The aim of the new urban planning of the area of the Museum of Polish History is to reorganise the whole area from an urban and landscape perspective, including the historical Lazienki Park, the historical heritage of Finnish cottages on Jazdow Street, the park areas near the German and French embassies and the slopes and the central part of the Os Stanislanowska.

The project establishes a new network of footpaths and pedestrian paths linked to the main existing ones. The coverage of the Trasa Łazienkowska motorway provides the area on which the new park is located. The landscape project works with the directions of the different axes of the area. The intersection of the axis of the castle (Museum of Contemporary Art) and the axis of the new museum creates a new square. This square becomes the largest public space in the area. The rest of the paths and roads, together with small squares, intertwine generating a whole system of spatial relations.

The project works with the vegetation in an architectural way, using different species depending on their colour, size and smell. The park is conceived as a set of small fragments so that it can be developed little by little according to the stages of the project.

In terms of the architectural proposal, one could say that the building is a compact volume that establishes a dialogue with the castle. The project is to create a new profile on Trasa Łazienkowska, linking it to that of the castle and the trees that now give the site its identity. In this way, the volume of the building becomes very rich on the roof. The creation of a topography will produce a new landscape on the skyline. This topography is accessible to the public in some areas such as the restaurant terrace. The shape of this roof volume is directly generated by the interior space. The spatial perception of each point of the exhibition rooms is linked to the events of history in that period, so that the whole experience is a route with open or closed spaces, with low or high ceilings, large or small spaces, establishing a dialogue with the body, fantasy and memory of the visitors.

The common areas of the building and the entrance lobbies are different from each other, creating an ‘internal square’ and ‘streets’. These spaces are interwoven with each other, with the roof and with the surroundings: the skylights produce diagonal visions between the building and the sky, and the external paths are linked to the internal ones.

An important point is the material appearance of the building. On the outside, the façade is made of aluminium with a slightly reflective appearance. In this way the building subtly reflects the colouring of the trees at different times of the year. Inside, each skylight can have its own finish depending on the gallery and the time of year. Some of them are gilded to give a warm appearance to the interior.
