What’s the difference between a Floating Deck and a ground level deck?
What Are Ground Level Decks? A ground-level deck, sometimes referred to as a floating deck or platform deck, is so-called because, unlike conventional decks, a ground-level deck is not attached to a home or building. While a floating deck might be next to a building, it may also be a standalone structure in the middle of your yard.
