What Leroy Street Studio does

Leroy Street Studio is a privately held, award-winning architectural practice founded in 1995 by Morgan Hare and Marc Turkel, headquartered at 65 Allen Street in New York's Lower East Side. The firm operates as an integrated multidisciplinary studio organized around four service lines: architecture, interior design (through the LSS Interiors division led by founder-director Sybille Schneider), construction management (through affiliated BLDG Inc., established in 1995), and participatory design (through affiliated nonprofit Hester Street Collaborative, founded in 2002). This architecture–interior–construction integration enables a design-build delivery model where the firm acts as single point of responsibility for clients from concept through fabrication.

The studio serves five primary customer segments: high-end residential (custom residences, townhouses, coastal homes — the primary segment); commercial and corporate (corporate headquarters, office interiors, adaptive reuse of industrial spaces — clients include Third Point's Lever House triplex and OXO's headquarters); institutional and public (libraries, parks, environmental centers — including Brooklyn Public Library Sunset Park and Alley Pond Environmental Center, the latter LEED Gold certified); hospitality and restaurant (Charlie Bird, Pasquale Jones, Silver Sands Motel, Sweet Rehab Patisserie); and affordable housing and community development (notably 54 units of 100% affordable housing with Asian Americans for Equality). Geographic reach spans New York City, Long Island, the East End, Washington D.C., Florida, and the UK.

The firm's revenue model is professional services-based — design fees are custom-quoted per project scope with pricing not publicly disclosed — augmented by construction management fees captured through BLDG Inc. New business is won primarily through reputation, awards recognition (most notably eight or more consecutive years on Architectural Digest's AD100 list), press coverage, and referrals rather than through outbound sales. The studio currently maintains 75 or more members including co-founders, one partner (Shawn Watts, since 1997), seven recently promoted principals, and broader design and support staff, and operates as an independent partnership with no disclosed venture or private equity backing.

Direct peers

• Robert A.M. Stern Architects: Large New York-based architecture firm known for residential, institutional, and civic projects with a strong AD100 brand presence. Directly comparable to LSS in typology (custom residential, libraries, civic) and prestige tier; larger scale gives RAMSA broader bid reach but a less integrated design-build delivery model.
• Bates Masi + Architects: Hamptons-based architecture studio specializing in coastal residential and adaptive reuse projects. Strong overlap with LSS's coastal (OH50) and residential practice, sharing a craft-driven, award-winning aesthetic and similar project scale. Comparable firm size and client profile.
• Selldorf Architects: Annabelle Selldorf's NYC-based studio known for high-end residential, cultural, and adaptive reuse projects with AD100-level recognition. Comparable in scale, prestige tier, and project typology mix to LSS, with similar design-driven, award-winning positioning.
• Olson Kundig: Seattle-based architecture firm renowned for high-end custom residential and hospitality projects with strong AD100 brand recognition. Highly comparable in residential focus, craft-driven approach, and award pedigree; differs geographically but mirrors LSS's premium-residential market positioning.
• Ike Kligerman Barkley: New York-based architecture firm specializing in high-end custom residential, townhouses, and country houses. Closely comparable to LSS in project typology (luxury residential), client profile (HNW homeowners), and design sensibility, with similar AD-tier brand positioning.
• TenBerke (formerly Deborah Berke Partners): NYC architecture firm with strong residential, cultural, and institutional portfolio; similar size and AD100-tier brand. Comparable in typology mix and high-design positioning, though less integrated with construction management than LSS.
• WORKac (WORK Architecture Company): NYC architecture firm known for socially engaged design across cultural, residential, and public projects. Directly comparable to LSS's participatory design practice and Hester Street Collaborative-style community engagement approach, with similar AD100-tier recognition.
• BKSK Architects: NYC architecture firm with strong residential, civic, and adaptive reuse portfolio. Comparable project typology to LSS (townhouses, libraries, civic), similar firm scale, and shared design excellence positioning in the NYC market.
• Handel Architects: NYC architecture firm with large-scale residential, commercial, and mixed-use portfolio. Comparable in NYC market presence and residential expertise, though Handel operates at a significantly larger scale with more developer-driven work than LSS's custom residential focus.
