Airspace development presents an exciting opportunity to create additional homes, but building upwards comes with unique challenges that need to be considered from the outset.
Before starting your next rooftop development, here are five key questions worth asking:
1.Can the existing structure support the proposed development?
Evaluations of the building’s foundations, frame and roof can identify problems and determine suitability.
2.How can we minimise additional structural weight?
Reducing the load placed on the existing building is central to the viability of an airspace project.
3.Have potential design clashes been identified early?
Detailed design and 3D BIM coordination can help identify interface issues before they become problems on site.
4.How will the project affect existing residents?
Working above an occupied building requires a carefully planned approach to minimise disruptions to occupants.
5.Why work with LGS Modular Expansion?
Off-site fabrication and LGS framing offers increased precision, efficient installation and reduced time spent on site.
At Nexus Modular, we understand that every rooftop development comes with its own challenges. Getting the right expertise and construction strategy involved early can make a real difference.
