How 3LHD breathed new life into the old Janković castle in Suhopolje

The dilapidated building from the 18th century underwent a major renovation during which the original elements of the building were retained with the addition of modern architectural details.

Janković Castle in Suhopolje near Virovitica is a cultural attraction and a protected immovable cultural asset of architectural heritage, while the park around it is a naturally protected asset of park architecture. The castle itself was built in the middle of the 18th century, and it got its current look at the beginning of the 20th century.

He bought the manor in Suhopolje at the end of the 18th century from the imperial chamber Count Ivan Nepomuk Jankovic. During its rich history, the castle, in addition to the owner, also changed its purpose. After the First World War, Russian refugees were housed there, and from 1943 to 1960 it was turned into an orphanage. From 1964 to 1973, the castle served as a kindergarten and elementary school.

So, after a long time, the time came for the Janković castle to finally open restore the old glow with the help of EU funds. That job went to the Zagreb bureau 3LHD who signs an architectural project to renovate the castle.

Over time, the building was brought to a state of disintegration, so in the end we completely replaced both wings with new ones.

The starting point for making this project was the need for rescue culturally, historically and architecturally valuable Janković Castle in Suhopolje since its further decline.

The castle complex was in extremely poor condition. As some parts of the house are from the 18th century – the age of the building and the damage caused over time were certainly the biggest challenge. The most demanding were the parts that collapsed and that needed to be returned to their original condition.

“Over time, the building was brought to decay states, so that in the end we completely replaced both wings with new ones and kept only their primary volume, and we reacted modernly to all architectural elements. Beautiful arched construction of brick in the basement of the main building it is completely preserved and we insisted on that because it is perhaps the most valuable part of the castle in terms of construction. ” – say the architects from 3LHD.

New design

The main building of the castle is owned baroque landmarks: irregular base, indented roof and north façade as the main façade. It originally had a compact and regular rectangular base. All buildings have changed their shape over time due to upgrades, so there have been significant changes in the structure of the building.

The new design fully respects the historical architectural and stylistic features of the castle. The internal structure, spaciousness, volume and historical organization of the main building of the castle have been completely preserved.

All destroyed parts they are replaced by replicas, identical material structures. Parts of walls or vaults with a destroyed brick structure are rebuilt with bricks of the original format with the use of special mortar for old buildings under protection. The wooden roof structure has been replaced with a new one, in accordance with the new geometry of the space.

Since there were preserved examples, all carpentry, windows and doors were made using the replica method.

The main building has been completely renovated by the remediation method of the original elements in places where it was possible. New mortar it was done in places where the damage was such that it was impossible to keep the historical substance. The mortar is harmonized with the historical one in granulation, texture and color, and according to the proposal of the conservation guidelines and the agreement with the competent conservation service.

Since there were preserved examples, all the carpentry, windows and doors were made by the replica method. The roof panel is made cement-fiber boards in natural gray, as the original most similar, but also the highest quality cover material.

The facades of both wings have been modernly reinterpreted, with materials, color, texture and shape harmonized with the character of the space. According to the findings, both wings were ivory in color.

The original identity of the building

“In the case of reconstruction projects, the real situation can be seen only when the construction and all the elements (floor, wall, ceiling) are opened. In this case, some parts were really in complete disrepair and that is why it was decided to move to a new construction, and literally the decisions were changed on the spot in cooperation with the conservators, and the most common decision was a replacement building. ” – say the authors of the renovation of the Janković castle.

It has been a big problem over the years accumulated moisture in the walls, which has been drying out for months. Traditional materials were used in the renovation and reconstruction because the desire was to preserve the original identity of the building.

Castle as a center for visitors

With the reconstruction, the castle was converted into visitor center. Facilities for guests include a multimedia space (5D cinema), a souvenir shop as accommodation and catering facilities. In the west wing there are catering facilities: restaurant, kitchen with accompanying facilities and storage. In the east wing there are accommodation units and wellness facilities. The modern exhibition space unites natural, cultural, artistic, material and intangible sights and the heritage of Virovitica-Podravina County.
