Calispo rooftop extension – Lugano (SV)

Eco‑repositioning of a traditional building: extension and rooftop addition with IBS and Platform‑Frame systems

The “Calispo” project converts a 1960s hotel into modern flats by enlarging each existing floor and adding two new timber levels. The solution lowers structural loads, speeds up construction and boosts energy performance.

Main details:

• Type: multi‑storey building – extension + rooftop addition
• Areas: extension 120 m² on each of 7 floors; rooftop (8th‑9th) 1,010 m²
• Building systems: IBS for extension, Platform‑Frame for rooftop levels
• Usable flat roof designed as a terrace (capacity 850 kg/m²)
• Record assembly: 3 weeks for extension, 5 weeks for rooftop
• Minimal intervention on the original structure to cut time and costs

This timber rooftop extension shows how prefabrication enables rapid, sustainable upgrades without new land consumption.
