architectural presentation and static protection of the remains of Haasberg Castle in Planina, Postojna

Haasberg Manor is one of the most important Baroque manors in Slovenia. It is located on the southwestern edge of Planinsko polje, on a terrace above the floodplain karst field formed by the Unica River. The owners of the Old Castle from the 13th century, the noble family Eggenberg, built a castle, the predecessor of today’s manor, at the foot of the hill in the 17th century. In 1716, their estate was inherited by the Italian noble family Cobenzl and transformed into the grandly designed Baroque manor Haasberg, which also included the exceptional natural environment in its architectural design. The manor is the work of the Baroque architect Carlo Martinuzzi (1673–1726), who worked in the early 18th century, mainly in the Carniola region, and to who we can also attribute the authorship of the Ursuline church and monastery in Ljubljana. When the Cobenzl family died in 1810, it was inherited by the Coronini family, in 1846, the castle passed into the ownership of the influential Austrian noble family Windischgrätz, who richly furnished it and hosted several prominent representatives of cultural and political life at the turn of the 19th and 20th centuries, such as Emperors Franz Joseph I and Charles I.


The castle was badly damaged in World War II, and its restoration in the following decades was slow and with great difficulty, which led to the preservation of only its outer walls and a small number of higher-quality building fragments. The earthquake that caused the collapse of part of the entrance facade on December 29, 2020, drew attention to the great danger to the remains and their increasingly rapid deterioration.


The project involves the partial reconstruction of the ruins of the castle with the aim of presenting them and preventing further deterioration. During the design process, several options for supporting the perimeter walls with internal or external secondary prefabricated structures were tested, but from the perspective of both the protection of the monument and its presentation, the most optimal option was to strengthen the perimeter facades by reconstructing the internal transverse walls, over which a new enfilade runs along the entire length of the castle. The enfilade is crossed by a walking and viewing ramp, with views to both, the remains of the castle and its exceptional landscape context. The ramp connects the fragments of the remains, which are arranged along the vertically varied Baroque axis – the main and highest quality architectural element of the castle.

The market building spatially represents the completion of the longitudinal subdivision of the gardens between Glavni trg and Meškova ulica – a transition from the small scale of service buildings between the gardens towards higher buildings leaning against the city walls. The design maintains an open view of the main city landmark – the bell tower of the Church of St. Elizabeth. A lively public space is created all day long with a wide variety of public events and catering options.


The market, consisting of two low pavilions and a flat roof floating above them, seeks the right balance between the division of the city parterre and the uniformity of the roof surface. The roof has a dual character – above as a green roof and below as a guide for views.

The flexible facade of the sales pavilions opens to all sides and allows for a variety of usage scenarios.
As a wooden passive building, the market serves to preserve natural and biological diversity and to present and promote urban self-sufficiency.

activation of the medieval city edge, a new park and upgrading of public spaces on a human scale

The urban revitalisation of Slovenj Gradec includes the activation of the medieval city edge, the upgrading of the system of public spaces on a human scale and the planting of a new peripheral city park. The key guidelines for designing a city for people according to Gehl have been taken into account: a city on a human scale, a city of active edges and a city pleasant for walking and cycling.


The new flooring of Glavni trg meaningfully intertwines longitudinal and transverse connections and defines the square as the main public space of the city. The human scale is achieved by dividing public spaces into micro-environments with different programs. The former thresholds are interpreted in the pavement, thus balancing the longitudinality of the square with its transverse geometry. Urban carpets are formed in front of the more important buildings, dividing the funnel-shaped square into a series of different nodes of activities, urban equipment and sculptures.

a place of remembrance at the transition between the verticals of the forest and the limitlessness of the horizon

The cemetery as a place of memory and a ritual place of farewell, both a place of community and a quiet place of contemplation, is designed at the transition between the verticals of the forest and the limitlessness of the horizon. The space of the cemetery is defined by contrasting relationships and transitions between open and closed, between light and dark, between here and hereafter.

It is located in an exceptional location, on a ridge above the central part of Ankaran, above the modernist church of St. Nikolaj along the Oljčna pot, which offers views of the Bay of Trieste and Slovenian Istria. It is precisely because of its exceptional location that the land was originally planned for commercial programs, but after protests by the local community it was re-purposed as a cemetery. Ankaran did not have a suitable place to say goodbye to the deceased, in therefore the new cemetery presents one of the main public spaces of the local community, both functionally and symbolically.

