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

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

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

From the well-thought-out 1-room studio with a small garden to the spacious 5-room penthouse apartment with spectacular panoramic views over the Vienna Woods – hil\side 23 offers the right choice 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 of encounter 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.

Whoever buys wisely today saves tomorrow. hil\side 23 is exactly that: one of the best addresses in the south of Vienna with excellent long-term residential value.
