There are many uses for gazebos as well as different styles. There are those that are made with just a tent shade canopy that you can buy or rent to use for parties and cookouts. And there are also more sturdy gazebos that are built to be more permanent. But if you want to get really creative, you can have one custom made for you.
It all depends on your needs. If you are planning a simple family BBQ or outdoor birthday party, for example, you might want to rent a simple standard gazebo with a tent canopy. But if you are planning a special event such as a small wedding reception or a small graduation party, you might want something a little fancier.
If you are planning a large event such as a large wedding reception with all the trimmings or a large family reunion, an 8×8 gazebo will most likely not suit your needs. You would need a much larger gazebo or more than one small one. Maybe, you just need a simple but nice permanent gazebo to put your patio furniture inside of.
You can find many standard size and standard type gazebos with the tent canopy at places like Home Depot and Lowe's. Other styles that are more durable include the hexagon-shaped heavy wrought iron gazebo. It has six sides with three windows and three open doors. These run in the lower thousands.
There are some unique 8 x 8 gazebos that are made by individual carpenters. There is one, in particular, advertised on eBay that is made like a garden hut that has a metal roof with windows. It is made of cedar wall panels with lattice for ventilation and Plexiglas-glass windows. It has wrap around benches in it that will seat 8-10 people and is also handicap accessible. These can be customized to your liking or you can even have one built from scratch according to your wishes.
Before you decide on what type of gazebo you want, you should determine your long-term needs for it. If you want it to be permanent and you plan to use it often, you should invest in a good, sturdy gazebo that can withstand strong winds and bad weather. But if you just need one here and there for an occasional special event, you should consider the option of renting one rather than buying one.
