What Different Deck Shapes Are Popular?
Decks aren’t only functional additions to your home; they are design statements. One of the most important elements of your deck design is its shape.
The shapes listed below are some of the more popular ones and include more classic shapes such as squares and rectangles, as well as more daring shapes like octagons and softly curved designs. Each can be customized to suit your home’s aesthetic, so whether you live in a Craftsman, Cape Cod, or a mid-century modern home, you can find the shape that suits your style best.
When choosing from the different styles of decks available, keep in mind that the deck shape you choose should:
- Complement your home’s structure and architectural style.
- Optimize the use of the space around it.
- Balance the overall look and feel of your home.
Our customizable deck plans give you a great jumping-off point for creating a personalized outdoor living space that will become the envy of the neighborhood.
