Adding a deck to your home increases its value and adds outdoor living space. Choosing a shape, the size and furnishings, such as benches and planter boxes can be difficult. Designing a deck online takes the guesswork about what your deck will look like after it's completed. Many online tools have 3-D options, and some will print a list of materials you'll need to build the deck. Most garden design programs have a deck option. All of the programs listed here are intuitive and easy to use.
