Description
Iron Lofts is Flatiron’s newest boutique development with just 6 full-floor, classic condominium lofts in the neo-industrial heart of the Ladies’ Mile Historic District. Fully renovated and carved from a landmarked 1909 Renaissance Revival apparel building, this new portfolio of statement homes warmly embraces its history, punctuated by Scandinavian design principles of simplicity, function and textural blends. 2082 square feet of architectural perfection begin with a private key-lock elevator that leads to the gracious entry foyer and onward to a grandly-proportioned living area. Wide-planked floors of smoked oak stretch to oversized south-facing windows and continue paneling the walls beneath adjustable recessed cove lighting. An open kitchen offers top-of-the-line appliances from Miele and Sub-Zero and are tastefully incorporated into locally-milled cabinetry. Spacious bedrooms including a lavish primary suite, each include serene en-suite baths and generous closet space outfitted with custom millwork. A third full bathroom accommodates guests, attired in penny tile, granite, and glass. Additionally, a perfectly proportioned home office, den or media suite offers separation and privacy. All homes include private laundry rooms with sink and linen storage. Central air conditioning. Oversized new windows. 24-hour remote monitoring and secure package delivery is coordinated via virtual lobby attendant, offering convenience and security with the utmost of discretion. Moments from Fifth Avenue shopping, transit, and Madison Square Park. A special and rare offering of timeless elegance. The Complete Offering Terms are available in an offering plan available from Sponsor. File no. CD-210292. Equal Housing Opportunity.
