14x20 Floating Deck: Easy DIY Construction Tips & Cost

If you're looking to enhance your outdoor living space, consider the versatile and stylish 14x20 floating deck. This deck size offers ample room for relaxation, entertainment, and even a touch of greenery. Let's delve into the advantages, planning, and construction of a 14x20 floating deck.

Before you dive into designing or building your deck, it's crucial to understand the term "floating deck." Unlike platforms attached to your home or terrain, floating decks sit directly on the ground, elevated but not permanently affixed. This makes them perfect for rentals, DIY projects, or even temporary structures.

Deck Planning and Design

Portrait or landscape? Rahling or Tetris blocks? The layout of your 14x20 floating deck can transform your backyard dynamics. Start by envisioning your ideal deck layout – consider seating areas, dining spaces, and plant beds.

Once you have an idea, sketch it out using graph paper, or utilize online design tools. Remember, your deck should complement your home's architecture. For instance, a rectangular (portrait) layout may blend seamlessly with a contemporary or modern home, while a square or L-shape (landscape) might suit a ranch or Craftsman-style house.

Foundation and Support

Before you start building, decide on your foundation. floating decks typically use concrete blocks or recycled plastic footings to elevate the deck and provide stability. Ensure these are placed evenly, level, and on solid, undisturbed ground – never on grass or soft soil.

Support beams and joists are crucial for a sturdy deck. For a 14x20 design, you might opt for 2x6 or 2x8 pressure-treated joists spaced 16 or 24 inches apart. Double check local building codes for specific joist spacing requirements.

Decking Material

Your choice of decking material can impact longevity, maintenance, and aesthetics. Pressure-treated lumber is the most affordable option, requiring annual sealing for protection. Composite materials, like recycled plastic and wood fiber, offer low maintenance but come at a higher cost.

For a 14x20 floating deck, you'll need approximately 290 linear feet of decking boards. Besides the traditional grooved and notched design, consider hidden-fastener styles for a sleek finish and easier maintenance.

Building and Final Touches

With the foundation set and materials gathered, it's time to assemble your floating deck. Start by laying out your joists, ensuring they're level, square, and parallel. Secure them to your support beams and footings using appropriate hardware.

Next, install the decking boards. Begin with the edges to allow for staggered joints and a sturdier structure. Once complete, don't forget to apply sealant to protect your deck and enhance longevity.

Safety and Permits

Safety should always be a priority. Ensure railings meet building codes and aren't higher than 42 inches. Also, consider installing post caps for added safety and aesthetics.

Before construction starts, check with your local building department for permits and requirements. While floating decks are often exempt from permits, it's always best to confirm, as rules vary by location.

Styling and Accessorizing

Once your 14x20 floating deck is complete, it's time to style it up. Consider adding planters, outdoor rugs, or built-in bench seating. Don't forget to soften the space with potted plants, hanging baskets, or even a vertical garden.

For a pop of color, paint or stain your railings or benches. You can also install LED lighting for ambiance and safety. With a little creativity, your floating deck can transform into a cozy oasis or a vibrant entertaining spot.

Building a 14x20 floating deck opens up a world of possibilities for your outdoor space. Whether you prefer a tranquil escape or a bustling social hub, your new deck is ready to elevate your backyard living. So go ahead, let your creativity flow, and enjoy the process of creating your dream deck.
