A floating deck, also known as a cantilevered deck, is a type of deck that appears to be floating in mid-air due to the clever use of structural supports and railings. This style of deck is particularly popular in areas with a high water table or where the soil is unstable, as it allows for a more open and airy feel without the need for extensive foundation work.

Choosing the Right Location

When selecting a location for your floating deck, it's crucial to consider the structural integrity of your home and the surrounding terrain. You'll want to ensure that the deck is securely attached to the house and that the soil beneath it can support the weight of the deck and its occupants.

Take into account the slope of your yard and the direction of any water flow. A floating deck should ideally be situated in a spot where it will not collect water or create a slippery surface. You may also want to consult with a professional to determine the best location for your deck, taking into account factors like sunlight, wind direction, and potential obstructions.

Selecting the Right Materials

When it comes to selecting materials for your floating deck, you'll want to choose durable, weather-resistant options that can withstand the elements. Pressure-treated lumber, composite decking, or hardwoods like cedar or redwood are popular choices for floating decks due to their ability to resist rot, decay, and insect damage.

Don't forget to consider the weight and load-bearing capacity of your deck when selecting materials. You'll want to ensure that your deck can support the weight of its occupants, as well as any furniture, decorations, or other items you plan to place on it.
