About Lasse Aspelin & Associates

Architecture is more than how a building looks—it’s how a space works for the people who use it. At Lasse Aspelin & Associates, we provide architectural services for custom homes, renovations, additions, and commercial projects throughout Connecticut, southern Massachusetts, and Southern New England. Founded in 1982, we continue to deliver thoughtful design solutions tailored to each project.

Educated at California State Polytechnic University, Lasse Aspelin & Associates furthered his studies in Scandinavian architecture, design, and lighting in Copenhagen and Helsinki. That foundation informs a thoughtful approach to creating beautiful, functional spaces.

With more than 500 projects completed across the public and private sectors, our experience spans residential, commercial, educational, healthcare, and community facilities. Our services include architectural and interior design, feasibility studies, land planning, code analysis, construction administration, and project management.

From exploring your first ideas to navigating construction, we work closely with you to balance your vision, budget, and schedule—with professional service and clear guidance.
