12×20 DIY Lean To Carport Plans

Give your vehicles the protection they deserve with our detailed plans for a 12×20 slanted roof carport. This striking design is a contemporary architectural masterpiece, moving beyond a simple shelter to become a deliberate, sculptural feature. The sleek, sloped roof isn’t just modern in style – it’s engineered to direct rainwater and minimise snow buildup, while the semi-enclosed structure provides superior protection from the elements.

The defining characteristic of this carport is the integration of walls and screens. The plans include a full back wall composed of horizontal slats, providing a solid backdrop that shields your vehicle from wind, rain, snow, and debris. The sides feature unique, decorative screens consisting of horizontal slats set into angled support posts, creating a dynamic sense of movement and visual interest while maintaining a feeling of openness. These screens offer partial protection from crosswinds and angled sun without creating a fully enclosed space.

Despite being more enclosed, the slatted side screens and open front ensure excellent air circulation, preventing moisture and heat from becoming trapped inside. Sized to accommodate most standard vehicles, including SUVs and pickup trucks, the carport’s generous dimensions of around 12×20 feet provide ample space for parking and opening doors without feeling cramped. Access is straightforward from the open front.
