Who we are

STONE is an established construction company with a team of around 50 employees in the heart of Lower Austria. We therefore build mainly in Lower Austria, Vienna and Burgenland. For years we have been one of the most dynamic companies in the construction industry – you may know us under the name DASCH. In 2021, we renamed ourselves STONE Exklusiv Bau as part of our new brand identity.


  • Single-family homes
  • Renovations and extensions
  • Restorations
  • Garden design
  • Facades

You’d like to know what sets us apart from other construction companies?

  • We give ourselves enough time for thorough planning.
  • We take responsibility – at the building site and beyond.
  • Our buildings aren’t run-of-the-mill. We give your construction project your own personal signature.
  • We focus on quality and durability.
  • We are triple ISO-certified: ISO 9001 quality management, ISO 14001 environmental management and ISO 45001 occupational health and safety.


We want more than just great houses. We want satisfied customers – and great houses.
Building a house is a very personal matter. After all, your dream home will accompany you for the rest of your life. For this reason, we give ourselves all the time it takes to design your home, your future living space, together with you to your own individual specifications.
The professionals on the STONE team are not only excellent engineers and craftspeople. Above all, they’re good listeners.

With STONE, you can take the finest quality and ongoing support for granted. We rely on long-term relationships based on trust and respect. For our customers this means that we don’t just build or renovate your home and then vanish. Your satisfaction with your house, your apartment or your garden is still important to us, even after the construction project has been completed. Naturally, this sense of responsibility also extends to our employees: measures toward occupational safety, further training, and support after parental leave are all essential components of our mutual success.


Over its 13 years, the STONE construction company (DASCH until 2021) has acquired an outstanding reputation as a specialist for single-family homes in the premium segment.
The firm was founded in 2008 by Musa Gürleyen, who still leads it today – with head, hands and heart.
Since rebranding, it has been operating under the name STONE since 2022.

We think ahead

No half measures: when you work with STONE, you have the guarantee that won’t be left behind halfway.
This applies right from the planning phase up until the completion of your home, including all the peripherals, and afterwards.

We’re always looking at the big picture.

  • With our Sissi Carefree Package, we also take care of the submission of documents and administrative procedures.
  • As general contractor, we coordinate all the trade subcontractors involved in the project.
  • If you wish, we will also help you plan and design your garden.
  • The same standards apply to our trade subcontractors: fixed price, fixed date and guaranteed completeness!

Building with STONE

Have you always wanted to realise your building dream, but haven’t had the time? You’re worried about the effort and the expense?
Even afraid of sleepless nights? We take care of your worries!

Submissions, reports, building authorities – we look after everything.
The STONE Sissi Carefree Package includes all administrative procedures and deadlines.
Once you’ve commissioned us as general contractor, we take responsibility for the coordination of all trade subcontractors involved in the project. The big advantage for you: you have only one contract partner and one contact person.
We also guarantee you a fixed price – and you can rely on it. You can sleep peacefully knowing you won’t pay one cent more for the agreed services. We also guarantee you a fixed completion date for your new home – so you can prepare your move in peace. And we guarantee completeness, an obligation which means we forget nothing when planning and completing your house. And that’s a further guarantee of your fixed price.

You don’t have much time?
You don’t need any.

With the Sissi Carefree Package, we take – almost – everything off your hands.

ISO certifications

Our quality management systems

Only a small percentage of construction companies in Austria can boast three ISO certifications – STONE is one of them! For us it was only logical to certify the areas of safety and the environment at the same time as quality management. After all, the successful organisation of the two areas is the prerequisite for the highest quality.

ISO 9001 – Quality management: defines clear, transparent quality standards.

ISO 14001 – Environmental management: defines standards for environmentally friendly construction processes.

ISO 45001 – Occupational safety management: if you visit the building site during the construction phase of your house, you will see that we take the highest possible safety precautions for you, our employees and our partner companies. This is what we commit to under the ISO 45001 certification, and it is more the exception than the rule in the construction industry.

You can find more information about the individual certifications on the website of the certification agency Bureau Veritas » www.bureauveritas.de


Don’t worry! We’re here to help with anything that might be unfamiliar to you. Guaranteed by over 1,000 projects.
