The design emphasizes activating the square as the city's urban center, creating a vibrant, year-round meeting point for residents. Centrally located, the hall mediates between public space and the city hall, featuring a small café and multifunctional space for workshops, concerts, readings, and markets.
The hall's permeable structure blends interior and exterior spaces, providing scale and context. Exterior spaces around the city hall connect with the surrounding streets and squares. The library, located in the dual-gabled attic, offers a contemplative retreat.
The city hall frames urban activity, with offices, a bank, and tenant spaces accessed from the south via the forecourt, serving as an address and meeting point. The building's contemporary architecture emphasizes transparency and sustainability, with large wooden windows and cathedral glass balustrades. The hybrid timber-concrete construction allows for large spans and a flexible, prefabricated skeletal structure. Its compact design minimizes the footprint and offers short internal paths and diverse views.

Located on a former airfield northwest of Karlsruhe, "Greenville" is an ecologically oriented urban extension. By introducing an independent, rectangular order, the urban plan discontinues the star-shaped pattern of the historic center, emphasizing the surrounding nature reserve.
At the intersection of urban demarcation lines, the district square offers residents a main contact point for everyday life and social interactions. It also serves as the neighborhood's sound chamber, resonating community, social life, and urban identity.
The proposed building, the northern spatial boundary, features lively, delicate architecture. The orthogonal figure illustrated in the development plan is superimposed with circular shapes, dividing the building into two segments.
These “unequal twins” vary in typological order, proportion, and height. In the west, access to apartments is via staircases with a communal entrance hall. In the east, access is through an access gallery. Despite their sparse design, the apartments offer architectural generosity through diagonal spatial references, layering, and open floor plans.

Through our design, we aim to establish the concept of an inner embedded garden as the guiding landscape idea for the new Leutschenbach quarter. By minimizing the building‘s footprint, we can create a generous open space that introduces a sense of distance between the new apartments – designated for elderly housing – and the heterogenous neighborhood, which is dominated by office-spaces.
The undulating façades contrast with the orthogonal lines of the surrounding area, embracing the quasi-natural aesthetics of the open landscape. A dynamic interplay between surfaces, volume, and vegetation anchors the design‘s almost ephemeral form, enabling a harmonious connection with the built environment. The vegetation shapes and defines thresholds, facilitating a seamless transition between public and private domains.
Much like a sculpture, the robust structure offers diverse perspectives and interpretations in terms of its spatial and volumetric arrangement. Delicately branching pathways of varying hierarchy weave a network of connections, linking the internal spaces to the surrounding neighborhood. Access to the building is conceived from the east, accommodating both residents and visitors. Courtyards interact with the two-story entrance halls, establishing a distinct focal point for the building while functioning as a communal gathering spot for the residents. The two-story communal areas, fitness room, and laundry facilities are interconnected by an inner promenade, inviting visitors to linger with its diagonally arranged rooms functioning as an extended access zone.
The majority of the apartments enjoy dual-sided orientations, providing diverse views and a poetic interaction with the changing seasons. This interaction is further heightened by the undulating façade, resulting in a myriad of visual perspectives. Equally crucial is the ambivalent nature of the loggia space: its geometry defines it as a private outdoor seating area, yet the loggias form a spatial continuum, encouraging neighborly proximity.
The diversity of typologies enables us to cater to the varied needs of the residents. In the more outwardly oriented apartment types, kitchens or living rooms face the communal loggia, allowing them to benefit from the evening sun in the west. Conversely, conventionally accessed apartments are aligned with the staircases, offering a more secluded living experience with the option to use the common areas as desired.

The site in Moosach is located within a suburban area and lies adjacent to various building typologies. To the southeast, the urban structure is characterized by single houses, while the north is dominated by apartment blocks.
Over the years, a void has emerged in this specific location as dense vegetation, mainly consisting of fruit trees and conifers, has taken over the space. Our design approach originates from the intention to preserve the site's green character while simultaneously proposing a development concept that corresponds to the appropriate density.
This intention has led to the development of a design that involves a radial arrangement of apartments, accessible through centrally illuminated staircases. The high compactness facilitates expansive, uninterrupted outdoor spaces and makes the building responds respectfully to the smaller scale of the villas to the west.
The new ensemble is defined by two separate structures that share a resemblance in both structure and façade. This coherence enhances the perception of the development as a harmonious entity while simultaneously establishing an independent identity and a recognizable presence to the outside.
The fundamental structure of the houses is clearly and almost schematically defined. The organic façade design opens the residences to the surrounding green space, enabling optimal lighting and orientation for each apartment.

Meidling, Vienna's 12th district, sits at the city's geographic center, nestled between Fasangarten in the west and Margaretengürtel in the east. Over the past century, this district has evolved into an area with a distinctive character, despite its initial generic layout of block structures. The interplay of gentle curves, spontaneous setbacks, and unexpected breakthroughs blurs the boundaries between public and private spaces, resulting in a unique hybrid urban landscape. This diverse environment ranges from closed and perforated building blocks to meandering rows and free-standing structures.
Meidling's urban fabric is notable for its varied scales. On one hand, the district features an array of individual units that differ greatly in height and architectural style, creating a heterogeneous appearance. On the other hand, it is home to large-scale "Red Vienna" estates, which embody social-reformist ideals through coherently designed developments. Notable examples include the Liebknechthöfe and the Volkswohnhaus by Jacques Schwefel, where intricate layouts emphasize communal plazas and access spaces.
The design for the Ruckergasse elementary school's extension addresses the district's urban character on an architectural scale. The site, framed by five significant structures reflecting 19th-century bourgeois styles, presented an opportunity to harmonize the existing elements. The new building, positioned at the property line, continues the block's alignment while subtly reinterpreting classical elements. The project, focused on adding classrooms, wardrobes, and a student restaurant, emphasizes spatial composition and architectural identity, with patios breaking up the school's mass and disguising spatial orientation.
