A new 217 bedroom 4-star Novotel hotel has been built right next to Cambridge North Station.
The 6-storey building includes a bar and restaurant, as well as a gym, swimming pool, conference facilities and 160 m² of retail space. The new hotel development is the opening scheme to the wider Cambridge North mixed-use regeneration masterplan by Brookgate.
The railway line is only a couple of metres away from the building and the acoustic consultant specified that the building need to be isolated on 7Hz elastomer bearings to protect the hotel rooms from structure-borne noise.
7Hz CDM-SEB bearings were used to support the cores below ground floor level and at the top of every ground floor column.
CDM designed, manufactured and installed failsafes, steel plates and tension details to cope with disproportionate collapse and also shear keys to restrict movement in the stability cores.

Located on the second floor of the new Lillénium shopping center, in Lille, France, this new Basic-Fit club represents a further step in the growth strategy of one of the largest fitness chains in Europe.
Basic-Fit Lillénium is open between 8 a.m. and 10 p.m. and between 9 a.m. and 7 p.m. on weekends. The club offers multiple activities including a GXR room, a virtual spinning room, a functional and lightweight lifting zone, and the typical cardio, power and free-weight zones, all equipped with Matrix fitness equipment. With this wide range, it’s almost impossible not to move. However,
all these activities generate significant amounts of airborne and structural impact noise.
Immediately above and adjacent to the club are several shops, whose opening hours are largely the same as those of Basic-Fit Lillénium.
- CDM-GYM-XP with GYMPACT45 and dBooster®
technology in the free, lightweight and functional areas
High mechanical resistance and acoustical
performance with a lightweight isolated floating
- CDM-GYM-HP in the strength area
Isolated floating floor to reduce the impact noise
generated by the free fall of heavy stacks in
- CDM-GYM-SP in the cardio zone and the GXR room
A stable full-surface floor system able to improve the
acoustics in areas with rhythmic and synchronized
The isolation of the most critical areas with CDM solutions allows gym visitors, shoppers and visitors to coexist without disturbing one another.
GTC White House
Along Váci street, one of the main traffic arteries in Budapest, GTC White House is erected. This state-of-the-art office and retail building designed by the internationally renowned architect Zoltán Tima (KÖZTI – Tima Stúdió) covers over 21.500 m², including the refurbished 100-year-old Schlick Elevator Factory, which is now converted into a 2.000 m² stand-alone loft.
Just a couple of minutes away from two metro stations and tram line No. 1, the chic and airy building complex with its impressive art deco façade and open plan lobby, is one of Budapest finest office locations. Behind the traditional yet contemporary stone and glass façade lies a ‘green’ building that has been awarded the BREEAM and LEED Platinum certifications for its sustainable design and commitment to reducing energy consumption. Besides efficient insulation, thermal insulating plaster, and selective glass with high solar transmittance, GTC White house has a green roof and rainwater recycling system.
In order to guarantee optimal user comfort in a building of this size, a great many HVAC units had to be installed. The 7th floor HVAC area, which is adjusted to the sloping roof slab, is acoustically isolated from the rest of the building using a custom-made CDM-LAT floating floor system.
Due to the weight of the HVAC units and the competitive price on the Hungarian market, and because of the need to effectively reduce the vibrations transmitted into the building structure, a CDM-LAT system using natural rubber pads was proposed.

MEININGER Budapest Great Market Hall
Budget chain MEININGER Hotels recently opened its first hotel in Hungary, the MEININGER Budapest Great Market Hall. The latest addition to the portfolio of this international budget chain thanks its name to its prime location, right next to the Central Market Hall at Fővám tér, close to the Danube.
Together with the MEININGER Hotel design team, Kai Ratschko, owner of the German Ratschko architectural office, created a unique, modern hotel with a distinctive style. The 184 rooms, reception desk, lobby, breakfast area and bar are painting in fun, bright colors and are decorated according to the Hungarian applied arts style, giving the seven-storey hotel a local identity.
According to the ‘hybrid design’ concept, MEININGER Budapest Great Market Hall offers its guests the services and comfort of a budget hotel, with additional extraordinary facilities such as a guest-kitchen and games room.
