Hotel Schloss Montabaur

GermanyGermanyCompany Name: G+K Trockenbau GmbH

Project description

The Schloss Montabaur is the Headquarters of the ADG, the academy of German cooperatives (Akademie Deutscher Genossenschaften) which has been a nationwide partner of the cooperative banks and their companies for over 40 years. In the year 959 the castle was mentioned in a document for the first time. Next to the castle is the new guest house “Coblenz” that belongs to the 4-star hotel company of the ADG. The unconventionally designed elliptical construction body offers over 2 floors, 77 high-quality exclusive designed double rooms. Every room is formed differently. The generous atrium is open over 2 floors and is covered by a large 300 square metres glass roof. The very specific architectural ideas could only have been realized with perfectly installed drywall constructions and the highest level of craftsmanship. As a result, the hotel is an outstanding example in the German hotel scenery.


G+K Trockenbau GmbH

The company “G+K Trockenbau GmbH” was founded in 1992 by the today’s owner and manager, Mr. Michael Koch. Today the company is one of the biggest dry building contractors is in Koblenz. Beside the Company “G+K Umbau und Sanierung GmbH” and “G+K Putz – Farbe GmbH” still belong to the G +K company group. From the small beginnings the contractor has developed to one of the biggest companies in this area and has drawn attention to itself by intelligent and practical ideas.

Key Achievements

  • The invention and implementation of new solutions with Saint-Gobain products were one of the key achievements
  • Sloped glass roof which couldn’t bear additional load
  • Highest demands for perfect surfaces to prevent strikes of light
  • More than 300 holes had to be mounted into the elliptical wall for glass and illmumination elements

Key Challenges

The demanding creation & implementation of the unusual ideas of the architecture were very challenging. Most drywall constructions in the building were realized differently to the former specification. The contractor suggested Saint-Gobain products in order to meet the highest demands of sound insulation and fire prevention. A lot of technical know-how and craftsmanship were needed for the implementation of the different components with different demands for fire prevention and sound insulation. The highest level of craftsmanship was needed in order to create and realize the more than 150 openings for the fixed glazing in the atrium into the elliptically shaped plasterboard wall. The wall finishing was executed according to the highest German standard Q4 in order to prevent streaks of light on the walls.
