When Østfold Line opened in 1879 it followed a more westerly right-of-way through Holm.
The line passed over Ljadalen on the Ljan Viaduct.
The ground conditions were poor through Holm and the Norwegian State Railways therefore decided to build a new rote via Hauketo.
The new route resulted in the opening of a station.
Locals proposed that the station take the name Holm, which the area was known as at the time.
NSB rejected this, stating that there was already a Holm Station on the Vestfold Line.
They proposed instead that the name Lia could be used, after the former croft at the site.
In the end they settled for both—Holmlia.
The line past the station received double track on 15 December 1936, followed by electrification on 18 January 1937.

Development of the Holmlia area started in 1970, following the construction of a cluster of single dwellings in the 1960s.
By the 1980s the population had reached such a level that the simple station from 1932 could no longer handle the ridership.
A new station was therefore built, 200 meters (660 ft) north of the former.
The station was placed under an overpass, allowing for easier access and better transfer to buses.
The station opened on 2 June 1982.

NSB started large-scale unmanning of its stations from the 1970s, following the introduction of centralized traffic control.
This led to a paradigm shift in the way new station were designed.
There was no longer a need for a station building.
Instead focus was on larger platforms to handle many travelers, better access and large roofed areas where passengers could wait.
Holmlia was the first major project of this kind in Norway and represented a trend where suburbs with high ridership received stations with high throughput.
Arne Henriksen at NSB Arkitektkontor was selected as the head architect, and Holmlia became his breakthrough.
He would continue to dominate railway architecture in Norway the next two decades.
Holmlia Station won him the Houen Foundation Award in 1988.

By the 2010s the amount of traffic at Holmlia was so high that access to the platforms had become a bottleneck during rushhour.
Holmlia had become one of the busiest commuter stations in the country.
The Norwegian National Rail Administration therefore decided to also build an access structure to the northern side of the platforms.
Another concern was to spread out passengers more throughout the platform to speed boarding times.
The platform height was raised from 70 to 76 centimeters (28 to 30 in) to allow for step-free access to trains.
The art stone which was previously located at the northern end was moved to the south, where the disused kiosk was moved.
Meanwhile, Oslo Municipality expanded the overpass over the station, to give room for more space for buses.
The new section was designed by Linje Arkitekter.
The new facilities opened on 7 May 2012.
The southern platform structures were renovated in 2016.
As the superstructure is listed, the work largely consisted of retouching the existing design, as well as adding an elevator.
