On the other hand, running water was installed already in 1905, which meant that the hall had aquariums with live fish for sale, such as pikes, eels, breams and flounders.

In 1957 the first refrigerated counters finally arrived to the hall and the first florist and stationery opened shop there.

The adjacent building was supposed to share a side wall with the KOP-kolmio, thus the facade facing the market hall is relatively plain.

The renovation works were extensive, and e.g. the old marble counters had to go, replaced with stainless steel, however, the facade was left unchanged.

The renovation also meant that the number of shops was cut down by half as the lots had been enlarged and some of them had been replaced with cold storage.
