GHA are delighted that their London City Island and Wardian London projects have featured in New London Architecture’s latest research paper on factory-made housing. NLA have been investigating the role of factory methods in delivering the housing London needs and have produced a publication, exhibition and programme of events which will be taking place from October to December.
At London City Island, residential buildings are constructed using prefabricated concrete structural panels which gives an agile method of working that delivers a high-quality finish with robustness, speed and safety of construction. External walls are formed using a system of prefabricated, brick faced cavity wall panels with a full brick outer leaf and loadbearing RC inner leaf. Windows are pre-installed off-site, along with thermally broken stub connections to receive external balconies. This approach has a significant benefit on the project, particularly by much-accelerating delivery as floors can be complete (including glazing) on a seven-day cycle. Panels are installed from crawler cranes. Build quality is excellent with multiple package interfaces are incorporated into a single system.
Wardian uses factory-made balcony, facade modules and bathroom pods which are shipped to site and installed with minimal adjustments. Facade elements have been designed to allow the facade and balcony installation independent of the tower crane. A high level of detail and precision was achieved by using factory conditions for all assembly and manufacturing processes. BIM and 3D modelling were used to test the pre-fabricated elements for easy on-site manoeuvrability, which additionally improved construction safety given the limited operations and activities on site. Due to the projects’ high level of pre-fabrication, the speed of installation and build quality have been enhanced and costs optimised.
Studio Director David Henderson said “The NLA are to be commended for the publication, exhibition and programme of events. We are delighted that two of our projects were featured.”
The paper was launched at an event featuring the Rt Hon James Brokenshire MP, Secretary of State for Housing, Communities, and Local Government, and Richard Rogers, Founding Partner, Rogers Stirk Harbour + Partners.
