The second floor, which originally was an unheated attic, has been designed with acoustics suitable for the performance of live music. The only exterior addition to the building is a tower containing a lift. Indoors the details of the original home have been preserved as far as possible. Two parquet floors and a few wooden floors remain. The ceiling structures have been left visible in the attic.
All tile stoves are original, as is one plate mantled stove.
The house hides advanced technology for heating, lighting, ventilatand humidity regulation. Everything has been installed as invisibly as possible, so as not to intrude on the intimate atmosphere of the old building. In earlier years the town prison was located in the back-yard house. The old cells have been converted into small storerooms and other facilities and we have preserved some of the graffiti and thoughts written on the walls by the prisoners. In one end of the building, facing the Tarvonsaari park, lies the Pihatalon Studio - exhibition facilities on the two floors.
