In 1911 the city council gave the monetary action chamber the task of designing complete sketches for the new market hall with cost and worth calculations.
As experience had shown that trade in specialised market halls suffered, a diverse selection of products for sale was seen as better.
On 14 November 1911 the city council made a decision to build the two-floor market hall.
[5] In 1912 the support beams, foundation and stone layout of the market hall building were made.
After a workers' strike had stopped the construction autumn had already progressed so far that masonry work could not be started.
The market hall, which was hailed as the largest and most modern in all of Europe, was opened on 1 June 1914.
"[6] Shortly after the opening it was decided to equip every store at the market hall with electric lights up to 25 candlepower.
For the 1952 Summer Olympics in Helsinki, the market hall was fitted with a modern toilet.
Many merchants were unemployed during the reparations and could only be re-employed when the market hall was opened on 1 December 1971.
During the reparation, the air condition of the building was renovated and a set of escalators were installed between the two floors.
