KEY BUILDING FACTS Year Built 1915 (converted 2014) Number of Units 125 Developer Witkoff & New Valley LLC Architect Alan Wanzenberg (interiors), Goldstein Hill & West (conversion) Management Company Douglas Elliman Property Management Front Desk Number TBD FINANCIAL SUMMARY Monthly Common Charges / HOA Varies by unit (~$2,500-$12,000) Monthly Taxes Varies by unit (~$2,000-$10,000) Special Assessments None publicly listed Tax Abatement None publicly listed Undivided's Assessment 10 Madison Square West is among the few Flatiron condos that satisfy both halves of the investment equation: a building of genuine architectural character and a balance sheet that holds up under scrutiny. The 1915 Beaux-Arts conversion offers the irreplaceable fabric of pre-war construction, high ceilings, deep setbacks, and thick walls, within a fully modernized residential plant. The common charges are competitive for a building of this amenity depth, which reflects a well-run HOA. No structural or systems issues have surfaced in over a decade of residential use. For buyers evaluating Flatiron condos with an investment lens, this building consistently clears the bar: competitive price per square foot, proven resale demand, and a location directly fronting Madison Square Park that continues to attract a deep and diverse buyer pool. One honest note: the new development premium from the 2014 to 2015 launch has normalized. Trophy units on high floors with direct park frontage continue to command strong pricing and rental returns. Mid-tier floors are more likely to track neighborhood averages going forward. Buy the right unit and the thesis holds. Undivided Value Index™ Score OVERALL SCORE: [View our full methodology ›](https://www.undividedre.com/value-index) 10 Madison Square West A (91/100) Character Profile Investment-grade Beaux-Arts conversion with a sophisticated, design-conscious resident community. SCORE BREAKDOWN BY CRITERION: Location Power 20% \[95/100\] Steps from Madison Square Park, world-class restaurants and multiple subway lines Amenity ROI 15% \[91/100\] 10,000 sf residents club with 60-ft lap pool, full spa, yoga studio, and fitness center managed by The Wright Fit. One of the few buildings where residents actually use what they pay for, and the common charges justify it. Financial Fundamentals 20% \[82/100\] Common charges are competitive and well-managed for this quality tier. Taxes are in line with the neighborhood. The new development premium from 2014 to 2015 has normalized. Prices remain strong but buyers should expect stabilization toward neighborhood averages rather than outperformance. Build & Systems Quality 15% \[94/100\] High-quality conversion, fully modernized systems, classic restoration. No structural or maintenance issues on public record after a decade of residential use. Sustainability & Wellness 10% \[72/100\] Building-wide air filtration and updated mechanical systems. One honest caveat: 1107 Broadway holds a Local Law 33 energy grade of "D" (score 48), which is below average for the asset class. The adaptive reuse of a 1915 structure creates inherent efficiency challenges, but buyers should factor this into long-term carrying cost projections and monitor future compliance costs under Local Law 97. Appreciation Upside 10% \[80/100\] Park-facing and corner-exposure units retain genuine scarcity value. Standard and lower-floor units are likely to track the neighborhood average. Long-term holders of trophy units are better positioned than those expecting short-term appreciation across all floor tiers. Rental & Exit Liquidity 5% \[90/100\] Strong resale history, diverse buyer pool including international buyers. NoMad rental inventory remains tight, supporting strong returns on well-positioned units. Lifestyle Fit 5% \[91/100\] Pet-friendly, flexible layouts, luxury services. Central location at the intersection of NoMad, Flatiron, Chelsea, and Union Square. Works as a primary residence, pied-a-terre, or investment unit. View Value Breakdown What Makes This Building Worth Owning Adaptive Reuse & Systems Quality - A conversion of the former International Toy Center: the original masonry shell and structure preserved, with all mechanical systems fully modernized to current standards. - Updated HVAC, energy-efficient appliances, and building-wide air filtration, infrastructure that reduces long-term carrying costs. Layout Advantage - Generously scaled floorplans, a legacy of the building's commercial origins, that are meaningfully larger than typical new construction at comparable price points. - Select residences include private terraces with park or skyline exposures, a rare premium in this price tier. Design Integrity - Alan Wanzenberg interiors defined by natural stone, warm wood tones, and proportional restraint, a design language that holds its appeal and its value. Investment Case - Consistently strong demand from finance, technology, and consulting professionals, a buyer profile that supports price stability and rapid liquidity in any market environment. Amenity Depth - 10,000 sq. ft. amenity floor: 60-ft lap pool, full spa, yoga studio, residents' lounge, children's playroom, and 24-hour concierge. An amenity package that competes with buildings priced significantly higher. {"highlight\_items":\[{"item\_description":"\
