Small Floating Deck DIY: Step-by-Step Guide

Looking to enhance your outdoor living space without breaking the bank? A small floating deck is the perfect DIY project to create a cozy, inviting area to enjoy the sun and fresh air. Not only is it a cost-effective way to expand your home's footprint, but it also adds value to your property. So, let's dive into creating your dream floating deck, step by step.

Before you start, remember that planning is key to a successful DIY project. Set a budget, decide on the size and shape of your deck, and choose the best materials for your needs. Also, ensure you check local building codes and obtain any necessary permits to avoid potential headaches down the line.

Materials and Tools

For a typical small floating deck (around 100-200 sq. ft.), you'll need the following materials:

• Pressure-treated or composite decking boards
• 4x4 or 6x6 pressure-treated posts
• 3-1/2" and 2-1/2" galvanized screws
• Post-to-beam hangers
• 3/4" pressure-treated plywood
• Gravel and landscape fabric

As for tools, you'll need:

• Circular saw
• Drill and driver bits
• Level and tape measure
• Post hole digger or auger
• Wheelbarrow
• Gloves and safety glasses

Designing Your Floating Deck

Floating decks are elevated but don't have a staircase, so it's essential to choose a height that allows easy access. Most homeowners opt for a height ranging from 12 to 18 inches. Decide on a simple, easy-to-build shape like a rectangle or square, and sketch a basic layout including size, location, and position of beams and posts.

TIP: Consider hiring a professional to help design and plan your floating deck for added peace of mind.

Preparing the Site

Before you start building, remove any obstacles from the area, such as grass, plants, and rocks. Then, lay out the design using stakes and string for a clear reference. Next, dig post holes at least 8" in diameter and deep enough to place the posts below the frost line (check local building codes for the exact depth).

Pro tip: Fill the post holes with gravel and landscape fabric to prevent water from pooling around the posts and causing rot.

Building the Deck Framework

Now that your site is ready, it's time to assemble the deck framework. Start by cutting the posts and attaching them to the posts-to-beam hangers using 3-1/2" screws. Make sure the posts are square and plumb. Then, attach the beams to the hangers using 3-1/2" screws, ensuring they're level and evenly spaced (around 16" on center).

TIP: Always wear safety glasses when using power tools and working with screws to protect your eyes from debris.

Installing the Deck Joists

Cut the joists to fit between the beams, and attach them using 2-1/2" screws. Space the joists 16" on center, ensuring they overhang the beams by at least 1.5". You may want to lay out the joists on the ground before installing them to ensure they fit perfectly.

Pro tip: Double-check that the deck is square by measuring across the diagonals. If they're equal, your deck is square, and you're on the right track!

Adding the Decking Boards

Now that the framework is complete, it's time to install the decking boards. Start at one corner, and use a staggered pattern (double the width of the joist spacing) for added stability. Secure the boards with 2-1/2" screws, ensuring they're level and evenly spaced.

TIP: To avoid nail pops or screw backs out over time, drill pilot holes before inserting screws and use a countersink bit to recess the screw heads.

Finishing Touches

Once the decking is complete, give your floating deck a final once-over to ensure everything is secure and square. Then, consider applying a stain or sealer to protect the wood and enhance its appearance. Or, if you've chosen composite materials, simply clean and maintain them according to the manufacturer's instructions.

Lastly, inspect your work and take pride in knowing you've added a beautiful, functional space to your home without breaking the bank.

Embrace your newly-created outdoor sanctuary, and remember that regular maintenance will help preserve your deck's longevity. Go ahead, invite friends and family over for a relaxing get-together – your floating deck is ready and eager to host!
