New Provostry Extensions and Reconstruction by Studio acht: A Heritage Revival in Prague Castle

The New Provostry Extensions and Reconstruction is a landmark heritage restoration and adaptive reuse project located in Prague 1, Czechia, within the historic grounds of Prague Castle. Designed by Studio acht and completed in 2023, the project carefully restores a Neo-Gothic building dating back to 1877 while introducing contemporary courtyard extensions that reactivate the site for public and commercial use.

Originally constructed as the residence of the provost adjacent to St. Vitus Cathedral, the building was confiscated in the 1950s and fell into neglect during the communist era. The courtyard structures were demolished, and the main residence was converted into barracks. Following restitution in 2016, the property was returned to the Church, opening the door to a sensitive architectural restoration and urban revitalization strategy.

Heritage Restoration and Adaptive Reuse Strategy

The architectural concept centers on historic preservation, courtyard reopening, and contextual contemporary intervention. The restoration carefully returns the Neo-Gothic façade to its late 19th-century character, reinforcing the architectural identity of the Prague Castle complex.

Façade and Interior Restoration

The façade was meticulously restored to recover its historic proportions, materials, and ornamental detailing. Internally, the renovation balances preservation and modernization:

• Restoration of faux-grained historic doors and windows
• Refurbishment and reconstruction of parquet and wooden floors
• Reinstallation of historically consistent tile formats and patterns
• Integration of contemporary glass partitions with minimal steel framing

A key spatial highlight is the main staircase, where a delicate circular pendant light contrasts harmoniously with the strict geometry of the painted wooden ceiling. This gesture exemplifies the project’s broader design philosophy: a dialogue between historical craftsmanship and contemporary architectural clarity.

Today, the building has resumed its original function as the administrative seat of church institutions, including the Metropolitan Chapter of St. Vitus. The adaptive reuse ensures long-term sustainability while preserving cultural heritage value.

Courtyard Reopening and Public Activation

One of the most transformative aspects of the project is the reopening of the inner courtyard to the public. This intervention restores urban permeability within Prague Castle and offers rare panoramic views toward the lower Deer Moat, an area previously inaccessible to visitors.

The courtyard is now designed as a multi-functional civic space, capable of hosting:

• Cultural performances
• Outdoor events
• Corporate gatherings
• Informal public use

The northern edge features a contemporary overlook and a granite-and-bronze fountain, reinforcing the courtyard’s symbolic and experiential dimension.

Contemporary Extensions Within a Historic Context

Two newly constructed extensions occupy the historic footprint of former stables and carriage houses. These structures introduce commercial functions while maintaining architectural harmony with their Neo-Gothic surroundings.

West Extension, Café Pavilion

The west extension, partially extending into the northern basement, is designed as a café serving Prague Castle visitors. It features:

• Vertical openness and generous glazing
• A nearly frameless glass corner emphasizing structural lightness
• Subtle steel-framed glass façade systems
• A dramatic skylight connecting roof and façade

The transparency enhances interaction between interior activity and courtyard life, reinforcing hospitality architecture within a heritage context.

East Extension, Flexible Commercial Space

More compact and introverted, the east extension accommodates retail or office functions. Although formally related to the west pavilion, it maintains its own identity through proportion, enclosure, and spatial configuration.

Material Strategy and Architectural Language

The extensions balance contextual sensitivity with contemporary detailing through:

• Sandstone cladding sourced from the Vyhnánov quarry
• Patinated copper detailing
• Discreet tiled and wooden flooring
• Refined steel-framed glazing systems

A narrow skylight detail creates a dynamic interplay of light and shadow, enhancing interior spatial quality while referencing the historic masonry articulation of Prague Castle.

Outlook and Symbolic Fountain Intervention

The courtyard redesign incorporates an overlook inspired by an unrealized concept by original architect Josef Mocker. This contemporary reinterpretation projects outward from the castle wall, offering elevated views while maintaining structural subtlety.

The adjacent fountain features:

• A granite obelisk
• A bronze-edged basin
• Symbolic water flow from a cross over engraved saint names

Water gradually absorbs into the ground, reinforcing themes of continuity, spirituality, and renewal. A poem engraved in stone further anchors the intervention within ecclesiastical tradition.

Sustainable Heritage Architecture in Prague

The New Provostry project exemplifies sustainable heritage architecture, where restoration, adaptive reuse, and contemporary additions coexist in architectural equilibrium. Rather than replicating historic forms, the design employs timeless geometry, restrained detailing, and durable materials to ensure long-term relevance.

Key architectural themes include:

• Neo-Gothic restoration
• Adaptive reuse of religious heritage buildings
• Contextual contemporary architecture
• Courtyard revitalization strategies
• Hospitality and commercial integration in heritage zones
• Material authenticity and craftsmanship

Through precise restoration and carefully calibrated new construction, Studio acht demonstrates how historic architecture can be reactivated for public engagement while preserving its cultural integrity.
