Your box seat in the sun | 1230 Vienna, Breitenfurter Straße 434

In a sunny elevated location on the southern outskirts of Vienna, in the immediate vicinity of the Maurer vineyards and the Lainzer Tiergarten, hil\side 23 is being developed as one of the most attractive new-build projects in the green south of Vienna.

28 free-financed owner-occupied apartments in two elegant building volumes arranged harmoniously around a shared piazza – each apartment is a unique piece, each with its own character and private outdoor space.

From a well-thought-out 1-room studio with a small garden to a spacious 5-room penthouse apartment with spectacular panoramic views over the Vienna Woods – hil\side 23 offers the right solution for every phase of life. The experience garden “Arabella’s Garden” designed by a landscape architect with pergola and quiet oases gives the project a special atmosphere and creates a place for encounters and communal living.

The energy concept sets new standards: air-source heat pump, photovoltaic system and green flat roofs ensure permanently low operating costs. In addition, the project has been assessed as capable of achieving the ÖGNI Pre-Check Gold standard.

Those who buy smart today save tomorrow. hil\side 23 is exactly that: one of the best addresses in the south of Vienna with excellent long-term residential value.
