Diuna – for the well-being of people and nature.


Diuna embodies a vision of designing office spaces, that are closer to the city, the user and the community. Facilities in which communal spaces offer respite, are surrounded by nature, and where systems are managed wisely and efficiently,so as to minimise the impact upon the environment.

Human aspect


New reception areas

The new reception areas are filled with elegant spaces, organic shapes, high-quality materials and art.

Conference centre

A fully flexible and adaptable space allows for the organization of conferences of up to 100 people. It can serve as an ideal room for yoga classes.

On-site facilities

A Lux Med clinic, a shop, a café and a parcel point available directly within the complex.

Facilities for cyclists

New above-ground parking spaces and repair bases, while in the underground car park, parking slots, convenient showers, and contemporary changing rooms.


1,300 parking spaces, including spaces with charging stations for electric vehicles.

Integration into the environment

The modernised complex is completely barrier-free, fence-free, fully open to the surrounding area and perfectly integrated into the urban cycling network.

Open workspaces

The new reception areas and flexible adaptable spaces in the building make it possible to work very freely as a co-working space in addition to the tenants’ own offices.

The environment

The revitalisation of the Diuna complex is based on the idea of a circular economy. During thebuilding audit of the complex assessed the possibility of reusing finishes and structures of the buildings, together with an assessment of their embedded carbon footprint. All of the greenery from the original square has been distributed to the tenants, some materials have already found their way into the project, the remaining stored elements are waiting for a second life. In line with the European Commission’s recommendations the project is on track to reducing CO2 emissions to zero by 2050. 

Significant CO2 reductions

Thanks to an independent audit and the implementation of a number of measures improving the energy efficiency of the buildings, it has been possible to achieve a reduction of 31%, which corresponds to a reduction in carbon dioxide emissions of 1,575 tonnes per year. 

Native shrubs instead of a parking

The whole area was transformed by an undulating area covered with native vegetation. As a result the creation of a green dune has been established, which has been planted with 12 species of trees (50 trees) and 96 types of shrubs. This is native shrubbery, important for such projects, all implemented in the spirit of sustainable development. 

A Reduction of Energy Usage

We have introduced a new system of VAV and improved the HVAC system, air flow control and replaced chillers for more efficient ones. 


All upgrades and enhancements are designed to maintain the highest possible quality and receive expert recognition. This is why the various aspects of the transformation and the efforts of the project team are awarded prestigious certification, which are proof of the effectiveness of our efforts.

The complex is devoid of barriers after the modernisation – open to the city, pedestrian and bicycle traffic. New walkways and cycle paths have been created leading directly to the railway station or Marynarska Street.

The cost-effectiveness of the investment is not only measured by economic efficiency – nowadays, a sense of comfort for tenants is equally important in building a business advantage. The newly created park will serve all tenants as a place for meetings, relaxation and recreation.

The once flat patio area has been diversified with hills, increasing the biologically active area and allowing 98 species of native shrubs and 50 trees to be planted.

Paths and water installations meander between the slopes, while comfortable urban furniture creates island-like relaxation zones. Trees, shrubs, grasses and flowers fill the landscape and will provide a good habitat for urban birds and insects.

Previously a concrete car park, it has been transformed into a beautifully landscaped urban garden and the representative frontage of the complex is highly visible from Marynarska Street.
