Gimnazjalna Street Bydgoszcz
Architecture, Interiors
Gimnazjalna Street is Rise.Design's first major urban rehabilitation commission and the project that established the studio's reputation as a developer-facing practice. Three abandoned five-storey historic buildings at ul. Gimnazjalna 4, 6, and 8 in central Bydgoszcz — ruins with holes in floors, deteriorated roof slabs, and junkies occupying the upper storeys — were transformed into a vibrant mixed-use quarter spanning 4,000 square metres across four floors and a 300 square metre rear courtyard.
The client, Moderator, is one of Poland's major developers of building rehabilitations. The relationship began when the company's president met Diogo Leitao through an unnamed business agent in 2014, with Moderator approaching directly for the Gimnazjalna commission in January 2015. The commission covered the full design cycle: concept, technical documentation, construction supervision, and completion through 2016.
The design vision was a layered mixed-use ecosystem: three buildings, three identities, but a single unified street presence. Building I at Gimnazjalna 4 provides residential apartments in three sizes — 40, 80, and 100 square metres — with fold-down beds and modular kitchens that support both permanent occupants and short-term use. Building II at Gimnazjalna 6 becomes a hostel with studio apartments. Building III takes a horizontal and vertical enlargement to match Building II and houses offices, creative workspaces, a showroom, and a photographic studio.
The ground floors across all three buildings activate the street with pub, restaurant, cafe, wine shop, gym, laundry, bike room, conference room, art workshop, and language school — a full urban programme that made Gimnazjalna one of the most popular streets in the city. Patchwork Eames-style chairs became the signature furniture piece of the residential apartments; Gothic-arched windows in penthouse units and exposed roof trusses with skylights in attic apartments exploit the specific heritage conditions of each building level.
The signature structural intervention lowered the basements of Buildings 1 and 3 by approximately two metres, converting 90-centimetre storage cellars into full-height commercial spaces with street-facing windows. This excavation created the atmospheric vaulted rooms that now house Zaklad — a bar and live music venue with exposed arched brick ceilings that became one of Bydgoszcz's most recognised cultural spaces.
The interior design language throughout is industrial-chic meets cosy warmth: exposed concrete ceilings and raw structural elements combine with wood finishes, patterned tiles, warm Edison-bulb lighting, and living tree trunks incorporated as interior elements at ground level. Winosfera wine shop, NaPizza restaurant, Burger Park, and the Zaklad live music bar continue to operate as the anchor venues that define the street's character.
The 300 square metre rear courtyard was redesigned as a shared outdoor living room, with concrete-look stone steps arranged in an auditorium configuration for outdoor concerts and communal events. A restaurant in Building III had a separate garden area.
The neoclassical facade restoration across all three buildings — cornices, window surrounds, pediments, decorative mouldings in warm cream and white tones — reunifies the street elevation and signals the quality of what lies within. The colour palette was chosen to perform across seasons: the warm tones that feel celebratory in summer light take on a quieter dignity against overcast autumn skies, proving that the restoration was designed for Bydgoszcz's climate rather than for a single photogenic moment.
The JAHR building with its distinctive yellow-painted facade stands alongside the lighter grey and white buildings, creating a rhythmic variation across the streetfront.
Each building received its own colour identity while the shared cornice lines and window proportions maintain the unified neoclassical composition.
Iron staircases descend from street level to the below-grade commercial entrances, their wrought railings adding a layer of detail that defines the sidewalk experience. Pumpkins on the steps and potted plants at the entries signal the tenants' ownership of the threshold spaces.
The restored ornamental details — pediments above windows, cornice brackets, and decorative mouldings — are best appreciated from below, where the full scale of the restoration work becomes visible against the sky.
Patterned cement tiles recur throughout the project as a unifying material: staircase risers, entrance hallway floors, and commercial interior wall features share the same vocabulary of geometric motifs that bridges the heritage character with the contemporary interventions.
Construction was executed through Rise.Design's own subcontractor network, with specialist firms handling the primary build and delivering custom carpentry and kitchens. The project was completed in 2016 and the outcome affirmed by the tenants who remain.
