Who CB Developers is
CB Developers is the Manhattan development firm of Charles Blaichman, a developer with more than three decades of New York work — including the Urban Glass House at 330 Spring Street, the final project designed by Pritzker laureate Philip Johnson. Blaichman's firm is best known for building in partnership rather than alone: it has long teamed with SK Development (the Shnay family's firm) and, on many projects, with Ironstate Development, under the "CBSK" banner.
The two buildings on this site are both CB Developers / SK Development joint ventures. For a buyer, that co-development structure is the key fact: design, delivery, and sponsorship responsibility on both projects sit with the partnership, and CB and SK should be read together as the sponsor.
Buildings by CB Developers
CB projects profiled on this site — both joint ventures with SK Development:
- 214 West 72nd Street (Parker West) — a 2021 Upper West Side condominium of just 18 full-floor and duplex residences, designed by GRADE New York with GreenbergFarrow as architect of record (developed with SK Development and Brooklyn Standard)
- 401 East 51st Street (Beekman) — a ground-up, 29-story, 83-residence Turtle Bay condominium designed by SLCE Architects
Reputation and what a buyer should know
On build quality, we found no construction-defect litigation or homeowner-defect complaint against these CB / SK condominiums, both of which read as well-executed contemporary product. The honest framing is one of attribution: both are partnerships with SK Development (Parker West also involved Brooklyn Standard), so a buyer weighing sponsor track record should read CB and SK together and do the usual building-level diligence — offering plan and current financials, lien and title status, warranty and punch list.
The Roebling Team on CB Developers buildings
We publish developer profiles because a buyer choosing a new-construction condominium is, in part, betting on the developer — and on these two buildings, that means a well-established CB / SK partnership with a long Manhattan track record. We bring that building-by-building context to every new-development transaction.
