Free online courseHow to build a Garage

Course Description

Learn how to build a garage with practical construction know-how you can apply on real projects, whether you’re upgrading your own property or building job-ready skills in the trades. This free online course follows the same logic used on professional builds, taking you from early groundwork decisions to the finishing details that make a structure solid, functional, and long-lasting. You’ll gain confidence working across the key systems involved in garage construction, including layout, foundations, concrete work, framing support concepts, openings, basic stair building, electrical, and plumbing.

You’ll start by understanding what needs to happen before concrete is ever poured: planning for utilities, preparing excavations, and setting up footers correctly so the structure is supported where it matters most. From there, you’ll connect the reasons behind good foundation prep with real techniques used on-site, including establishing consistent elevations and achieving stable formwork. Concrete work is covered with an emphasis on getting reliable results and appreciating the difference between a surface that merely looks finished and one that will perform under daily use, weather changes, and vehicle loads.

As the build progresses, you’ll move into the parts that affect usability and fit: installing windows efficiently, handling rough openings properly, and solving common wall-thickness challenges with door jamb extensions. You’ll also learn core concepts that keep framing and structures rigid and safe, helping you understand why bracing matters and how small details can prevent long-term movement and headaches.

To round out professional skills for a modern garage, the course addresses essential utility work. You’ll explore plumbing under slab, correct drain slope for good flow, venting considerations, and practical PEX installation guidance. On the electrical side, you’ll see how to approach sub-panel wiring details, how outlet standards like NEMA matter for matching equipment, and how a 240V outlet can support tools, welders, or EV charging. Finally, you’ll cover exterior finishing touches like soffit and fascia so the structure looks clean while managing ventilation and weather protection. By the end, you’ll have a clear, start-to-finish picture of how a garage comes together and what quality workmanship looks like at every stage.
