Other Information

The house was built after the 1st world war as notary's villa in the former periphery of Tolmin where richer buildings were located. The house expresses the characteristics of secession and is listed in the Register of Slovene cultural heritage. Firstly served as a single family house, after the 2nd world war it was used for State security administration. Later it was rearranged to a four apartment building. The earthquakes in 1998 and in 2004 caused severe damage on the building. It was therefore included in the national programme of renovation after the earthquake.

The building size is 15,35 x 12,70 m and constitutes of the basement, ground and first floor and the attic. The construction is made of bricks, the ceilings are wooden. The roof has four sloping sides with the elevation of 30°. The house was built in the town walking area in secession style. The facade was still in its original state. Originally this was a single family house with elements that showed the wealth of the owner. The investor wanted to insulate the walls from the outside but the facade itself was one of the main protected elements of the building (in addition to the size, roof inclination, colour of the facade, windows, etc.). In the end it was allowed to do it because the facade elements were so damaged that they rather made a replica of all elements and integrated them on the new facade. All the other elements of protection were respected. In the renovation 2 additional apartments were established, in total there are now 6 apartments.
Städtebaulicher Kontext
The building is part of a small town Tolmin, close to the park and town centre. Due to the size there is no public transport, but all services are within walking distance.


The bulding is listed in the national cultural heritage register. The heritage office highlighted the importance to keep the dimensions of the construction and the roof while maintaining the facade with ornaments. The investor had to respect the window openings and frames as well as the doors. The demand was also to keep the balconies with iron fences and a stone staircase at the entrance.
Denkmalwert und wie er bestimmt wurde
The house was built after the 1st world war as notary's villa in the former periphery of Tolmin where richer buildings were located by the park of the town. It is the only one that preserved completed external image (characteristics of secession) and is listed in the Register of slovene cultural heritage. The protection of the cultural heritage is to preserve the design, materials, production, placement in the environment and area of influence. The first idea was to allow only inner insulation of the walls but after discussing possibilities the autohorities allowed also insulation from the outside. This meant removal of ornaments from the facade and replacement with full replicas after the insulation layer. This compromise was necessary to optimise the inner space in the best possible way.


Erhaltungszustand der Gebäudehülle
The outside of the building was still in its original state. This was the only villa from the time after the first world war that hasn't been changed up to now. The only reconstruction was done inside to adjust it for the needs of appartments.

Ziel der Sanierung

The building was used for apartments already before the earthquakes. Due to the damage it was evaluated and there was a decision for a full refurbishment including statical improvement and energy efficiency. With the renovation the building gained additional rooms.
Gab es eine Änderung der Nutzung?
The house was first used for services, the municipality decided to use it for social housing after the renovation.
Was the intervention planned following a step-by-step approach?
The building was part of the earthquake refurbishment process that followed the necessary steps, later it was upgraded also with municipal needs. The basic funding was dedicated to statical improvement of the construction, everything else had to be financed by the investor.
Gewonnen Erkenntnisse / besondere Erfahrungen
Cultural heritage first only allowed refurbishment of the original facade with ornaments and pointed out internal insulation as the only possible way. After a detailed analysis of the walls, ornaments and other important elements, they acknowledged that it is in a very bad condition and refurbishment would not be possible. In addition they decided to allow minimum outer insulation with full replica of the original facade including ornaments.

Finanzielle Aspekte

The building was damaged in the eartquake and included in the national programme of refurbishment that was managed by the technical office. The planned intervention was based on statical improvement of the construction. The owner Municipality of Tolmin later decided to also insulate the building, improve living conditions and invest in a new heating system. The overall budget is therefore a combination of national and local public funding.
