Garages, Sheds, Outbuildings & ADUs
Design | Build | Love
Northern Builder Co-op LLC designs and builds custom garages, sheds, outbuildings, and Accessory Dwelling Units (ADUs) throughout the Twin Cities west metro. Whether you need a three-stall detached garage, a craftsman workshop, a storage shed that matches your home's character, or a fully finished ADU for rental income or multigenerational living — we build structures that are functional, durable, and designed to complement your property.
Why Add a Garage, Outbuilding, or ADU?
Increased Property Value
A well-built detached garage, finished outbuilding, or ADU adds meaningful square footage and usable space — consistently one of the highest-return investments a homeowner can make.
Versatile Use Cases
From vehicle storage and workshop space to home offices, hobby studios, and guest quarters — outbuildings and ADUs adapt to your lifestyle now and into the future.
Rental Income Potential
A finished ADU above a garage or as a standalone unit can generate consistent rental income, helping offset your mortgage or build long-term wealth.
Multi-Generational Living
ADUs provide a private, comfortable space for aging parents, adult children, or extended family — keeping loved ones close while preserving everyone's independence.
Investment Range
Project costs vary based on size, complexity, and finish level. As a general guide: basic storage sheds and outbuildings start around $30,000–$60,000; detached garages typically range from $60,000–$150,000+ depending on stall count and finish; and ADUs (attached or detached) start at $200,000. All pricing reflects quality materials, proper permitting, and craftsmanship built to last.
What We Build
Detached Garages: Single, double, and triple-stall garages with options for finished interiors, insulation, heating, epoxy floors, built-in storage, and second-story bonus rooms or loft space.
Workshop & Hobby Sheds: Purpose-built structures for woodworking, mechanics, art studios, or any hands-on pursuit — wired for power, insulated for year-round use, and sized to fit your workflow.
Storage Outbuildings: Durable, weather-tight storage buildings designed to match your home's exterior — ideal for lawn equipment, seasonal gear, tools, and recreational vehicles.
Accessory Dwelling Units (ADUs): Fully permitted, code-compliant ADUs — attached, detached, or above-garage — complete with kitchen, bath, bedroom, and living space. Designed for rental, guest, or multigenerational use.
Pool Houses & Cabanas: Stylish poolside structures with changing rooms, wet bars, outdoor kitchens, or lounge space — built to complement your outdoor living area and extend your entertaining season.
