ALTO is an architectural firm focusing on large scale cultural, community and unique development projects. We combine forward thinking contemporary design with a rigorous approach to both the technical and financial aspects of our projects. Our clients include non-profits, community based developers, fashion companies, arts clients, and various other commercial and individual projects.

We begin every project with a deep collaborative process between our clients, stakeholders and our team of designers and architects. We’re able to take on a large range of project types and scales due to the wide range of experience we’ve had on all scales and types of projects. We regularly collaborate with a variety of designers, expert consultants, engineers, and contractors to deliver complex and unique projects within budget and on schedule.

ALTO takes on all types of projects, from large multifamily commercial developments, to small restaurants as well as neighborhood non-profit projects. We take on selective residential projects through the partner’s separate residential practices.
