Czech architecture studio Architekti DRNH was commissioned to design the residential building "Diorit," situated on the site of a former diorite quarry, on abandoned plots located on the border of the Komín and Bystrc districts in Brno, Czech Republic, within the narrow valley of the Svratka River.

The site had been abandoned for a long time, which allowed it to transform from an industrial extraction environment into a dynamic ecosystem, where nature enabled the presence of rare species that could not find suitable conditions in the nearby surroundings. This was a situation the architects identified from the outset, proposing a design that engages with the site's rich biodiversity.

Architekti DRNH adapted the project to the conditions of the site, making the section function as a noise barrier with the street and integrating it smoothly with the courtyard, which follows the morphology of the original rock walls of the quarry, with steep slopes and terraces. The building’s image blends with the natural tones of the landscape: soft plaster hues, glass facades with milky profiles, gentle curves, and sharp interruptions, complemented by extensive vegetation.

The project includes apartments ranging from studios with open kitchens to four-room apartments with open kitchens, most oriented toward the communal park through green terraces. The spacious apartments at the ends of each floor also feature large rooftop terraces overlooking the Svratka Valley.

The load-bearing structure consists of transverse and peripheral reinforced concrete walls and sand-lime brick, with monolithic slabs. The underground garage preserves exposed rock walls thanks to its monolithic structure. Circulation combines stairways, corridors, and a glazed corridor facing the road, which also acts as a sound barrier.

The building, classified as Class A, is heated and cooled by heat pumps that draw energy from deep wells. Rainwater is stored in tanks for irrigation, and the excess is discharged into the river without overloading the sewage system. The project demonstrates that architecture can integrate with nature, provide comfort, preserve the landscape, and ensure sustainability.

Project description by Architekti DRNH

The newly constructed „Diorit“ residential building was developed on the site of a former quarry, on abandoned plots located at the border of the Brno districts of Komín and Bystrc, in the narrow river valley of the Svratka River. Nature gradually transformed the long-abandoned industrial environment into a dynamic ecosystem, including rare species that did not find suitable conditions in the surrounding landscape.

The architects independently recognized the site’s potential and designed a residential building project that transforms the brownfield, removes environmental burdens, and simultaneously respects the natural environment and the high biodiversity of the location. They convinced local authorities, state administration, and the investor of the project’s relevance, and together successfully completed the development, named after the mineral historically extracted on the site. The building represents an effort to limit urban sprawl at the expense of open landscape and to promote sustainable urban development using a former industrial area.

The building is set in a varied terrain and its form responds to the surrounding conditions. The front section functions as an acoustic barrier along the street and smoothly transitions into the courtyard part, which follows the morphology of the quarry’s original rock walls with steep slopes and terraces. The architecture responds to the local topography – a combination of natural plaster shades, milk-profiled glass façades, smooth curves, and dramatic breaks, complemented by extensive greenery, creates a harmonious whole reflecting the integration of the building into the former industrial quarry environment reclaimed by nature. The landscape design respects the vegetation of the rock walls, preserves parts of naturally occurring greenery, and supports biodiversity through new plantings. This creates habitats close to nature for birds, insects, and small mammals, strengthening the stability of the local ecosystem. A recreational green roof park on the underground garage roof seamlessly connects with the vegetation on the rock walls and creates a pleasant microclimate within the block.

The spatial diversity of the building allows for a mix of exclusive residential apartments and premium investment opportunities. The building offers apartments ranging from studio apartments with a kitchenette to four-room apartments with a kitchenette, mostly oriented towards the shared park via green terraces, providing unique views of the quarry’s natural environment. Spacious apartments in the end sections of each floor also feature extensive roof terraces overlooking the opposite side of the Svratka valley. The building also includes shared amenities with a reception area and commercial units with services. All apartments are equipped with a smart home server controlling the ventilation system, underfloor heating, cooling, and other optional systems.

The vertical load-bearing structure consists of a system of transverse and peripheral reinforced concrete walls and sand-lime brick blocks, with monolithic ceilings. The underground garage features a monolithic frame, allowing the natural rock walls to remain exposed. The layout combines stair sections with corridor arrangements, and a glazed corridor facing the main road also functions as an acoustic barrier. The interior design pays particular attention to the architectural arrangement of shared spaces, with emphasis on easy orientation through color differentiation of sections.

In terms of energy efficiency and water management, the building is highly sustainable, classified as Class A, with low operating costs and environmentally friendly features. The building is heated and cooled using heat pumps drawing energy from deep wells. Rainwater is collected in underground tanks for garden irrigation, while excess water during heavy rainfall is discharged into the river without burdening the public sewer system. The project demonstrates that architecture can respect the natural environment, provide comfortable living, protect the landscape from excessive urban pressure, and deliver both aesthetic value and long-term sustainability.
