Commercial Building Additions
Commercial Building Addition Services
Randahl Construction delivers seamless building additions throughout Minnesota—adding warehouse space, office areas, production facilities, and specialized environments that integrate perfectly with your existing structure while minimizing operational disruption.
Why Choose a Building Addition Over a Relocation?
Commercial building additions typically cost 30-50% less than relocating when factoring in moving expenses, business interruption, and new buildout costs—while allowing you to remain operational during construction with phased approaches that minimize downtime. You’ll maintain established customer relationships, employee convenience, and strategic market positioning while designing additional space precisely for your operational requirements rather than compromising with available properties that may not fit your business needs.
Types of Commercial Building Additions?
We design and build commercial additions across all industries—from warehouse expansions with receiving bays, loading docks, and equipment areas to office wings with conference facilities and break rooms that match your existing architecture. Our expertise includes manufacturing additions for heavy equipment and specialized utilities, retail expansions that enhance customer experience while matching storefront aesthetics, and medical facility additions with proper HVAC isolation, medical gas systems, and full regulatory compliance.
Why Choose Us?
Our self-performing team handles critical trades including framing, concrete, and millwork directly—ensuring superior quality control while seamlessly integrating new construction with existing buildings through specialized structural tie-ins, weatherproofing transitions, and architectural matching refined over 40 years. We plan meticulously to keep your business running, coordinating construction phases around your operations to minimize impact on employees and customers. With detailed estimates accounting for every project element and no surprise change orders, President Randy Olsen personally conducts project walk-throughs to ensure industry-leading service and craftsmanship on every addition.
