Potential / Hypothetical Context for ‘Round Tower’ Landmark Building : Lower Manhattan, New York

Round Tower Tall Building Proposal : Architectural Design Statement & Symbolism

An Iconic and instantly recognisable Signature Landmark with very strong Brand Potentiality
Proposal is intended to be Symbolic of Irish Contribution to the United States of America
As of 2025 , Almost 35 Million or 1 in 10 Americans claim to be of Irish Descent / Heritage
A Contemporary Interpretation of Ancient Irish Architecture with Deep Cultural Resonance
A Unique addition to New York’s World Renowned Skyline and Architectural Identity / Ensemble
Building Form reflects that of Medieval Round Tower. Composition based on rule of Thirds
Stone Elements to Base respects Ancient Tower Construction & Creates interest at Street Level
Contemporary Steel and Concrete Superstructure using Steel Diagrid or RC Supercolumns.
Apex as per Historical Round Tower Form with Glazing for Jewel / Beacon effect & Views over City
Plan Shape can be Circular, Elliptical, Oval or Octagonal without compromising Architectural Ethos
Ideally situated within a Waterfront setting although Apex allows for Prominence if located in Urban Core
Potential for Public / Commercial Recreational space at Apex Levels ( Lounge Bar / Restaurant etc )
Likely Diameter to be circa 45-50meters. Therefore desirable Slenderness Ratio guides total height .
Apex Angle heavily influences Ideal Aesthetic. Must be ~ 65 degrees for Aesthetic appeal.

Development Finance / Capital Stack Subdivision

Common Equity : Originator Equity | Fee / Early Investor Team / Irish Plcs / Irish Funds (5-10%) ?

Preferred Equity : Sovereign Wealth Fund / Pension Fund(s) / Foundation / Endowment / Individuals / Families

Mezzanine Finance : US Plcs / Irish Plcs / Real Estate Fund(s)+ Life Insurance Company(s) + HNW Individuals

Senior Debt (Commercial Bank) Financing : less than 75% due to Iconic Potential of Proposed Development ? Possible to raise Larger Share of Construction Cost via Equity rather than via Debt due to Iconic Potential of Proposed Development – ie. Signature Building & Associated Branding Potential / Symbol of Irish America

Brief Development Description

Main Central Section & Structural System : If Steel Tube Diagrid , then likely to be 4-6 Storey Triangular Sections subject to individual Steel Tube assembly and sizing , connected via Pre Cambered Steel Nodes with radial Steel Beams at each Floor Level connecting to Steel Columns within R.C. Core. Circular Plan Shape contributes to Wind Load reduction. Floor to Floor circa 4.0 metres. Belt Truss Floors with Steel Bracing to form Perimeter Outriggers – spanning 2 Floor levels in height at Intervals to be determined by detailed design development. Belt Truss Levels to be possible location for MEP Floors and Elevator / Sky Lobby’s subject to Vertical Transport programme. Alternatively, Investigate removal of Floor Space at Belt Truss Locations to allow for a series of ‘Notches’ to Building Profile for further alleviation of Wind Loads and for potential SkyDeck or Skygarden spaces.

Alternatively, in lieu of Steel Diagrid System to Building Envelope, consider 4 Vertical RC + Steel Cores with Built in RC. Super Columns ( Outer Wall & inner RC Core) at 90 degree Orientations to give Cruciform shape in Plan with Smaller central Core reserved for Dedicated Vertical Transport to Apex of the Building. Likely Floor system to be poured R.C. Concrete Slab on Profiled Metal Decking System with Raised access Floor. May allow for Interesting Vertical Circulation possibilities compared to conventional Core.

Alternatively, in lieu of Steel Diagrid System, consider Mega Frame Structure with CFST Columns or ‘Super Columns’ of preferred internal Steel configuration, with Belt Trusses and Multi Storey Bracing, Fixed to RC. Core.

Building Base : Where Steel Diagrid System meets Ground Level a series of Stone Infill Structures will be Constructed to sit either Flush and Expressed Externally within the Steel Diagrid System in lieu of Glazed Sections , or Alternatively to sit within and just behind the Steel Diagrid Frame and behind the Glazing System so that the Glazing System sits forward of the Stone walls. These Stone Wall Structures would be Random Coarsed Rubble within a secondary R.C. Or Steel frame and would reference the Ancient Masonry Construction of the Irish Round Tower. They would be uplit and have Stone Panels with Artistic Reliefs or Engravings depicting Themes from Irish History. Openings would be formed within these Stone Structures for Access and Egress to the Concourse / Lobby Areas. Wintergarden Spaces to Ground Floor Lobby Areas with Commercial Space for Cafe / Dining.

Building Apex : Cone shaped Diagrid comprising Triangular Sections each spanning 2 Floor Levels to Form Building Apex / Roof Area. Robotic Rotating Building Cleaning System at Junction of Coned Roof to Main Building Structure. Rooftop Lounge Bar / Dining Area subject to Vertical Circulation Programme. Damper provision subject to Structural Engineers recommendations.
