Creative Outdoor Sheds

Custom storage shed builders in Wisconsin

Custom Built Storage Sheds in Wisconsin and Illinois

Mainus Construction specializes in bringing your dream shed to life. Our sheds are built exclusively with quality materials strong enough to withstand brutal Midwest weather, because there’s nothing worse than investing in your outdoor storage space only for it to be brought down by average wind speeds. 

Whether you’re looking for traditional storage space for your tools, a wood working shop away from the main house, a pool house to host parties in the summer, or a custom built playhouse any kid will enjoy, we have the architectural designers and carpenters to build it.

Storage Shed Solutions

Our shed templates get you started on your custom order. We have traditional styles including gable shedssaltbox sheds, and barn sheds which come pre-built and delivered to your property, or built directly on the space you want. These sheds act as:

  • Outdoor storage for lawn mowers & tools
  • BBQ equipment storage
  • Gardening sheds
  • Sheds for patio furniture
  • Storage sheds for bikes, boards, and other exercise equipment

And much more—every shed is built with your unique needs in mind. Contact Mainus Construction today to get started or get inspired by our shed gallery.

Outdoor Sheds for Any Use

Just because it’s a shed, doesn’t mean it has to store traditional equipment. We have the right design team to build you a shed fit for any need outside of storage. If those pre-built plastic sheds from big box stores just can't fit your needs, then Mainus Construction will design and build you the creative space you've always wanted. Our outdoor sheds can be fabricated with custom design elements, including:

  • Electrical work
  • Lofted spaces
  • Large windows
  • French doors
  • Overhangs for small porches

And more, our customizable shed templates can be altered to your specific needs to match your house or set the shed apart from it all.
