Philharmonie de Paris

Ile de France Plâtrerie

The Philharmonie de Paris opened its doors in January 2015. The project presented concerns the Symphonic Hall, known as the “Grande Salle”: a state-of-the-art facility for national and international symphony orchestras. The Symphonic Hall is a remarkable architectural feat; an ‘enveloping’ auditorium with a capacity of 2,400 seats, that immerses the audience providing a uniquely intimate listening experience.

The acoustical program called for great clarity of sound combined with high reverberation, as well as significant lateral reflections and a close, intimate feeling. The solution was found in a daring system of floating balconies which creates the intimacy, and the outer shell, which produces the high reverberation. Ile de France Plâtrerie had been commissioned to realise the outer shell of the Symphonic Hall, a completely dissymmetric structure made of plaster, up to 26 metres high, 10 cm thick and including 5,785 cubic sound absorbers of fibrous plaster.

Judge’s Comment: This is an outstanding project that marries technical form with a stunning visual appearance.”

J. W. Marriott


J. W. Marriot is a 5-star luxury hotel. This new luxury hotel offers 585 rooms and boasts an unparalleled location in the heart of the vibrant suburb of Andheri, adjacent to the Mumbai International airport. All 585 guest rooms as well as banquet halls, spa, gymnasium and BOH areas are constructed with international standard acoustic comfort and fire safety. Gyproc drywall was adopted for all internal walls including wet area walls and value added plasterboards e.g. Fireline, Moisture resistance and fibre cement board were also used.

Judge’s Comment: Excellent collaboration between the Saint-Gobain team and the contractor resulted in the installation of an abundance of value-added and technical drywall solutions.”

Gerstheim Catholic Church


On the 25th of November 2011, a short-circuit in the lighting system of the Catholic Church of Gerstheim located in the Alsace region caused a disastrous fire. Major parts of this gothic church were destroyed, including the ceiling and roof structure, and only the walls were left over. The aim of the community was to rebuild the church, identically to how it was before the fire. Werey & Stenger’s task consisted in the reconstruction of the ceiling, i.e. the original vaults of ogival arches. Based on plans and drawings found in the archives, the architect reproduced the plan of the church. Given the complexity and size of the project, Werey & Stenger decided to digitize their part of the project in 3D. This was a highly innovative method which they combined with the traditional technique of fibrous plasterwork. The results are amazing- the original forms have been perfectly reproduced and have also been successfully combined with quite a modern decoration.

Judge’s Comment: “This renovation project used the highly innovative method of modern mould technology to reconstruct the ceiling of this building following a devastating fire.”

Louis Vuitton Foundation


Designed by the American architect Frank Gehry, the Louis Vuitton Foundation falls within the policy of art and culture patronage developed by the Group. A private cultural initiative, its aim is to promote contemporary artistic creation for a wide international audience. This project was a great architectural endeavour in which each stage of construction pushed the boundaries of conventional architecture, and was one of the first BIM projects in France (“Building Information Model”). The BIM has made it possible to create the complex shapes imagined by Frank Gehry, from the design of the building through to the assembly of the different elements on site, and requiring very close collaboration between the different teams working simultaneously with a common 3D model. One of the main challenges was to provide a high acoustic insulation; 71Db required with a critical frequency < 5 Hz, between the technical rooms and the public areas. The contractor had to invent a bespoke solution with self-supporting “boxes in the boxes” made of two layers of Duo’Tech 25 and using Winfix dB suspensions.

Judge’s Comment: This project is a real example of a strong partnership between the contractor, subcontractor and Saint-Gobain’s team to develop bespoke solutions.”

H'ugo's Restaurant Bar Lounge

Malerwerkstätten Heinrich Schmid GmbH & Co. KG

In the Stuttgart city center next to the “Stuttgart 21” project (building of a new through station instead of the existing terminal) a new bar lounge was established in less than two months. This project involved an abundance of creativity as well as technical know-how concerning the necessary sound and fire protection. The optically and technically perfect results are a wonderful example of perfect craftsmanship on a 520 square metre floor. The extraordinary design of the ceiling sculpture was developed in close cooperation with the Rigips technician to provide the various technical requirements which were hidden beneath. Indirect illumination increases the unusual look and feel of the ceiling. Furthermore a 3,500 litre aquarium was built into one of the plasterboard walls. The steel substructure had to be designed to provide for its heavy weight.

