London Wall Place

CASE STUDY

In the City of London, London Wall Place is a striking addition to the ever-evolving London scene. It comprises of two landmark buildings and an acre of landscaped public realm set amongst the historic monuments of the Roman City Wall and St Alphage Church Tower ruins. The two buildings feature a unique cladding façade which is cantilevered out over London Wall and will provide office space for up to 5000 employees.

Challenges

Build and design contractor Multiplex, identified that these buildings would utilise the roof areas to site some of the mechanical plant required to operate the buildings. This necessarily involved the penetration of the weathering layer as the services and ducts passed from within the building envelope to the roof area. Therefore it was essential to maintain the integrity of the building at these critical points

Solutions

After considering various options, Multiplex selected the ROOFBOX Modular System as their preferred option, due to its flexibility, and the ability to easily add further service penetrations at a later date if required. Nicholson was involved in the project from the early stages and throughout to ensure all requirements were delivered on time. The system comprises three main elements which were installed in the following sequence.

Lastly, the colour matched flashings were fitted to complete the weathering to the services.

The ROOFBOX® weathering system for service penetrations provides a proprietary and guaranteed solution to the inherent problems associated with bringing pipes, cables and ducts through the waterproofing layer at roof level. These insulated aluminium units are powder coated and provide an alternative to the traditional ‘dog kennel’ approach to weathering services as they exit onto the roof.
