Check the area for any needed repairs. Prior to your first entertaining session, look over the deck or patio and take note of any flaws that may present safety hazards. Are there any loose railings? Are all screws and nails flush so they don't cause tripping? Are there any cracks in concrete or loose patio blocks? Be sure to remedy all of the repairs needed to ensure guests will be safe. If you are unsure of any structural deficits, consult with a professional.
Think about closing in a portion of a deck or patio. The use of a canopy, netting or even greenery to protect an entertaining space can help minimize weather-related damage to outdoor furniture. Netting will keep a good number of biting insects at bay when the weather is warm and humid. Having a bit of concealment also means you can create a private space that isn't easily viewed by neighbours or passersby.
Plan well-defined areas. Just as rooms serve different purposes inside of a home, outdoor areas can be separated according to usage. Establish a sitting nook where guests can gather and talk. Have a bar or serving area where refreshments are made and served. Make sure there is a shaded area for when the sun is too uncomfortable to make sitting outside enjoyable. Similarly, have a sunny area where people can soak up a few rays or dry off after a dip in the spa or pool. Don't forget to establish a spot for the kids to converge with scaled-down amenities.
Invest in quality outdoor furniture.
Guests no longer want to sit on uncomfortable metal or plastic furniture. There are many different outdoor sofas and chairs that are as stylish as they are comfortable. These pieces can be matched to the decor inside your home for a cohesive look.
Accessorize. Don't shy away from hanging artwork on an exterior wall or using urns or pottery to decorate the space. Think about having an entire set of serving dishes and other entertaining items for the outdoors.
