Pál Luczenbacher, who also earned the noble name of "Szobi", built the Danube-side summer residence for the family between 1902 and 1907 based on the plans of Ignác Alpár. Presumably the Luczenbachers first built a neoclassical mansion, which Alpár extended and rebuilt in the typical neo style of the turn of the century, which combines neo-Baroque and Art Nouveau elements.

One of the aims of the current monument renovation is to restore the exterior and interior of the neo-Baroque Alpár castle. Also to create a modern dormitory (about 30 boys and 30 girls) that meets the current and future needs. The former neoclassical mansion has been converted into a western ground floor wing with common rooms and a chapel, while the eastern L-shaped two-story wing houses the dormitories and a group of service rooms and bathrooms.

We restore the separation of the Luczenbacher wing of the street front outbuildings and propose to remove the intrusive addition. This ground-floor wing will be restored to its original form, with an empty attic space, the Alpár façade architecture, and a new heating centre, a warming kitchen (see kitchen technology) and a dining room. In the other separate building on Árpád Road ("C" building), service apartments will remain in their original form, renovated with an empty attic.

The key issue for the technical implementation of the whole reconstruction is the location of the extension of the dormitory floor plan in the "B" wing of the building on Árpád Road. An important architectural decision is the relocation of the main entrance from the former boat station from the Luczenbacher Square to the Szent László Square, with the interruption of the street front wing gate. This solution will create a direct spatial link between the parish church and the mass of the castle, and between the churchyard and the castle garden.
