Initial perception of the site, especially its smaller size, led us to the conclusion that it is appropriate to choose an expansion of the existing house in the smallest footprint possible, to avoid reducing the garden area and dividing it with another building. That’s why we approached the design of the extension as a garden pavilion or gazebo, which will provide its users with truly seamless and immediate connection to the garden.
At the same time, we placed the entire extension on the plot in a way that it would be concealed from views from public spaces as much as possible, so as not to disturb the overall integrity of the older and newer parts of the house. Therefore, we proposed an extension to the extension. From this phrase alone, it is evident that we did not want to further extend this series of extensions, but rather conclude it with a completely different, yet fitting, structure.
The roof of the extension, with its shape resembling a mushroom cap, gives the new building the character of a „mushroom,“ naturally blending with the existing house, similar to a mushroom growing on a tree. The extension utilizes existing spaces on the ground floor of the building and significantly modifies them, including the load-bearing structure, and relocates the entrance from the south to the north. It aims to maximize sunlight exposure from the southwest and creates the largest possible garden area for recreation in that direction. In addition to the extension, a „northern“ garden was also created, which is more ornamental and forms a kind of „monastic“ garden.

The house, particularly its main living area, is oriented towards the southwest, which poses a significant risk of overheating during the summer. Therefore, this space, along with the adjacent rooms in the annex, is designed based on the principles of the "Socratic house."
To ensure adequate protection against overheating of the interior during the summer, the facade of the main living space is equipped with a significant roof overhang. This is especially important because the southwest sun is lower in the sky during its trajectory, and the shading overhang of the roof must correspond to this.
However, the prominent roof overhang can considerably limit upward views from the interior. To mitigate this impression, the roof overhang has a smooth, organic shape, so under favorable lighting conditions, it appears to blend into the sky when viewed from inside.

Photovoltaic panels are installed on the annex roof, and in conjunction with the heating source, they ensure a very economical operation of the house in terms of resources.
The house also efficiently uses rainwater, and the overall water management system is designed so that municipal water is the last resource where feasible.