To guarantee that guests can enjoy a good night’s sleep and a relaxing stay, CDM-PHS acoustic suspension hangers and CDM-CHR metal springs were used to decouple the HVAC units from the rest of the building structure, preventing vibrations and noise from becoming a nuisance.

Cutler Fitness by Allure
In the historic town of Eger, known for its castle, thermal springs and baroque buildings, lies the newly built Cutler Fitness by Allure, a 5.000 m² hotel, sport and wellness center. Here, at the foot of the Bükk mountain range, Alaszka-Bau Kft. constructed a luxury housing and modern sports and recreation center for locals and tourists alike.
The complex comprises four separate units: a 20-bedroom hotel, a fully equipped gym, a luxurious spa and a restaurant that fits the healthy lifestyle promoted. To shield the rest of the hotel and spa of unwanted noise and vibrations coming from the fitness area, a CDM-FLOOR-T acoustic floating floor was installed. This resilient floor batten system capable of supporting both wet and dry floating floors can be anchored to the structural floor, allowing for inclinations. Thanks to the natural rubber isolator pads and the 104 mm air void, on top of which a thick screed floor was installed, the required noise isolation was achieved.
Canal 11 Studio
Canal 11 (Channel 11 in English) is the subscription television channel of the Portuguese Football Federation. Besides covering live soccer matches of Portuguese teams, the sports channel brings programs about beach soccer and the women’s competition. Canal 11 also brings in-depth stories about Portuguese soccer players and live debates.
Constructed south of the new sports pavilion ‘Football City’ (CF – Cidade do Futebol) in a lush green part of Oeiras, Canal 11 studio comprises almost 250 m² of recording studios, office space, etc.
The geometric configuration of white cubic volumes was partly constructed using prefabricated metal modules, with the biggest cube being approximately 13 meters high. Offices and lounges overlook the training pitches in front of the building complex.
To isolate the technical equipment room located directly above the main television studio, a CDM-LAT isolated steel floor batten system was installed beneath the timber floating floor made of double layered calcium-sulfate panels.
The CDM-LAT channel system was custom-engineered to cope with different permanent loads (technical equipment) and achieve a natural frequency of 7 to 9 Hz, preventing unwanted noise and vibrations from reaching the television studio below and interfering with the live broadcasts.

Lux Prime at Benfica Stadium
Lux Prime is a new housing concept offering a distinctive lifestyle and environment, harmoniously blending the architectural line of the building with its surroundings.
Facing the Sport Lisboa e Benfica Stadium (Estádio da Luz), Lux Prime condominium offers the best of modern-day living. The spacious apartments with terraces and balconies are all equipped with high-range appliances and luxurious finishes. Rooftop leisure spaces, including a 30-meter-long infinity pool, deck, and outdoor gym, offer stunning panoramic views of Monsanto Park and the rest of the city.
People swimming and jumping into indoor and outdoor rooftop swimming pools generate structure-borne noise which, if left untreated, will become a nuisance in neighboring spaces.
To guarantee maximum comfort in the duplex apartments below, a CDM-POOL acoustic isolation solution was installed underneath the rooftop pool, decoupling the pool and pool deck from the supporting structure, resulting in high levels of isolation.
Fitness Park Tours
With more than 30 years of experience, 700 000 clients and over 220 clubs, Fitness Park is one of the largest gym chains in France. The high-end fitness chain is planning to open another 70 clubs this year alone.
In the summer of 2020 Fitness Park opened its latest club in the L’Heure Tranquille shopping center in Tours. With a surface area of 1100 m², Fitness Park Tours is one of the larger gyms, with plenty of room for various gym activities such as weightlifting, spinning, group classes, but also more intensive workouts like boxing and cross-training.
With a promise to deliver their clients the best gym equipment and the best fitness experience out there, Fitness Park called in CDM to address the flooring and isolate unwanted noise and vibrations at their latest gym in Tours. Due the type of activities and to ensure a peaceful environment in the neighboring stores, a customized CDM-GYM-HP system with GYMPACT25 and dBooster® technology was installed in the area where medium-high impacts are expected (with impact energy levels of up to 600 N.m).
