We are a specialist rooftop development company that turn under utilised rooftop spaces into valuable assets with minimal disruption to existing occupiers. Modular construction is a process in which a building is constructed to various degrees off-site. Under controlled conditions, using the same materials and designing to the same codes and standards as traditional construction – but in approximately half the time. With advanced modular construction First Penthouse takes this a step further by doing close to 100% in the factory, including testing of all the installations before the modules leave the facility. In essence this is greener, quicker and enables greater quality control. But the main benefit compared to traditional construction is the minimal disturbance to existing occupiers. On-site works are undertaken methodically and quietly to minimise disturbance.
