The beams of a deck are allowed to cantilever beyond the end posts, extending up to one-quarter of the beam span between the posts. This allows for a slight reduction in the space between the posts, as the beam can be made smaller. The dimensions of the span of the beam and the cantilever are taken from the center of the posts, not from the face of the posts. A cantilever platform is an excellent way to expand your outdoor living space and take advantage of views that wouldn't be available with a traditional terrace.
This type of platform is supported by joists that extend from the house onto a beam. Cantilever roofs are usually constructed with stronger materials than other types of roofs, since they need to support the weight of the cantilever. Now that you have a better understanding of roof overhangs and their advantages, you can confidently move forward with your cantilever platform project. Cantilevering is an effective way to maximize your outdoor living space while taking advantage of views that wouldn't be available with a traditional terrace.
It is important to understand how far a deck beam can overhang a post in order to ensure that your project is safe and structurally sound. By following these guidelines, you can ensure that your cantilever platform will be safe and secure for years to come.
