Modular social and office building project

The building was designed as modular container structure intended for social and office purposes to support ongoing activities.

The project was carried out at two locations – Gdańsk and Strykowo near to Poznań, where an additional photovoltaic system was installed on the roof to support the generation of electricity from renewable sources. The work included the delivery of ready modular containers along with interior installations and equipment.

The building consists of four standard container modules placed next to each other. The middle module was offset compared to the others, creating a varied architectural composition while maintaining a compact building form.
The building is single-story and covered with a system flat roof. Various finishing materials were used on the facade, with a dominant standing seam metal cladding.

Photovoltaic system installation

To improve the energy efficiency of the facility, a photovoltaic system was installed on the roof of the modular building. The installation consists of 77 solar panels with a total capacity of 40 kW, enabling the production of electricity from renewable energy sources directly on site.

The generated energy powers the office and social areas of the building and also supports an electric vehicle charging station. This solution increases the building’s energy independence and reduces reliance on external power sources.

Architectural form

The building form was created by combining four rectangular container modules placed next to each other. The use of an offset middle module allowed for a more varied facade composition while maintaining a compact structural layout.

The building’s exterior combines different finishing materials mounted on a steel substructure fixed to the container frame, including metal panels and vertical facade elements.

Container system

The building was constructed from four container modules
 made using a steel construction system. The container structure consists of a self-supporting steel frame made from cold-rolled profiles.

The floor and roof frames are connected by corner columns bolted
to both load-bearing frames.

Steel floor frames
Cold-rolled, welded steel profiles, with 4 container corners welded together
Longitudinal load-bearing beams for the floor
Steel 3 (s 235) or 4 mm (S 355)
Front load-bearing beams for the floor
Steel 3 mm (S 235)
Cross load-bearing beams for the floor
Ω-profiles, s = 2.5 mm (S 235)
Corner columns
Welded cold-rolled steel profiles, connected with floor and roof frames.
Steel 4 mm (S 275) or 5 mm (S 355)
Roof frames
Cold-rolled, welded steel profiles, with 4 container corners welded together
Longitudinal load-bearing beams for the roof
Steel 3 mm (S 235) or 4 mm (S 355)
Front load-bearing beams for the roof
Steel 2.5 or 3 mm (S 235)
Roof covering
Galvanized steel sheet with double overlap, 0.60 mm thickness

Modular office-social building installation

As part of the project, we carried out the complete installation of a system-based building consisting of four “20” containers. The process included mounting the steel structure, foundations made of B20 concrete, and exterior walls with polyurethane core sandwich panels for excellent insulation.

During the installation, the containers were carefully lifted and positioned on the foundations with high precision. After the installation, the building was connected to essential utilities, including rainwater drainage, fire water tanks, and a sanitary sewage system. Thanks to meticulous execution, the building was ready for use in a short time, meeting all functional and technical requirements.
