Peregrine Deck is a rooftop settlement spanning seventeen contiguous building crowns in the Old Harbor mid-tier zone, connected by a web of tensioned cable bridges, pressurized tube corridors, and open-air market platforms bolted to former HVAC infrastructure. It began as a squatter encampment when a Palladian Group development stalled mid-construction forty years ago, leaving three rooftops capped with unfinished structural plating. Enterprising residents welded the gaps, and the settlement grew outward one rooftop at a time until it became something too large and too useful to evict.

The Deck operates at approximately forty stories above street level, above most of the smog band, and benefits from genuine lake wind and unfiltered daylight — luxuries that make it more desirable than its Tier 3 paperwork would suggest. A thriving informal economy has grown around this: rooftop cafes with actual views, solar-capture cooperatives, and a well-regarded open-air clinic run by a Helix Biosystems-trained surgeon who left the corporate track under circumstances she declines to specify. The Palladian Group has never formally abandoned its development claim on the underlying structures, which means Peregrine Deck exists in perpetual legal limbo — one board vote away from demolition, and aware of it.
