PSE were appointed to provide structural design services for a single storey rooftop extension to an existing block of residential units.
Construction comprised of a suspended steel grillage supporting pre-fabricated light-weight timber frame panels.
The proposed residential units were located above an existing four storey reinforced concrete frame comprising of retail space and residential units.
The project presented the challenge of appraising the existing structure for the additional load from the proposed rooftop extension. The PSE team overcame this by a combination of structural surveys, diligent desk study and finite element modelling of the existing structure.
