The rebuilding of the brewery city block was the last subject of the so called Aura Brewery. They called the architect Alwin Jacob from Stockholm to design the building, which was finished in 1885. It was converted and extended several times afterwards. The building was used as a brewery until the 1980´s and was converted to the headquarters of the contracting company Hartela Ltd in 2001. About one hundred employees are working here. 

The two basic ideas of the redevelopment design were to change the main entry to the Aura River bank side and to open an entry hall through all the three floors to attain a free height of 17 meters. The opening of the hall made it possible to extend daylight into the internal spaces of the vast building mass.

The open work places are situated along the external walls. The more closed rooms are in the middle of the mass separated from the open view by movable glass partitions. The transparency of the conference room is electrically adjustable. A part of the service spaces and storages as well as the social rooms of the employees is located in this more closed part, too. 

The glass wall of the core space forms a second facade into the open hall. Constructing this extensive glass walk was a challenge because of the continuous movement of the riverbank glacial clay, even though the foundations were strengthened for the reconstruction. The possible vertical moving of the structure was to be taken into account even in the design of the internal spaces. Specific height control devices were designed under the glass wall to avoid disturbing deformation.

The mechanical and electrical services are led into the two main floor constructions, where they are installed upon the old vaults. The ventilation and sprinkler systems are thus out of sights.

The representative sauna and the training department are located in the bottom floor.