The forest cemetery shows its dual nature by design. On the one hand, it functions as a freely passable park forest intended for walks and contemplation, and on the other, as a series of marked burial fields, smaller cemeteries, which are lined up in terraces on the slope above the farewell building. The relief is geometrized into five terraces, which, due to their connection to the existing terrain, spread out like a fan. On the first terrace there is a farewell building, accessible by a low ramp. Walled burial fields are located on the next three terraces, and on the highest one there is a space for ash scattering. Smaller more intimate ambients are connected by a serpentine ritual path embedded in a network of forest paths connected to the center of Ankaran. The path is where the process of saying goodbye, mourning, remembering and reflecting, as well as socializing and meeting can occur. The well-thought-out dramaturgy of architectural and landscape elements lined up along the path directs the visitor’s gaze alternately along the terrain into the verticals of the forest and perpendicularly to the terrain towards the sea, into this unfathomable dimension that merges with the sky on the horizon.

The farewell building is close to the edge of the forest and set aside from the building mass of the church, which enables unobstructed views of the horizon. It consists of three parts. An entrance platform with a bench as an space of entrance open to the horizon, a farewell chapel as an introverted mourning space illuminated by zenithal light and a covered farewell area, separated from the chapel with a green atrium with focus into the depths of the forest via a water mirror. The longitudinal composition of the building relates to the structure of the cemetery walls and consists of long walls parallel to the terrain covered by a floating flat roof. Set to the back is an introverted volume with service facilities (storage, toilets, kitchenette). The location and transitory nature of the farewell building mark the beginning of the ritual path and the transition from the public to the space of memory.

The design of the burial fields derives from the interpretation of traditional walled cemeteries found near Ankaran, Lovran, Bertok and Stari Milje. The burial fields are surrounded by a low wall, which is interrupted by a higher urn wall at the entrance. Each burial field offers urn niches in the urn wall as well as an area for ground graves (both coffin and urn). The tombstones are set in place in such a way that they facing the entrance and have the view towards the horizon in the background. The last burial field is surrounded by a clipped hedge is intended for ash scattering and therefore consist of two levels. The upper level is bounded by a thin line of retaining wall, from which the undertaker scatters the ashes into seemingly infinity. In total, the cemetery contains 110 ground coffin graves, 246 ground urn graves, 180 urn niches and an area for ash scattering with 272 places for epitaphs.

All architectural elements materially derive from the colors and textures of the location. Amidst the massive washed concrete walls in the earthy color of the flysch layers, the polished concrete urn walls stand out, while the bright connecting path floats above the terrain. Individual accents and functional elements are made of local karst limestone, wood and metal.
Ankaran Cemetery, with its modern approach to the cemetery as part of a free-passable park forest accessible to all, transforms the traditional idea of ​​the cemetery space as a place of the dead into a metaphor for community.

diverse, open communications and quality of apartments, combined in a rational design

The location of the new residential neighborhood is at the intersection of the urban city feature and the landscape-diverse space between the fields and the Ljubljanica River. The correct placement of the new residential neighborhood in the space can enhance the urbanity of the area, which already has an extension in the existing local center with a public program along Litijska Street, and at the same time establish new connections that will enable greater integration of the area into the green system between Golovec and the Ljubljanica River.

The concept of the new residential neighborhood is based on five architectural and urban planning principles: the placement of 3 slender lamellas in the east-west direction, which define the future profile of Litijska street with a public program, delimit the bank on the northern edge of the location and form a transition between longitudinal and point-by-point roadside construction; the establishment of a central transitional green public space of the neighborhood in the east-west direction, intended exclusively for pedestrians and cyclists, which connects the neighborhood with the system of surrounding park and sports areas; the central public space of the neighborhood transitions into a semi-circular structure of porches with entrances to the apartments on the northern side of the lamellas, which define the duality of the buildings: on the southern side, the buildings are embedded in the urban city line and on the northern side in the structure of the green system; the slenderness of the lamellas enables a two-sided orientation of all apartments, with good two-sided lighting and ventilation and with open views to the south (Golovec) and north (Kamniške Alpe). The circular floor plan allows for flexibility, consistent separation of living and sleeping areas, and visually enlarges the modest living space.

the interweaving of three typologies in a tower of democracy

The spatial design of the courthouse comes from three typological units that are connected into a new whole: the court tower, the office slat and the park pavilion. An extended passage on the ground floor of the building covers the vestibule of the entrance hall from which the public rises to the level of the discussion halls. Their organization into the varied vertical volume of the court tower enables the development of the court palace’s vertical hall with multi-level interspaces and hall waiting rooms oriented towards the park and the city center with Ljubljana Castle. The court tower becomes the new representative public space of the city.

