The plan was made for the steep hillside of Tahitótfalu. The commission was for the expansion of an existing small holiday building. The design was made exciting by the building's steep location on the plot and the tightness of the plot. The extension is connected to the existing building but offset from it, while the roof ridge line continues from the original building's ridge line. The gable end of the building has received a huge glass surface, which offers a wonderful view of the Danube embracing the Szentendrei Island.
