White Water Quarry in the City of London
Fascinating: 30 metres long, 8 metres high - part of the Lasa (Laas) White Water Marble Quarry in London in the lobby of the new 100 Bishopsgate Tower
When visitors enter the large reception and lobby area of the 40-storey main building of the "100 Bishopsgate" building construction project, newly constructed between 2016 and 2019 on the eastern edge of the financial district of the City of London, they encounter the entrance lobby with 8m high and 30m long walls of refined Lasa marble. The installed wall cladding with Lasa marble of the protected variety group, LASA VENATO®™ is the result of an interesting and unusual process. The architects and designers of Allies and Morrison were fascinated by a local glimpse of the Lasa White Water Quarry (Weißwasserbruch) and decided to design the reception area as if it had been cut out of a single block of Lasa marble. The visitor enters the building and finds himself in front of a huge marble wall of the White Water Quarry, faithfully installed in its original size.
Lasa Marmo has meticulously carried out its own project and planning work to meet the challenges of the London architecture and urban planning office. Together with the partners Euromarble and Szerelmey, this project consisting of 1,300m² of Lasa marble was realised between 2017 and 2019. A special aspect was that the smoke-grey vein pattern characteristics of LASA VENATO®™ had to run diagonally at an angle of 30 degrees across the rear wall and horizontally along the side walls. To achieve this, each block of marble was specially selected. In the innovative "Digital Dry Lay" process offered by Lasa Marmo to architects and designers - for the 100 Bishopsgate project together with its partner Euromarble - marble slabs are first scanned individually at the Lasa Marmo factory using a high-performance scanner, then cut digitally on the computer and, as a final step, assembled like a puzzle and, as in the case of "100 Bishopsgate", into a lobby wall. The big challenge in this project was to get tens of clean transitions of different large and small veins first on the computer and then in the laying. As an additional measure all walls were laid using the classic "Dry Lay" method. In view of the dimension of the walls was used a drone for the first time to fly along the dry laid marble slabs and thus subject every piece to meticulous control.
Lasa Marmo offers interested customers both processes: the "Digital Dry Lay" and the "Dry Lay". With these innovative processes, architects and designers no longer have to be on site in the marble factory, but can select the material virtually and conveniently on their computers, thus saving time and money. This is another answer from Lasa Marmo in relation to specialisation and digitalization.
The selected large-format wall panels for the "100 Bishopsgate" project were cut to a thickness of 3cm and provided with various surfaces. The largest part was sand-waterjet treated and brushed afterwards, which creates a haptic and optical eggshell characteristic. In order not to disturb the continuous vein and the optics of the large wall, even the doors were covered with marble plates in the so-called "Honeycomb procedure". This weight-saving feature is achieved by sticking thin marble plates on a honeycomb plate. The result in the large reception and lobby area of the main tower at 100 Bishopsgate is impressive.
100 Bishopsgate is a recently completed development in London's financial district, which is mainly an office building but also houses restaurants, bars and retail outlets. The project is divided into two buildings. A 37-storey high-rise with a floor area of 4,100m² each on 5 floors as well as 32 further office floors with areas of between 1,800 to 2,300m². The second building comprises 7 floors behind a preserved historical façade and will accommodate restaurant and office floors of 740m² each.
