The Oriana

Project Overview

Renovating a building while it lived in itself

The Oriana is a 38-story luxury residential tower in Sutton Place, one of Manhattan's most prestigious neighborhoods. rcRussell was engaged by Slate Property Group, working alongside Gachot Studios as design architect, to deliver a full-building transformation: a vertical structural expansion paired with a complete unit-by-unit restack of all 411 apartments, executed inside an actively occupied building.

The vertical expansion added new structural steel atop the existing tower, converting the original roof into a full residential amenity floor — the rooftop terrace and indoor amenities visible across the gallery.

At the cellar level, rcRussell also delivered a full new amenity build-out — children's playroom, vintage arcade, dog wash, party room, climbing wall, and a private outdoor courtyard — extending the building's residential program below grade while the floors above remained occupied.

The work required the kind of operational discipline that doesn't tolerate improvisation. Residents continued to live in the building. Concierge and amenity services continued to run. Life-safety systems remained certified and online. Every floor was a live operational environment with its own constraints, schedules, and sensitivities.

What rcRussell delivered was not just construction — it was the coordinated choreography of construction inside a functioning luxury residential community.

Executing a 411-unit restack and structural expansion inside a fully occupied high-rise demands a level of planning that begins long before the first wall comes down. Every floor presented its own operational environment, and every decision had to account for residents, staff, and life-safety continuity.

The Challenge

The complexity of occupied luxury

Working inside a fully occupied 38-story residential tower compounds every constraint in construction. Phased unit turnovers had to be sequenced with resident relocation schedules and lease cycles. Structural steel expansion had to be coordinated above floors where families were eating dinner. Life-safety systems — fire alarm, sprinkler, egress — had to remain certified throughout, never offline, never compromised.

Add to that the standards of Sutton Place: high-end finishes, white-glove resident expectations, and a building where the day-to-day operations of a luxury residence cannot be interrupted. Certificate-of-occupancy boundaries had to be maintained at every phase to keep residents in their homes while construction advanced floor by floor.

Our Approach

Discipline, applied floor by floor

Phased Unit Turnovers

A sequenced restack schedule coordinated with building management and resident relocations, allowing work to progress continuously while maintaining occupancy across all floors. Every turnover treated as its own micro-project with its own punch list and quality controls.

Life-Safety Continuity

Fire alarm, sprinkler, and egress systems maintained or temporarily reconfigured to remain code-compliant at every stage. Detailed coordination with NYC DOB and FDNY ensured that no resident was ever exposed to a degraded safety system during construction.

Vertical Expansion Coordination

Structural steel addition delivered while the residential floors below remained occupied. Vibration, noise, and dust controls coordinated with the building's daily routines. Hoisting and material logistics planned around resident, staff, and amenity-level activity.

Amenity-Space Renovation

Lobby, fitness, lounge, and rooftop amenity spaces renovated in coordinated phases. Temporary substitute amenities maintained where possible so that the resident experience of luxury living was never paused, only shifted.
