O'Neil Langan Architects was established in 1996 combining the expertise of partners Steven O’Neil and Mary Langan. The two architects share a commitment to creative design as well as a dedication to providing professional service. With a rapidly growing practice of young designers and architects, the team delivers consistent service to clients, exciting design solutions, and meticulous detailing. Since its inception the firm has expanded to more than 50 employees in Manhattan, with projects all over the world.

OLA’s portfolio is rich and diversified, but always seeks to bring a fresh approach to design problems.

OLA has extensive experience in working with new brands that are evolving in the US and International retail market. Many of our clients have come to us as start-ups and we have developed stores with them as their brand recognition grows. We maintain one Principal, one Associate and one Senior Project Manager to liaise with the brand and organize the client’s and consultants teams. We deliver projects efficiently, with time sensitive schedules by managing our staffing and taking the lead in coordinating with the client to see that information is received and channeled so that milestone schedule dates are met. The leadership of the principals demonstrates to our staff the goals of dedicated professionalism, accuracy and effective project management.