Judge’s Comment: This project is truly an example of an imaginative use of drywall systems. The cutting edge and futuristic design of the space was brought to life in particular through the unusual ceiling sculpture with its very "organic" forms made of plasterboards.”

Theater de Stoep

Accompli Afbouw BV

Theater De Stoep consists of two parts; a large theater hall which can accommodate up to 650 people, and a smaller room with a capacity of 200 people. Furthermore the building consists of an office area, a kitchen area, several dressing rooms, technical spaces (theater) and an acoustical decoupled loading dock. This theater is designed with tightly aligned connections between the many different types of planes. The walls were designed in concave and convex forms, which cross the ceilings that are also designed in these forms. This particular design in combination with the great height is made possible by using the specifically engineered supporting structure. All this combined with the required finishing level, the high sound insulation and fire resistance requirements ensured that this was a very challenging project.

Judge’s Comment: This contractor overcame the lack of technical specifications on his project by working closely with the general contractor to design an extremely complex structure for the building interior through a sophisticated Building Information Model (BIM).”

Hochbau 21/BSC-Areal

SA.MA Gipserei + Fassaden GmbH, 8617 Mönchaltdorf

This former spinning mill, a listed historical monument, is approximately 180 years old and shut down its production in 1990. To preserve the valuable building structure and to revitalize it at the same time, a master plan was drawn up to transform the 7-level complex into lofts for living and working. After two years of construction, the building now contains 23 loft apartments, 5 loft-type working spaces as well as 13 studios. The main plasterboard work was applied to ceilings and partitions, as well as technical ducts. The building is Minergie® certified, a renowned Swiss energy label. Among the key achievements of the plasterboard work are the preservation of its historical character and substance of the building while introducing a whole new form of its use, as well as the application of the high fire and noise protection standards to the old building structure. Hochbau 21 is a perfect example of the trend to transform historical, industrial buildings into modern living spaces.

Judge’s Comment: This is an outstanding project completed to a very high technical standard, as well as showcasing a truly innovative use of drywall systems to tackle a complex refurbishment.”

Hotel Schloss Montabaur

G+K Trockenbau GmbH

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 metre 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.

Judge’s Comment: The result of this very high craftsmanship over the course of 8 months of building works is a truly beautiful building boasting excellent attention to detail.”


The Whitworth Art Gallery

CW Solutions Ltd

Founded in 1889 as the first English gallery in a park, the Whitworth has been transformed by a £15 million development. Part of the University of Manchester, the Whitworth is a gallery that is a place of research and academic collaboration. ISG were the main contractors on this project, while MUMA Ltd was the principal architect. MUMA’s extension to the gallery and refurbishment of the existing 19th century building has sustainability at its heart. The refurbishment and extension of the historic Whitworth Art Gallery incorporated the use of two coat plaster on laths to form vaulted ceilings and curved walls. The scheme was completed over a two year period using over 4000 square metres of two coat plaster, alongside the use of specialised plasters for specific areas. The plastering and dry-lining works were completed over a 14 month period. This represented a real achievement particularly as the original ceiling had to be rebuilt, an unforeseen event in the works programme.

Judge’s Comment: The contractor had to face a very difficult refurbishment of this heritage building, and the excellent craftsmanship and aesthetics of this project really set it apart.” 

Kempinski Hotel

Maxim for Real Estate Investments

Kempinski Hotels is Europe’s oldest luxury hotel group. Kempinski is now launching its second hotel in new Cairo, located 20 minutes southeast of Cairo Airport. Due to the complexity of the interior design regarding shapes and levels that needed to be applied on a triple height ceiling, it required high load bearing. As for wet areaslike the spa, rest rooms and showers, moisture and fire resistance boards were the perfect solution.The advantage of the Gyproc STIL-PRIM suspended ceiling system was that it solved a technical deflection created by a local manufacturer of metal systems which was below the project standards. Gyproc STIL-PRIM suspended ceiling system provided better productivity. This helped the plasterboard contractor to meet the project deadline, which otherwise would have been very hard with the performance of the locally manufactured system.

