Building Better for People, Place, and Future

Since 1996, we’ve partnered with developers and building owners to thoughtfully integrate design, materials, and technology, delivering high-performance spaces built for the long term.

We are celebrating Our 30th Anniversary! 30 Years Strong. Here’s to Building What’s Next.

Building with Purpose for 30 Years

Founded in 1996 (originally as Bazzani Building Company), Cella Building Company is a Grand Rapids–based construction firm focused on high-performance, sustainable development and commercial construction. For nearly three decades, we’ve helped owners and developers build with clarity, accountability, and long-term value in mind.

A Thoughtful, Proactive Approach

We start by listening; understanding owner goals, user needs, site conditions, and project context. By asking the right questions early and collaborating closely with partners, we help teams make informed decisions and reduce risk throughout the construction process.

 

Sustainability is embedded in every project we deliver. Through performance-driven materials, thoughtful construction management, and responsible building practices, we create durable, efficient spaces that serve communities across West Michigan and beyond.
