Building a standalone garage away from any building requires a slightly different strategy than when attached to your home.

In comparison, the car park area features a large garage door for your car and large garden equipment.

Each video shows a significant addition to the building, so ensure you carefully follow the 7-day series. The roof was built on the ground and mounted on the post once it was set in concrete. This process is more accessible than building the roof on wooden posts; however, it’ll require a considerable workforce or heavy-duty equipment to raise the roof.

This standalone garage is large enough to accommodate two cars, with extra room for storing other garden equipment or workshop materials. It features a hip roof design for the garage area and a ceiling type that expands the storage area above with the porch area beside the garage, providing room to enjoy on a rocking chair or outdoor cushion.
