Comfortable seating is imperative, and plantscaping is essential, whether it’s done as [permanent] landscaping or in containers and pots. Fireplaces or fire pits contribute to a cozy environment, while water features can contribute to a relaxing space. —Kim McOwan, Charette Interior
I like to start with rugs, just like I do for interiors spaces. [A rug] defines the geometry of a space from the ground up. Once the rug is down, create one seating area for eating and another for lounging and conversation. Tie them together with accessories. Seat cushions for both areas should always be in a standard solid color for two reasons. If you get a permanent stain on a cushion, you want to make sure you can replace it. Second, your outdoor space will look too busy if all the seat cushions are prints. —Debra Funt, Debra Funt Interiors
Keep it informal and easy. Materials have to be comfortable on bare skin exposed in the warm weather, surfaces must clean easily from food spills, and the area has to be conducive to candlelit dinners. Indoor/outdoor rugs are my favorite. They dress up and define a space and clean up with a hose. It doesn’t get better than that. —Katherine Stern, Katherine Stern Design
