and moved 9 meters (30 ft) further back.
Besserudtjernet was partially drained in 1928, but the hotels, which received their water from the lake, would not allow draining the following years.
In 1931, the lake was fully drained, which allowed the out-run to be longer.
In the 1930s, talk of an 80-meter hill started, which would potentially be built in Rødkleiva, further out in Nordmarka.
The Association for the Promotion of Skiing made a formal investigation into the matter in 1937.
There was agreement that the venue was becoming too small for international competitions.

Following the FIS Nordic World Ski Championships 1940 being awarded to Oslo, the Association for the Promotion of Skiing decided to build a larger in-run.
Construction started in 1938 and consisted of a 40-meter (130 ft) tall in-run tower.
The take-off was moved 12 meters (39 ft) further back and 6 meters (20 ft) higher.
The new structure was inaugurated in 1940, although the World Championships were canceled due to the Second World War.
The venue was subsequently left unused for five years during the German occupation of Norway.
German forces used the hill as a site for anti-aircraft artillery and the in-run was painted green.
In 1945, the venue received a new upgrade, this time with new grandstands and a larger profile.

In 1948, Oslo was awarded to host the 1952 Winter Olympics.
This caused a bonanza of plans, one superseding the other.
Until then, the grandstand on the sides of the hill had been temporary; prior to the Olympics these were rebuilt as permanent.
A new grandstand was built, a jury tower was constructed, as was facilities for the delegates, the royal family and radio broadcasting.
The in-run was rebuilt; while it previously had been a mess of open, wooden structures, it was shelled in, painted white and received an elevator.
The hill had to be expanded, and to allow this, the landing slope needed to be lifted by being built as an artificial structure.
Below the lifted part of the hill was built a three-story building, with the ski museum in the lower two floors and a restaurant in the top floor.
The lake was dug 6 meters (20 ft) deep and made a swimming pool during the summer.
The upgrades cost NOK 1.5 million, paid for by Oslo Municipality.
These upgrades resulted in an artificial lake being constructed in the off-run, which became a recreational and swimming venue for the city's residents.
The lake was at the time 3 meters (9.8 ft) deep and had a typical temperature of 10 °C (50 °F).
Oslo had a failed bid for the 1968 Winter Olympics.

Following Oslo's decision to bid for the FIS Nordic World Ski Championships 1966, it became evident that more upgrades would be needed to meet the International Ski Federation's requirements.
To allow for longer jumps, the take-off needed to be moved 10 meters (33 ft) back, and the lake dug deeper, with new concrete stands being built into the sides.
Combined with the tower being built taller, this gave a 56-meter (184 ft) height difference between the start and the off-run, allowing for the desired lengths.
The championships were the first to use computer to calculate the scores, but communication still used wired telephones, as had been used during the Olympics.
The public announcement and scoreboard systems remained manual.

By 1971, the Association for the Promotion of Skiing was no longer making much money off the Ski Festival, and they started discussing rebuilding the entire complex.
 Rolf Ramm Østgaard made a proposal which would include a twin hill, with both a normal and large hill.
Again the proposal of building the large hill at Rødkleiva was launched.
