D. A. Hall Architect, PC is a full service architecture and interior design studio founded in New York City by the firm’s principal, Denise A. Hall, AIA. Now Philadelphia-based, the firm’s portfolio consists of a wide variety of projects — residential, cultural, hospitality, industrial and retail — at varying scales and levels of complexity.

Our service and expertise ranges from initial site selection and program development through to project completion and move-in. Diverse and eclectic, our work has included historic restoration, renovation and new construction, retail branding, and landscape, lighting and furniture design. Our tailored services provide tailored solutions that are comprehensive in scope and based on the individual needs of each client and project type. In all our work we are committed to employing sustainable systems and strategies to ensure a responsible use of natural resources and a keen respect for all environments.

The firm is studio-based, with all projects designed and coordinated by the principal, ensuring continuity, consistency and clarity of communication throughout. The core staff is supplemented by a team of specialized outside consultants, technical experts and artisans bringing expertise, passion and enthusiasm to every project.

Our design process is one of first listening, questioning, analyzing, drawing and finally building — addressing needs that are both practical and intangible. “Design is always about thinking, and I think by drawing,” says Hall. Ideas are defined and refined through a series of drawings until the “right” one appears — right for the time, the place, the client and the budget.

With this emphasis on analytical, collaborative and innovative problem solving, the firm has executed projects in the US, Europe and the Caribbean. Quality is the defining factor — quality of thought, purpose, design and execution.

we believe the practice of architecture is a
service • passion • process • responsibility • delight
