The neighborhood development at Kempelenpark in Vienna’s 10th district is a classic brown-field development of a former Siemens site.

The aim of the project, which was taken over by STC in 2019, is the climate-efficient redensification and unsealing of the area as well as the creation of more public green space for the residents of the district.

The focus of this project is on creating high-quality space for living, working and spending time in combination with a focus on sustainability and climate resilience.

STC Development is responsible for the neighborhood development across all construction sites in the Kempelenpark project.

The privately financed building plots A1, B2, B3 and A3, on which several innovative, climate-efficient commercial and residential buildings as well as a kindergarten are to be built in future, will be further developed by STC.The subsidized building plots will be further developed by the non-profit developers Heimat Österreich (building plot A2), WBW-GPA (building plot A4) and Frieden (building plot B4) once the City of Vienna’s quality assurance process has been completed.

The WILDQUELL-NORD project area with a total area of around 12,840 m² is located at Wiegelestraße 12 in Vienna’s 23rd district and was purchased by STC in December 2021. Prior to the demolition carried out in winter 2022/2023, the site was occupied by a vacant and dilapidated office building including logistics halls dating back to 1970.

The project is currently in the rezoning phase and provides for the construction of around 32,300 m² gross floor area with mixed use (residential and commercial).

STC is developing the “PIER05” project in Vienna. With PIER05, a lighthouse project for Seestadt Aspern is being built on a site area of 4,090 m² directly on the lake.

The planning team Zechner & Zechner ZT GmbH / StudioVlaySteeruwitz ZT-GmbH / DnD Landschaftsplanung ZT KG emerged as the winner of the realization competition, which was completed in March. The design envisages a building ensemble consisting of 4 structures. The tower positioned to the south has a height of 82m, the northern high point a height of just under 60m.

The planned distribution of use is 25% commercial and 75% residential. The ground floor will mainly be used for restaurants. Above this, flexible commercial space and modern living space will be created. Technical and storage areas will be located in the basement. The parking spaces required for the project are secured on a neighboring property.

The project meets the highest standards of sustainability and energy efficiency. Green roofs, façade greening and PV elements are integral components of the architecture. The open spaces are completely car-free and therefore offer the highest quality of stay.

STC has developed and realized a 19-storey residential tower with around 370 apartments for Art-Invest Real Estate in the immediate vicinity of Vienna’s main railway station.

The project was planned by Delugan Meissl Associated Architects. The Metropolitan aims to meet the need for modern, urban living space.

The focus of the planning was on the creation of high-quality small apartments, which enable efficient use of space thanks to the optimal room layout. In addition, tenants are offered attractive common areas such as a kitchen lounge, a fitness room with an outdoor sports area and a roof terrace with a magnificent view over Vienna’s city center. The commercial space completes the offer.

The central location with excellent connections to local and long-distance public transport in the immediate vicinity of the city center, the cultural facilities and the wide range of leisure activities on offer in the Belvedere district round off the project’s overall offering.

STC hasdeveloped and built a six-storey residential project with a total of 147 rental apartments and 258m² of commercial space in Vienna’s 22nd district, Erzherzog-Karl-Straße.

The compact apartments are ideal for singles and couples, but small families will also feel at home in the larger, light-filled apartments. Each residential unit has its own outdoor areas that invite you to relax.

The building is temperature-controlled via component activation, with heating and cooling being generated using a water-to-water pump. In this way, a pleasant indoor climate can be achieved through a sustainable solution.

The future-oriented implementation enables cost-conscious tenants to experience the potential of an innovative living environment.

The Kubus office building, designed by architects Baumschlager Eberle, is part of the TownTown project development and serves as a forward-looking office location in Vienna for STC and the ILF Group, among others.

By focusing on sustainability, resource conservation, energy efficiency and careful planning, we were able to achieve maximum comfort for the building users. With the Kubus office building, we have constructed an ultra-modern and innovative office building which, despite the building’s intelligence, responds to the user wishes of our colleagues and creates a consistently pleasant working environment.

We are proud to have realized the first office building in Austria to be awarded the GOLD medal (now upgraded to PLATIN) by the “German Sustainable Building Council”.

The ORBI Tower is the successful completion of the TownTown project and is a striking eye-catcher on Vienna’s main north-south and east-west traffic axis. The ORBI Tower can be seen from both the A23 and the A4 over long distances and, together with the Wien Energie Tower, forms the south-eastern high-rise gateway to the center of Vienna.

Its streamlined basic form, designed by architects Zechner&Zechner, contrasts with the surrounding cubist buildings and allows maximum flexibility in the layout of the office space.

In the course of planning and construction, the focus was on the future of work (New World of Work). The modern working environment achieved through a multitude of technical refinements impresses with its efficiency, sustainability and user comfort and was awarded the PLATIN medal of the building certification ÖGNI (Austrian Sustainable Building Council).

The modern, multifunctional TownTown business park in Vienna comprises 19 buildings and offers the highest standards for offices, stores and leisure facilities. The special feature of this business park is the fact that the entire area of 31,000 m² was created by building over the U3 subway line and the U2 service station.

The optimal infrastructure is complemented by excellent public transport links, proximity to the international airport and the interface between public and private transport. All buildings in TownTown are heated and cooled using building component activation, with the necessary cooling being generated locally.

The Wien Energie Tower and our Kubus office building have been awarded the GOLD and PLATIN medals from the DGNB (German Sustainable Building Council) and ÖGNI (Austrian Sustainable Building Council).
