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

In a sunny, panoramic location on the southern outskirts of Vienna, in direct proximity to 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 a unique piece, each with its own character and private outdoor space.

From a well-designed 1-room studio with a small garden to a spacious 5-room penthouse apartment with a spectacular panoramic view over the Vienna Woods - hil\side 23 offers the right solution for every phase of life. The adventure garden “Arabellas Garten”, 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 is capable of achieving ÖGNI Pre-Check Gold Standard according to the assessment carried out.

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