When building the luxury residential complex, materials of the best quality should be used, which guarantee durability and safety in the installation.

aquatherm products were selected to minimize the risk of leaks and to guarantee smooth operation for decades.


  • Thanks to the special material properties of the material polypropylene, corrosion cannot develop either inside or outside the pipe
  • As a result, the systems are extremely durable and work in an energy-saving manner even after decades
  • Polypropylene prevents microbiological growth in drinking water, which provides a breeding ground for germs and bacteria

Kensington is a special place to live. In the immediate vicinity of the famous Kensington Palace and the Royal Albert Hall, the district is considered to be the aristocratic district of London. The well-tended living area with its buildings and facades from the Victorian era includes numerous luxury objects, including the newly built apartment complex “21 Young Street” (, which was built to be of the highest quality.

The demolition of a former, multi-storey car park from the 1960s at 21 Young Street provided the owner, British residential real estate company Grainger plc, with the rare opportunity to construct a new building on the edge of one of London’s oldest squares. The complex was to adapt to the listed residential buildings around Kensington Square. The architects at Assael Architecture Ltd were inspired by the traditional mansions of Kensington Court and created an elegant brick building that extends from five to eight floors along Young Street.

A total of 53 luxurious apartments and penthouses have been created on around 80,000 square meters, which are supplemented by a fitness studio, library and private cinema. Only the highest quality materials were used, such as Carrara marble in the bathrooms, special woods and exquisite Fortuny fabrics. In collaboration with the jewelry designer Shaun Leane, who is best known for his sculptures designed for the fashion designer Alexander McQueen, filigree metal work was created on the balustrades and gates: bronze leaves that seem to blow in the wind. Another special feature is the inner courtyard, which can be used for relaxation or business meetings. An underground car park completes the facility.



The building technology should also meet the highest demands of the client. The specialist planners at Hoare Lea originally planned systems made of steel and copper for the piping. Following a recommendation from the installation company Greenside Integrated Services Limited, who had had very good experiences with aquatherm systems in an earlier project, the decision was made to use aquatherm products made of the high-quality plastic polypropylene instead of copper and steel. The installers were particularly impressed by the connection technology learned in a training course offered by aquatherm: In “fusion welding”, the pipe and fitting are briefly heated and then joined. As a result, the plastic melts into a homogeneous, cohesive unit and is extremely stable at the connection point, which is critical in other systems. This minimizes the risk of leaks, which can lead to expensive renovations. Fast assembly is guaranteed.

Thanks to the special material properties of the material polypropylene, corrosion cannot develop either inside or outside the pipe. As a result, the systems are extremely durable and work in an energy-saving manner even after decades, as the water flow is not impaired by deposits.


A total of around 25,000 meters of aquatherm pipelines with dimensions of 20 to 125 mm were laid from the technical room to the apartments. The aquatherm green pipe was installed in order to transport drinking water in a hygienically perfect quality for decades. In contrast to metal piping systems, which can release heavy metals that are problematic for health into the drinking water over their service life, the drinking water quality is permanently maintained with this odorless and tasteless piping system. Thanks to its special material properties, the material polypropylene prevents microbiological growth, which provides a breeding ground for germs and bacteria.

aquatherm blue pipe was installed for the heating, cooling and condenser pipes. The physical properties of the plastic are tailored to the special needs of the heating and cooling sector. It is characterized by its high temperature and pressure resistance. A special service ensured quick installation: thanks to prefabricated distributors, which were already installed in the aquatherm factory and then delivered to the construction site ready for installation, the Greenside installers saved a lot of time.
