The Power of Integration.

Most firms specialize in either architecture or engineering. Arium does both, and more.

With in-house architects, MEP engineers, and interior designers working as one team, we streamline timelines, improve communication, and deliver smarter, more coordinated results. For over 37 years, we’ve helped clients across the Mid-Atlantic build spaces that perform as beautifully as they look.

What Sets us Apart

Proven in the Field.

Our work spans sectors, styles, and challenges, but every project shares a common thread: integrated design, balanced by form and function, delivered by one team.