This discrete solution is performance-engineered to control vibrations, minimize low-frequency impact noise, and reduce the transmission of structure-borne noise. Using the patented dBooster® technology, the floor system’s performance is independent of the impact energy level applied to the system.
As a final floor, Fitness Park was able to install their standard floor covering, ErgoFloor Rubber Tiles.
Fitness enthusiasts are now able to exercise to their heart’s content without having to worry that their activities are disturbing the neighbors.
Adare Manor Hotel & Golf Resort
Amidst an 840-acre estate consisting of sweeping parklands, masterfully designed French gardens, and a magnificently maintained championship golf course, stands Adare Manor. The 19th century romantic Neo-Gothic gem that is Adare Manor was once the family home of Windham Henry Quin, the 2nd Earl of Dunraven and his wife, Lady Caroline Wyndham.
Modelled after the great European chateaux and cathedrals, this stately home is a tribute to the Dunravens’ sense of exuberance, wit, and style. The building displays a wealth of gargoyles, heraldry and decorative stone and wood carvings. The interior spaces are designed on a grand scale, with the most renowned space being The Gallery, a 132-foot long, 26 ½ foot high expanse inspired by the Hall of Mirrors in Versailles.
Today Adare Manor is an exclusive 5-star hotel that offers its guests an unforgettable stay. The historic manor house has been transformed with great attention to detail, making it the perfect retreat for anyone wishing to immerse himself in history and luxury.
Our local branch CDM Ireland was tasked by RSK Acoustic Consultants with providing a gym floating floor solution for the gym at the new Adare Manor Guest Facility. In order to reduce impact noise from the gym, causing nuisance in the spa area below, RSK Group set the acoustic criteria at NR 30 for the wellness area.
To meet the required noise rating level CDM designed, supplied and installed a CDM-GYM-XP acoustic floating floor with a GYMPACT20 absorption layer and a 10 mm Sports Floor covering for the free weight area. In the rest of the gym, including the ballet studio, a CDM-GYM-XP without GYMPACT20 was installed below the oak timber floor covering. With the new acoustic floating floors in place, hotel guests can be assured of a relaxing stay at Adare Manor.
Basic-Fit Villa de Vallecas
Basic-Fit Villa de Vallecas is one of the more than 800 clubs that Basic-Fit, one of Europe’s largest fitness operators, has in Spain, Benelux and France.
Even with Basic-Fit speeding up their expansion plans for the European market, it doesn’t ignore the well-being of their existing customers and fitness centers. Various Basic-Fit locations all over Europe are being transformed to improve both aesthetics and user comfort. One of those locations is Basic-Fit Villa de Vallecas, located on the first floor of the “Mercado Villa de Vallecas” building, in Madrid.
Basic-Fit decided to address the floors as well, to respond to the noise complaints of the neighbors. After an initial analysis, it soon became clear that the free-weight zone was the main source of noise.
With only 2.6 m of available space between the existing floor covering and the ceiling and, according to the standard layout of Basic-Fit clubs, 2.4 m high cable crossing machines installed in the free-weight zone, the height of the acoustic floor system was limited to a maximum of 125 mm.
Keeping the standard gym lightweight floating floor setup, CDM designed a custom CDM-GYM-HP with GYMPACT35 dry floor system, able to reduce the noise generated to acceptable levels and adding only limited extra height, as desired by the client.
In order to verify the performance of the system, a mock-up was first installed on which weights were dropped from different heights. LAF,MAX values were measured that not only comply with the legal limits, but also meet the requirements with regard to the noise complaints of the neighbors.
Fitness enthusiasts are now able to exercise to their heart’s content without having to worry that their activities are disturbing the neighbors. The intervention was quick, easy and clean, allowing Basic-Fit Villa de Vallecas to keep the other zones in the gym open, even during installation. The free-weight area was able to reopen after only a couple of days. The installed floating floors did not add too much weight or height and the client was able to reuse his rubber tiles as final floor covering.
