Eric Reinholdt

Eric Reinholdt designs simple modern homes and shares the architecture process through 30X40 Design Workshop, his widely followed studio, YouTube channel, and resource platform.

Eric W. Reinholdt is the founder of 30X40 Design Workshop, a Maine-based residential architecture studio known for designing simple, modern, site-specific homes. Working from Mount Desert Island near Acadia National Park, Eric creates houses shaped by landscape, climate, light, craftsmanship, and the lived realities of his clients.

Founded in 2013, 30X40 Design Workshop approaches residential architecture through an idea-driven and collaborative design process. Eric’s work is recognised for its restrained material palette, attention to detail, and a modern sensibility informed by humble building forms and the character of the local environment. Many of the studio’s projects are based in Maine, though the practice also works on commissions throughout the United States.

Beyond his architectural practice, Eric is also widely known as an architect, entrepreneur, author, and educator. Through the 30X40 Design Workshop YouTube channel, he openly shares the design process, creative workflows, and practical insights behind running an independent studio. His videos are used by students and professionals worldwide and have helped make the channel one of the most visible architecture-focused platforms online.

Alongside built work, 30X40 has developed a substantial ecosystem of resources for designers, including courses, drawing tools, templates, and guidance for small independent practices. This combination of residential design, process transparency, and professional education has made Eric a distinctive voice within contemporary architecture.

Eric’s work and platform have received broad recognition, including design awards, major publications, and a YouTube Gold Play Button for surpassing one million subscribers.
