We focus on technically complex buildings requiring a high degree of integration between architectural and engineering systems. We are currently involved in over 2 million square feet of data center design and planning. We also provide full services for master planning, commercial and industrial buildings, and interiors.


Our professional services include all phases of a project, from initial conceptualization and site planning through design and construction, to occupancy. During each phase of a project, AXO Architects collaborates directly with owners, stakeholders, local officials, consultants, and contractors. Our goal is to apply to each and every phase of a project our expertise as creative problem solvers.