The extensive office program is arranged in a double-sided lamella that follows the building line along Dunajska cesta. The lamella floats above the public ground floor and descends into the ground-floor pavilion volume at the corner between Dunajska cesta and Topniška ulica. On the upper floors, the lamella rests against the court tower so that judges can access each floor of the tower directly from the internal corridor of the departments.

The court palace park is enclosed towards Topniška street by a ground-floor pavilion with a restaurant, which opens on both sides to the park and the street. The low volume balances the building mass of the palace and introduces a human dimension to the park area. The topography of the abandoned building pit and the unique ecosystem that developed within it are interpreted by the new, varied public landscape of the court park.

The duality of the public discussion and supporting internal administrative office program is demonstrated both in the volumetric design and the facade. The public part of the building is transparent and designed as a light structure with slender columns, thin metal railings and building elements in the interior. The office lamella is designed according to the principle of a glass facade with movable aluminum blinds, which create the impression of light awnings. Movable blinds allow variation of the uniform facade area and the impression of individuality within the repetitive rhythm of offices.

reversible interventions in the archaeological area with a view to the future

The new intervention is designed to transform the degraded and inaccessible landscape of the existing quarries into a place of contemplation with the microclimate of a Mediterranean garden and a place for recreation and summer events.

The interpretation center is a floating atrium pavilion, which with its materiality and design is subordinate to the context in which it is located, blends with the landscape and serves as a medium of education about the cultural and historical heritage of the location and presentation of the production processes of ceramics. With its appearance, it represents an airy, light, elemental architecture and a completely reversible intervention in the space.

a natural thermal complex among the trees

Terme Jenina is located on the southern slope of Dobrova, above the Jenina valley. The topographically varied forested ridge is located between the Mislinja and Jenina valleys and extends north towards Slovenj Gradec. Its location is in a historically important transitional area between the Šaleška Valley and Koroška. Due to the thermal water deposits, the location is interesting for tourist development, but at the same time it represents an oasis of unspoiled natural environment, which needs to be preserved and carefully intervened in.


The concept of urban development of the area follows the existing landscape and settlement patterns. It consists of three program zones that follow each other along the bank from south to north and define a clear spatial hierarchy: a zone of wet meadows along the Jenina with a system of new accessible footpaths and an entry point to the nature reserve, a zone of park forest with a new circular walking path and an educational and adventure trail along the Jenina, and a zone of a new clustered forest settlement, which is adapted to the varied terrain with its building and settlement typology. The clustered forest breaks up the existing closed forest stand into transitional interspaces and clearings. At its edge, the longitudinal structure of the hotel is laid on the terrain as a long floating roof that surrounds the internal atrium. In the hinterland of the hotel, there is a clustered building of individual houses, which are placed between forest tree clusters and follow the edge of the steep bank.

women’s prison as open architecture at the intersection of nature and heritage

What should be the place for the enforcement of sanctions, which will encourage humanity and the reintegration of protected women into society? The reflection on the modern prison is based on the promotion of social inclusion instead of isolation and thus preparation for freedom. Here, architecture can play a key role only to the extent that it ensures, within the required security requirements, the openness of the design, which enables and encourages communication with the outside space. The concept is developed from three elements: a plinth, which redefines the forecourt of the castle and highlights the castle as a spatial dominant; walls that rise from the plinth and terrace the area into which the new program slats of the shutter are placed; notches at the contact with the existing topography, which illuminate the basement floors, open up views of nature and establish the necessary height of the protective perimeter.

a transparent palace on the historical axis

The new building of the State Audit Institution of Montenegro is a compact building volume that follows the building lines and at the same time is morphologically connected to the geometry of the surrounding buildings with the notch of the intermediate vertical hall. The hybrid typology of the business palace combines a low pavilion part on the ground floor, open directly to atriums with a mediterranean garden, and a vertical urban hall that runs through all floors. This works as a generator of communication between employees, as all workplaces are visually connected to each other. The flexibility of the work space is achieved with a variable configuration of workplaces, which is provided by an open floor plan without structural supports – the entire building is supported by two reinforced concrete cores on which the steel structure of the floor rests.
