Have a curvy pool design? Don’t sweat it. TimberTech decking can be curved to fit your space for an elegant, fluid design.

Ideas for back deck designs apply to rooftop decks too

Rooftop Deck Designs

Don’t have a backyard? Build a deck on your roof. Rooftop deck designs are seriously modern and offer you a peaceful retreat from the busy streets below.

Enhance the sense of escape with lots of greenery and warm deck lights to give your space a calming, natural feel.

Back deck designs featuring multiple levels

Multi-Level Deck Designs

Multi-level deck designs don’t only refer to decks charting multiple stories. Levels need only be separated by one or two steps to give your design greater depth and dimensionality.

Multi-level decks also feature improved functionality by creating different sections for different uses.

Back deck designs with covered deck features

Covered Deck Designs

Covered deck features come in many sizes and styles. A roof extension or screened-in section gives you complete overhead protection and is often designed in the same style as your home.

Explore Back Deck Designs by Shape

One of the most important aspects of back deck designs is shape. The ideal deck shape for your build will depend primarily on the space available and how you intend to use your deck. Spacious designs like wide squares or rectangles will allow for larger gatherings, while tighter angled shapes like hexagons will be more conducive to smaller, intimate gatherings.

Common deck plans include:

Back deck designs with traditional shapes

Traditional Shapes

Squares and rectangles are classic, highly versatile deck shapes that can fit in almost anywhere. A wraparound deck gives you lots of functional space without taking up too much of your backyard.

Back deck designs with angled shapes

Angled Shapes

Go for a modern geometric design with various angles in your design. Hexagons and octagons are common additions to a traditional shape and give your deck a smaller section for more intimate gatherings.

Back deck designs with curved shapes

Curved Shapes

Curved designs give your deck an unexpected but elegant look. Incorporate curves into your deck surface or along your deck perimeter for a fluid design that complements the landscaping.

Size considerations for back deck designs

What’s a Good Size for a Deck?

Your deck’s size should be proportional to your backyard and your home, while also aligning to your project budget.  

You’ll also want to make sure your deck is the right size to accommodate the deck’s primary functions. So, whether you prefer to throw large dinner parties or simply enjoy the deck with the one you love — your deck is the right size.
