EXPERIENCING a Remarkable Renaissance 
MONUMENT SAVED AND TRANSFORMED BY AUBÖCK
Until recently, the Baroque chateau in Boršov nad Vltavou was on the list of monuments in danger. This picturesque three-winged building with a charming mansard roof, originally a fortress from the time of Charles IV, fell to the Budějovice monastery after the Thirty Years' War and the clergy rebuilt it in Baroque style. Now it shines again in all its glory. This is thanks to the new owner, the construction company Auböck, which bought the building and completely reconstructed it after years of decay and futile dreams of reconstruction.
"It's a matter of the heart, and so the idea came to mind: let's save this monument while it's still on the brink of being able to do so. If it continues to operate like this for another two years, it will be in an unsalvageable state. Our aim is to treat the project as a monument, but it has to have some economics," says Auböck managing director Ing. Jan Vilánek.
13 Flats and Community Center Unveiled at Chateau
Heritage building transformation

13 flats have been built in the chateau and the former malt house is home to the community centre of the non-profit organisation Josefína. Auböck has extensive experience in the reconstruction of monuments. It accounts for a third of their contracts. They reconstructed the Budweis Hotel in České Budějovice, restored the facades of the church in Dobrá Voda near Nové Hrady and participated in the reconstruction of the Saltworks on Piaristický náměstí in České Budějovice. 

The reconstruction of heritage buildings is not a routine construction matter. It requires the use of special technologies, suitable for connecting with the often disturbed original masonry and coordinating the work with conservationists.

Auböck relied on the "Monuments Programme" system solution from the manufacturer LB Cemix for the reconstruction. This is a special plaster system that includes individual plaster layers from spraying through the core plaster to the top plaster. The plasters contain only lime and pozzolanic binders as well as other additives to improve their properties. The pozzolanic binder reacts with the lime components and water, hardening the plaster and replacing the commonly used cement. The application of Lime Conservation Spray 144 was carried out at Boršov Castle. Its application improves the adhesion of the subsequent Lime 102 core plaster. Furthermore, Lime Conservation Stucco 134 with a grain size of 0.7 mm and its coarse variant with a grain size of 1.2 mm were applied.

Innovative plaster system transforms dilapidated castle into charming jewel

Due to the condition of the dilapidated building, special remedial plaster systems for saline and damp masonry structures, which Cemix manufactures for historic buildings and listed buildings, had to be applied to the interior. The principle of the system's function is based on a special distribution of pores that are connected by a fine capillary system. This combination significantly multiplies the surface area of the evaporation zone and thus evaporates moisture from the masonry at an enormous rate, although the plaster remains dry and free of salt efflorescence. The quality of these products is guaranteed by many years of knowledge and numerous Czech and foreign references.
 

The complete reconstruction, including the implementation of internal plaster and external facades, has made the ruined chateau an incredibly charming and picturesque place with a "South Bohemian" Baroque character. The building retains an atmosphere of intimacy and comfort that is in harmony with its use.
