A new station building was opened in 2020, featuring a large wooden triangular roof with windows allowing light down to the indoor spaces and platforms,[1] replacing the previous building from 1988.

The upgraded station will accommodate an underground bicycle storage area, and cycle shop replacing the current outside stalls for rail users.

The contract to re-design Assen station was won by the Powerhouse Company and De Zwarte Hond.

FlorijnAs is overseeing the wider works of improvement in the city and their website, available in Dutch and English, explains that: "Towards the end of 2015 the relocation of the cables and pipes for the station begins.

However 27 August 2015 saw the website spoorPRO release an article, stating that the works on the tracks have been pushed back till 2017, due to "hard work being scheduled elsewhere on other projects in 2016", while further in the article ProRail and contractors are stated to have said they are "currently working on the biggest track renewal since the birth of the railways".
