CBSK Ironstate
CBSK Ironstate is a New York City-based real estate development partnership formed by CB Developers, SK Development, and Ironstate Development. Based in Manhattan, the firm has completed multiple residential and mixed-use projects and maintains a development pipeline in the hundreds of millions of dollars. Its portfolio focuses on premium rental apartments and condominiums in Manhattan neighborhoods like Murray Hill and Midtown East. For example, The Frontier at 200-210 East 39th Street in Murray Hill is a mixed-use rental complex with 24-hour doormen, a landscaped rooftop lounge, a fitness center, package storage, and in-unit laundry; it is also pet-friendly. Apartment interiors feature bamboo wood floors, Liebherr and Bosch appliances, custom bathroom vanities, and other upscale finishes. The Frontier even includes on-site income-restricted units to broaden access for renters.
CBSK Ironstate also develops condominiums, offices, retail, and hospitality properties. For example, The Lindley at 591 Third Avenue in Murray Hill is a 20-story full-service condominium tower. The partnership's portfolio extends to boutique hotels such as Pod Brooklyn in Williamsburg and commercial projects like the 363 Lafayette Street office building in NoHo. Across its projects, the firm emphasizes smart, sustainable design and community integration. Each development is thoughtfully planned with quality construction and modern features. Renters benefit from well-appointed living spaces and ample amenities that support convenient, urban lifestyles.
