UNDER ONE ROOF - Student Life in a multilevel space. Dormitory at Juliana Tuwima Street, Gdańsk - Aniołki.

Project idea

Concept of a Student Dormitory, encompassing residential spaces, recreational areas, a shared kitchen, study and workspaces, as well as a café and a gym. The facility is designed to be located in the Wrzeszcz Górny – Aniołki district of Gdańsk, at the intersection of Juliana Tuwima and Śniadeckich streets, near numerous universities and green areas. The project's goal is to provide functional and modern solutions that support both academic development and students' daily lives. The common areas are designed to encourage interaction, the exchange of experiences, and relationship-building, thereby fostering a friendly student community. A key aspect of the project is the harmonious integration of the building into the urban fabric, creating a balance that both honors the city's heritage and draws inspiration from the dynamically developing Gdańsk. The student dormitory is envisioned as a modern, comfortable space that supports both academic growth and the social lives of young people.

Project description

The project proposes a new model of student housing that responds to the challenges faced by contemporary dormitories, while also addressing broader issues facing modern cities. A key concept is the idea of the layered city - a spatial approach where different functions and environments intersect across various levels, creating richer and more functional living conditions.
Of particular importance are rooftops, which can serve far more roles than traditionally imagined. Transformed into green terraces and gathering places, they contribute a new dimension to the urban landscape. These rooftop spaces offer opportunities for relaxation and activity, providing a breath of fresh air from the intense pace of city life while fostering social connections above the urban noise.
In the context of student housing - where private space in individual rooms is often very limited—the creation of attractive, open common areas, including on rooftops, becomes especially significant.

Technical information

The building is founded on a 50 cm thick monolithic foundation slab made of C25/30 concrete, directly supported on a layer of native bearing soil. Beneath the slab, there is a 10 cm layer of lean concrete and a mechanically stabilized crushed aggregate base to ensure proper load transfer and stability.
The load-bearing walls are made of SILKA calcium-silicate blocks and work in conjunction with a system of reinforced concrete columns, beams, and tie beams to carry floor loads. In stairwell areas, reinforced concrete walls are used to provide additional structural bracing and rigidity.
Above door and window openings in masonry walls, prefabricated reinforced concrete lintels with cross-sections of 30x30 cm are used. These elements are made of C25/30 concrete and reinforced with B500B steel.
The beams are monolithic reinforced concrete elements constructed from C25/30 concrete and reinforced with B500B steel. Depending on the span, they have cross-sections of 30x40 cm (for 6.30 m spans) or 30x50 cm (for 10.00 m spans). The main reinforcement consists of 4Ø16 to 4Ø20 bars, and stirrups Ø8 are spaced every 15 cm, with closer spacing of 10 cm near supports. The beams rest on columns arranged in a 6.30 x 10.00 m grid.
The floor slabs are monolithic reinforced concrete, made with C25/30 concrete and B500B steel, with a 3.0 cm concrete cover. Over enclosed rooms, the slab is 20 cm thick, one-way reinforced, and spans 6.30 m on masonry walls. It includes Ø12 reinforcement spaced every 15 cm at the bottom, and Ø10 every 25 cm at the top near supports, with 25x25 cm tie beams around the perimeter. Over open areas, the slab remains 20 cm thick but is two-way reinforced and supported by concrete beams, with Ø12 bars every 15 cm at the bottom and Ø10 bars every 25 cm at the top in both directions. The garage slab follows the same thickness and reinforcement scheme as above, using one-way reinforcement on a 6.30 m span, and includes reinforced concrete beams with cross-sections of 40x50 cm and 25x25 cm tie beams.
The roof slab is designed as a 20 cm thick monolithic reinforced concrete structure, functioning as the final floor slab and one-way reinforced. On top of this slab, a layered system is placed according to the architectural and technical design, incorporating an extensive green roof system. This includes vegetation layers (such as sedum and rolled grass), along with drainage, insulation, and waterproofing layers that support plant growth and protect the structure.
Monolithic reinforced concrete columns, each with a cross-section of 30x30 cm, are placed on a 6.30 x 10.00 m grid in large open areas that lack structural walls. These columns are reinforced with 4Ø16 main bars and Ø8 stirrups spaced every 15 cm, tightened to 10 cm near beams. They are made of C25/30 concrete and B500B steel.
The internal stairs are designed as monolithic reinforced concrete elements. The stair flights have a thickness of 15 cm, while the landings are 20 cm thick. The stairs are reinforced with B500B steel and supported by the surrounding masonry walls.
