Floating Deck Ideas: A Detailed DIY Guide

Are you looking to enhance your outdoor space with a stunning floating deck? You’ve come to the right place! In this comprehensive guide, we will walk you through the process of building a floating deck step by step. Whether you’re a seasoned DIY enthusiast or a beginner looking to take on a new project, this guide is designed to help you create a beautiful and functional outdoor oasis.

Materials Needed

Before you begin building your floating deck, it’s important to gather all the necessary materials. Here’s a list of what you’ll need:

  • Pressure-treated lumber
  • Concrete deck blocks
  • Joist hangers
  • Galvanized screws
  • Drill
  • Circular saw
  • Level
  • Tape measure
  • String
  • Decking boards
  • Stain or sealant

Step 1: Planning and Design

The first step in building a floating deck is to plan and design your project. Consider the size and layout of your deck, as well as any specific features you want to include, such as built-in seating or a pergola. Make sure to check local building codes and obtain any necessary permits before starting construction.

Step 2: Site Preparation

Clear the area where you plan to build your deck of any vegetation or debris. Use a string and stakes to outline the perimeter of your deck and ensure it is square and level. Place concrete deck blocks in each corner and at regular intervals along the perimeter to support the joists.

Step 3: Building the Frame

Construct the frame of your floating deck using pressure-treated lumber and joist hangers. Attach the frame to the deck blocks using galvanized screws, making sure it is level and square. Add additional support beams as needed to ensure the structure is sturdy and secure.

Step 4: Installing Decking Boards

Once the frame is in place, it’s time to install the decking boards. Lay the boards perpendicular to the joists, leaving a small gap between each board for drainage. Secure the boards in place using galvanized screws, making sure they are evenly spaced and level.

Step 5: Finishing Touches

After installing the decking boards, apply a coat of stain or sealant to protect your deck from the elements and enhance its appearance. Add any finishing touches, such as railings or built-in seating, to complete the look of your floating deck.


Congratulations, you’ve successfully built your very own floating deck! With the right materials, tools, and a bit of DIY know-how, you can create a stunning outdoor space that you’ll enjoy for years to come.
