141 Fifth Avenue (Merchants Bank Building)

The facade reads in three registers: the Maynicke mid-block bays of limestone and terra cotta to the south, Ficken's curved corner with its banded columns and round windows, and the copper dome above. Within the Ladies' Mile Historic District, all of it is protected — exterior alterations require Landmarks approval.

The 38 residences of the conversion (34 units in current city records, reflecting combinations) run from one-bedrooms through three-bedroom lines of loft-scaled proportions — high ceilings, oversized windows, and the deep floor plates of a commercial building — capped by four penthouses, including the cupola triplex. Storage transferred separately at conversion via 40 storage-bin license agreements per the offering plan. Finishes date to the 2007–2009 conversion, and current condition should be assessed apartment by apartment when comparing prices.

A boutique full-service condominium: doorman, concierge, live-in superintendent, fitness center, common roof deck with open city views, package room, and basement storage. There is no pool or parking; recent listings document common charges around $3,000–3,200 monthly on mid-size lines, but the 38-unit count and amenity mix alone do not establish comparatively low charges. Confirm the current apartment-specific charges, assessments and budget. The commercial base is separately owned, so residential owners should review the condominium's cost-sharing structure with counsel during diligence. The offering plan, amendments, and by-laws are on file in The Roebling Research Library.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,940/sf (floor-adjusted) across 2 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 5.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00849-7505; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

You are buying the facade as much as the floor plan. The dome, the curved corner, the restored balcony — these are historic-district-protected assets that no competing building in the corridor can replicate. Use dated, adjusted sales of conversions and newer towers to assess price; architectural distinctions alone do not establish a premium.

Understand the commercial base. The lower floors were retained for commercial use under separate ownership at conversion. Your attorney should review how the condominium documents allocate costs, building systems, and lobby/entrance control between the residential and commercial components.

Line selection is a light-and-view exercise. Corner lines take the Fifth Avenue and 21st Street exposures; mid-block lines face south over lower Ladies' Mile fabric. The two added floors and penthouse tier carry the open-sky premium. Same-line history matters more than building averages.

Mansion tax applies essentially everywhere in the building. Run the Mansion Tax Calculator at the intended price point — most of the building's trades clear multiple threshold bands.

Verify the fee stack and rental terms. Transfer-fee, sublet, and structure policies are thinly documented publicly. We verify against the offering plan and by-laws on file, and current managing-agent requirements, during diligence.

Lead with the building's documented history. Maynicke, 1897, the Merchant's Bank, Ficken's dome, the CetraRuddy restoration — these are specific architectural and conversion details to document for prospective buyers. We market from the primary record, including the offering plan on file.

Position against the new-construction towers deliberately. Compare 45 East 22nd and One Madison with the protected Beaux-Arts architecture and 38-residence conversion plan here. Show dated prices using consistent area measures, together with each building’s services and total carrying costs.

Condition now differentiates. Conversion-era finishes are approaching twenty years old; compare renovated and original-condition sales with adjustments for scope, floor, exposure and sale date. Run the Renovation Cost Calculator against your asking strategy before defaulting to as-is pricing.
