 Whether you’re expanding your living space or adding a new garage, we build projects that blend seamlessly with your existing home or property.

Our most requested services include:

• Home additions & room expansions 
• Attached & detached garage construction
• Garage conversions
• Basement finishing & conversions
• Home offices, guest suites & flex spaces
   

Every project is custom designed to meet your needs, budget, and local building requirements.

If your home feels cramped or no longer fits your needs, a room addition or conversion can be the perfect solution. We help homeowners turn unused or underperforming spaces into comfortable, functional rooms designed around how you actually live.

From expanding existing rooms to converting garages, basements, or attics, Nationwide Construction delivers smart layouts, quality craftsmanship, and code-compliant construction—without the disruption of moving.

Whether you need a home office, guest room, extra bedroom, or flexible living space, we build it to feel like it was always part of your home.

 A garage is more than a place to park — it’s protection, storage, and adds to property value.

We build custom garages designed for durability, functionality, and long-term use.

Garage construction options include:

• Attached garages 
• Detached garages
• Expanded or multi-car garages
• Garage storage & workspace / shop builds
• Garage-to-living-space conversions
   

We ensure proper foundations, framing, roofing, and code compliance for a structure that lasts.

 Nationwide Construction proudly serves Missoula and nearby communities in Western Montana. Our local experience ensures your addition or garage project meets all regional requirements and weather considerations.
