Just like the entire Rhomberg Group, Rhomberg Bau GmbH has achieved a great deal and left its mark in the form of stunning buildings throughout Vorarlberg and the rest of the world.
Rhomberg continues to focus on wood: with ZERO, the traditional family business now also offers turnkey sustainable building concepts to customers from industry and commerce. In the field of serial renovation with wood, Rhomberg Bau sets new standards together with the German housing company LEG Immobilien and founds Renowate. The EDGE Südkreuz Berlin, built with Rhomberg Bau participation, achieved the highest value in the history of DGNB certification and received the platinum award.
Vienna grows: Rhomberg Bau Wien, which has been an independent company since this year, strengthens itself with the renowned construction company Ing. Prath Ges.m.b.H. Nfg. KG. Rhomberg is thus growing by 24 highly qualified employees in the federal capital.
The company continues on its path towards digitalisation and the circular economy: in March, the state-of-the-art asphalt mixing plant of the associated company MIGU goes into operation, and a new, fully automated wet processing plant is built in the company's own Resource Centre. Rhomberg Bau is also strengthening its activities in the energy sector with "Rhomberg Energie".
The revitalisation of the prestigious Funkhaus in Vienna has begun: 21 new, modern flats are being built in the first construction phase. The construction specialists are also active in the home market of Vorarlberg (Schwarzen residential quarter, Alberschwende; Chalets, Furx; Posthotel Taube, Schruns), in Switzerland (Mulino Lustmühle; St.Gallen) and in southern Germany (Hünistraße development project; Friedrichshafen).
With the FlexFix wooden modular flooring and DenkMalNeo, an expert for the restoration of listed buildings, Rhomberg is expanding its portfolio as a full-service provider with specialised partners. The company's own Resource Centre Rheintal is being consistently developed into an environmental service centre.
Wood-system construction, lean-management, flexible floor plans - simply different: Rhomberg sets up the WoodRocks Bau GmbH. With the two "spots" Bud and Terence, the business ventures further into digitalisation and tests where robot dogs can provide support on construction sites. Rhomberg is once again awarded the title of "family-friendly business" and receives recertification from Ökoprofit. With the apartment configurator, customers of the construction company can now plan their apartment in advance on their home computer.
The first Coliving.Villas welcomes residents and offers them living and working in one. Construction of the Bäumlequartier starts in Lochau. The Vienna branch moves into the self-built office building on Gertrude-Fröhlich-Sandner-Strasse near the main train station. The first micro-apartment building complex DAVID is built in Roßmähder, Dornbirn. And meanwhile, Rhomberg has completely switched its working methods to RHome, the digital collaboration platform.
Rhomberg takes over the Zechwald site in Lindau and sets up its German headquarters there. In Wolfurt's Lerchenstrasse, a sensational innovation project is launched: For the first time, two largely identical residential buildings - one made of wood and one a solid construction - are built and compared. On the Rheintal autobahn, Rhomberg Bau puts the Bodensee Hörbranz GmbH service station into operation. And in Ilanz, Switzerland, the MACAU shopping world opens.
Milestones include the construction of the Serviced Apartments SMART ments business Vienna main station, the completion of the residential project Atrium Wohnen in Kempten (DE) and the housing development FLOW in Wädenswil (CH) as well as the start of the timber-housing campaign in Vorarlberg.
The company celebrates its 130-year anniversary.
