Platform Method

The platform method involves building a platform on top of the ground using 2x6 or 2x8 pressure-treated lumber. This platform serves as the foundation for the deck, providing a level surface for the deck boards to sit on. The platform method is a popular choice due to its simplicity and effectiveness.

However, the platform method has its drawbacks. For example, it can be time-consuming to build the platform, and it may require additional support beams to ensure the deck's stability.

Beam and Post Method

The beam and post method involves installing a series of beams and posts to create a floating deck. This method is often used for larger decks or those with complex designs. The beam and post method provides a more stable and durable option, but it can be more expensive and time-consuming to install.