Judge’s Comment: The great initiative of the drywall contractor in this project led to the proposal and subsequent implementation of a new suspended ceiling system; the result is a magnificent ceiling designed in a triple layered height.”

Raiffeisen Multi-Purpose Center Raaba

Lieb Bau Weiz GmbH & Co KG

Upgrading the Raiffeisen Landesbank Styria to a new Multi- Purpose Center was a huge project. With about 45,000 square metres of gross floor area, it provides modern office workplaces for more than 400 employees since spring 2014. The building also houses the new high-security data processing center as well as a bank branch, a conference and event center and a restaurant. Architectural design played an important role in this project. At the same time, the building owner put a high emphasis on aspects of ecology and sustainability. The use of photovoltaics, the utilization of the data center’s excess heat as well as the cooling system fed by groundwater meant significant savings in operational expenses. In addition, these systems together with the RIGIPS solutions offer a significant contribution to the positive life cycle assessment of the building. The Multi-Purpose Center was awarded the DGNB Blue Building Certificate in Gold.

Judge’s Comment: The good cooperation between the contractor and the Saint-Gobain team resulted in the successful implementation of a tailor-made curved ceiling with mould elements and a specific Q4 finish.”

Ans Public Swimming Area


The public swimming pool in Ans, designed by architect Jean- Michel Ruols is a prime example of technological innovation. Timeless architecture, functionality, beauty and sustainability were the keywords. The exterior is given a streamlined look by large Saint-Gobain glass sections and the curved roof which is shaped like a wave. The well-being of users and the optimisation of maintenance costs were prioritised. The use of Gyproc Aquaroc cement based plasterboards was perfect for the design, as they have a smaller environmental footprint than cement. Gestrab used them as partitions and wall linings in the reception space, changing rooms and swimming pool space. In other projects the robust appearance of the Aquaroc plates is often hidden behind tiles or another finishing layer, but the architect chose to expose it here. It is reminiscent of the look of concrete walls. The interior screw heads were hidden from view by fitting the plates between stainless steel sections.

Judge’s Comment: This project is a prime example of technological innovation. Through an innovative use and application of Aquaroc boards, the contractor succeeded in meeting both high moisture and mould resistance performances and achieving an aesthetic result.”  

St John's College Respond! Housing

Mythen Construction Ltd

This project involved the complete refurbishment of a former seminary by the Respond! Housing Association into 21 self-contained apartments for the elderly. The refurbishment project takes the history of the Gothic Revivalist style building into account, as its aim was to preserve and protect the old walls, fine stain glass windows and beautiful stonework. Gyproc Partition systems incorporating SoundBloc plasterboard were used as the separating compartment walls offering optimum levels of acoustic separation while also meeting the required levels of fire resistance. Gypfloor Silent systems were installed to maintain the required level of impact sound reduction on the compartment floors. This project was a major intervention in a historic building and there were strict guidelines to be met in terms of conservation (and meeting the current building regulations).

Judge’s Comment: This fantastic renovation achieved a very high quality finish and boasts superior aesthetics throughout. This was a very technically challenging project completed to a high standard using the best of the technical solutions Saint-Gobain has to offer.”

Business Academy Aarhus

Arne Danielsen A/S

This building was an addition to Erhvervsakademiet Aarhus/ Business Academy Aarhus. The design of the building and its interior is meant to inspire students to learn in a bright and creative environment centered on an open atrium. It is a great example of a lightweight building solution and one of the first major low-energy houses in Aarhus. The building has 900 square metres of solar panels on the roof and a heat recovery system. The building’s energy use is completely dependent on renewable energy. The project is a great example of a broad use of Gyproc products and systems both externally and internally from thermal insulation to acoustic regulation. One of the most interesting parts of the installation was the façade. The challenge here was finding the right dimensions for the profiles and angles in order to hang the facade as opposed to letting it rest on the plinth. Interestingly, it was also constructed in sections on the ground and then hoisted and put in place.

Judge’s Comment: This building, characterized by sharp details and clean lines, extensively used Saint-Gobain products and systems both internally and externally with Glasroc H and Glasroc F boards but also Rigitone ceilings.
