"We were ’hooked’ right from the first drafts. The building is airy, very comfortable and communicative. And everything has been built according to our needs. Our decision in favour of TRIOTOP and the building 'Alpha eins' was spot on. We’re now already looking forward to expanding our rented/leased spaces, which the company Friedrich Wassermann will build for us in the same architectural design and according to the same first-class quality."

Thomas Haslinger, managing director of publiCare GmbH, one of the leading home care companies in the German-speaking countries, is already busy planning the company’s future expansion at TRIOTOP Cologne.

"From the very first moment, everything was just right for us: swift planning and implementation, adherence to schedules, openness to unusual solutions and an extremely flexible way of dealing with our wishes. However, the really special thing about it is – the ’Wassermänner’ have built it with a great deal more heart and flair and have thought of great things, for instance, the beautiful roof terrace or the elaborately designed recreation room. Our building ’Nessie’ and the park have been developed in detail in a sophisticated way and a lot of love has been thrown into it. We and our visitors notice it daily – and we are grateful for this."

Dave Sieber and Peter Fröhlich from Alere GmbH appreciate their building "Nessie" and TRIOTOP as much as the supervisory services of the company Friedrich Wassermann.

"We had the advantage that we were able to incorporate our requirements into the planning still at the very early building stage, in particular the cabling and wiring was carried out according to our high standards. The clever use of space on which we were able to have a say allows for rapid communication between employees. The high standards of security are also important to Sony. We are naturally pleased about a great view over the park and the tranquillity in TRIOTOP. And with the Bistro “FRITZ“, there is now a really great catering service."

Bernd Rauch, Senior Manager Field Operations of Sony Professional Solution Europe, Sony Professional Solution Europe, would opt again for TRIOTOP and "Zwitschermaschine" as the company’s main office.

"Precisely the right location for our communications agency, surrounded by nature and with good transport connections available. Here we can focus on our work in peace. From here, we can reach our clients well in Cologne’s city centre and in other locations across the country."

Sabina Janssen is pleased in every respect with the main office of her agency Janssen Text & PR in Zwitschermaschine.

"Location, architecture, pure nature. TRIOTOP – that’s a recipe in which all the ingredients are right. Furthermore, L & D as operating company of the Bistro "FRITZ" at TRIOTOP is focusing on the future issue of sustainability just like the company Firma Friedrich Wassermann. That’s just perfect!"

"We are constantly impressed how we as ’small scale tenants’ are treated by the company Friedrich Wassermann. They are always ready to listen and respond very promptly to our wishes as tenants. The extraordinary architecture is of course also great, the location right at the heart of nature, everything within good reach. The positive resonance of our visitors, whether they are patients or trainees, consistently confirms our choice. We have an identity with ’our’ location!"

Annette v. Hajmasy and Jürg Stuck of Jürg Stuck Zahntechnik GmbH for good reasons feel that they are in the best hands at TRIOTOP.

"At TRIOTOP, we found the ideal mix between functional and attractive offices, a pleasant and tranquil location and good transport connections. From the very first visit – still at the very early construction stage – to the moving-in itself took only six months. The cooperation with Friedrich Wassermann worked extremely well during this planning and the moving-in phase. Already two years on, we feel comfortable at TRIOTOP in every respect. Here our IT specialists find the necessary tranquility and our service employees have fast access to our customers. The location is ideal for our company."

Pleased right from the start: Ralph Friederichs, managing director of Cyberdyne IT GmbH

"The architecture is very sophisticated and the configuration of the rooms is first-class. The spaces have been tailored precisely to our requirements and our agency is able to grow at the location. We are working right at the heart of nature with a view overlooking the biotope and are connected to the urban life with the motorway and city not being far away. And last but not least: the price-performance-ratio is correct. What more do we want?"

Ralf Heber together with his partner Oliver Link for good reasons opted for "Zwitschermaschine" as the location for communications agency HEBER.LINK.

"Architecture meets nature! The concept of TRIOTOP is well-thought-out and successful. And the ambiance suits our business area of corporate consulting perfectly. We appreciate our pleasant neighbours and above all, the tranquility of nature as an antithesis to the at times hectic daily working life."

Michael Buttermann with his consulting company Buttermann Human Consulting InterNational completely comfortable in TRIOTOP.

"TRIOTOP with its conceptual combination of nature and first-class architecture is the ideal location for our Green Building "etrium". A sustainable building at a sustainable location."

For Carsten Petersdorff, managing director of Ecofys GmbH, which "advocates a sustainable energy supply for everyone", not only the "etrium" but also the TRIOTOP location is an advertisement.
