1 Main Street (The Clock Tower)

The building is a textbook reinforced-concrete daylight factory dressed in Industrial Neoclassical clothing: an exposed structural grid, deep multi-pane window bays between concrete piers, and a classicizing crown culminating in the clock tower. Because the structure is concrete-frame rather than load-bearing masonry, the conversion produced lofts with the attributes the authentic-loft market prices most aggressively — long window runs, high ceilings, concrete ceilings and mushroom-capped columns in many units, and floor plates deep enough for true loft proportions.

The 124 residential units run from compact one-bedroom lofts through full-floor spreads. Typical floors (2 through 12) carry roughly eight lines around the central core; second-floor units in the original schedule ranged from approximately 600 to 2,600 square feet, and the B, C, and D lines face Plymouth Street and the Manhattan Bridge/Midtown panorama while the easterly D-through-H lines historically carried East River exposures. The 1998 plan flagged candidly that future development could affect certain view corridors — a disclosure borne out as the neighborhood built out, and a reminder that view diligence at DUMBO buildings is line-specific and floor-specific.

The penthouse tier — the former Units 14, 15, and 16, each approximately 3,208 square feet before combination — was delivered raw, and the resulting build-outs are one-of-one. The triplex assembled behind the clockfaces, with ceiling heights reported from 15 to as much as 50 feet in the clock room and its three-story glass elevator, is the singular expression of the type.

The ground floor carries the two commercial units — the corner space at Main and Plymouth was configured at conversion around a large restaurant installation — with entrances separate from the residential lobby.

The Clock Tower operates as a full-service condominium: 24-hour concierge station regulating the lobby, non-resident superintendent with a first-floor office, three residential passenger elevators, common roof deck, and the 13th-floor exercise room/health club whose costs are borne by the residential unit owners. Electricity is sub-metered to units. Two Trees Management Co. was the selling and managing agent at conversion; current management should be confirmed with the board during diligence — The Roebling Team remains the contact of record for clients.

One operational feature is genuinely unusual and worth understanding before contract: the building shares base-building mechanical equipment — heating, water, electric, and sprinkler — with the adjoining former Gair building at 30 Washington Street through the powerhouse on the building's south side, under recorded easements that apportion maintenance costs between the two buildings. This is a stable, long-recorded arrangement, but buyers' attorneys should review the easement framework as part of standard diligence.

The original tax schedule was built around J-51 benefits obtained in connection with the rehabilitation; those benefits have long since run their course, and current taxes on any unit should be modeled at full assessment.

Resale and leasing: Sales and leases of units are subject to the condominium board's right of first refusal — the board may acquire or lease the unit, or produce a third party to do so, on matching terms. In practice this is the standard permissive condominium framework: no co-op-style board approval, condominium-fast closings.

Working capital contribution: Purchasers at closing contribute an amount equal to two months' common charges to the condominium's working capital fund per the offering plan.

Flip tax / transfer fee: No transfer fee is documented in the offering plan.

Ownership structures: Individuals, LLCs, partnerships, trusts, and other legal entities may hold title (standard New York condominium framework); pied-à-terre and investor use are permitted subject to the right of first refusal.

Pets and house rules: Governed by the condominium's house rules, which The Roebling Research Library maintains and shares with clients during diligence.

Recent closings at this building, curated by The Roebling Team research desk. 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) cleared a median $1,404/sf across 4 sales. Median listing discount 3.6% 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 3-00027-7501) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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 neighborhood's founding conversion. First residential building in DUMBO, Gair's flagship tower, Higginson/Turner reinforced-concrete engineering, Beyer Blinder Belle conversion — the provenance stack here is the deepest in the neighborhood.

Historic-district protection cuts both ways. The DUMBO Historic District (2007) protects the building's context permanently, but exterior work — including windows — requires LPC approval, and façade cycles at a 1914 concrete building deserve attention. Review the current Local Law 11 status, recent financials, and any capital plan.

Understand the shared-powerhouse arrangement. Base-building systems shared with 30 Washington Street under recorded easements are a stable but non-standard feature; have counsel review the cost-apportionment framework.

Views are line-specific. The 1998 plan itself disclosed that neighborhood build-out could affect certain exposures. Walk the specific unit at multiple times of day and evaluate its particular view envelope, not the building's reputation.

Condominium flexibility is real. Right of first refusal rather than board approval; 30–45 day closing pacing; LLC and trust ownership available; no documented transfer fee.

Lead with provenance. Gair, Higginson, Turner, the clock tower, the 1998 first-conversion story, and historic-district standing distinguish the building from every new-development competitor in the neighborhood — build the marketing around the narrative alongside the square footage.

Price against authentic-loft comparables, not the DUMBO average. The neighborhood's blended dollars-per-square-foot figures are dominated by new-development trades; the correct anchors are same-line Clock Tower history and closings at peer conversions such as 30 Main Street and 70 Washington Street.

Prepare the diligence file early. Sophisticated buyers will ask about the shared mechanical easements, LL11 cycle, and post-J-51 tax treatment; transparent packaging shortens negotiations.

Condominium timelines apply. Right-of-first-refusal waiver and a 30–45 day contract-to-close cadence are the norm.
