330 Spring Street

The building's signature is its glass. Full-height glazed walls flood the residences with light and frame downtown and river views, with remote-controlled shades managing privacy and sun — a direct architectural reference to Johnson's original Glass House, reinterpreted for vertical urban living. The detailing is restrained and precise, in keeping with both Johnson's late vocabulary and Selldorf's interiors.

The 40 residences, including a penthouse, are finished to a high specification — stainless-steel kitchens and contemporary baths within open, light-first layouts. The homes run generously, and the glass walls give even mid-floor residences a sense of openness that masonry buildings cannot match. The penthouse crowns the building as its signature home.

The Urban Glass House runs as a full-service condominium, with an attended lobby and fitness facilities serving its 40 households. The building's scale keeps it intimate while its staffing keeps it convenient — a balance that suits the design-minded buyer it attracts.

As a condominium, ownership is flexible: financing is not capped the way it is at a co-op, pied-à-terre and investment purchases are customary, and resale and subletting are materially freer than at the surrounding co-op stock. Purchases clear through a right-of-first-refusal rather than a co-op board admissions process — a lighter, faster path that the building's buyers value.

With 40 residences, the Urban Glass House trades modestly — a handful of homes change hands in a typical year, and a building with this design pedigree draws focused, qualified demand when they do. Pricing tracks the Hudson Square and downtown condominium tier and scales with square footage, floor, light, view, and renovation depth, with the higher floors and the penthouse commanding the strongest numbers. The Johnson-Selldorf provenance is a durable premium that sets the building apart from generic glass inventory. Our read on value is grounded in the building's design, light, and the condition of the specific residence, not in any single headline trade.

The case for the building is twofold: architectural provenance — Johnson's final work, with Selldorf interiors — and the light-first living the glass envelope delivers. Buyers should evaluate each home for its exposure, floor, and view, since the value of a glass building lies in what the glass frames. Higher floors and the penthouse carry a premium that reflects both the views and the scarcity of comparable design-pedigree inventory downtown.

Because it is a condominium, financing latitude is wide and the closing path is lighter — a right-of-first-refusal rather than a co-op board package and interview. For buyers weighing a downtown co-op against this building, that flexibility, plus the architectural pedigree, is often decisive.

The marketing core is the pedigree: Philip Johnson's last building, with interiors by Annabelle Selldorf, a glass envelope that references one of the most famous houses in American architecture. That story is unique and durable — it separates a resale here from any conventional glass condominium downtown. Sellers should foreground the provenance, the light, and the views, alongside the condominium flexibility.

Inventory is limited and turnover unhurried, so a well-prepared listing competes against few direct peers. Pricing should be benchmarked against the building's own activity and the small set of comparable Hudson Square and downtown condominiums, with light, view, and condition driving the final number. Condominium closing mechanics make for a faster, more predictable transaction — itself a selling point to the flexibility-minded buyer the building attracts.
