Insightful construction and real estate services since 2003

KC MASS Services operates at the intersection of construction, real estate, and the built environment—delivering projects with clarity, control, and accountability. Based in Kansas City, we partner with developers, property owners, and institutions to move projects from concept to completion with a fully integrated approach.

Our work spans construction execution, real estate advisory, and owner representation, allowing us to guide decisions at every stage of a project. We specialize in adaptive reuse, accessibility-driven design, and residential and mixed-use development—transforming both new and existing assets into high-performing environments aligned with real-world needs.

Founded in 2003, KC MASS has evolved from a traditional construction and brokerage firm into a strategic partner focused on project leadership and asset performance. Our role as an owner’s representative ensures that our clients’ interests are protected by coordinating teams, managing budgets, and maintaining accountability across all phases of development.

Led by Mark Irvin, whose lived experience as a paraplegic informs deeper design and usability insights, KC MASS brings a perspective that goes beyond compliance—focusing on how spaces truly function for the people who use them.

We approach every engagement with a focus on execution, alignment, and long-term value—helping clients make informed decisions and deliver projects that perform.
