Rectangular, octagonal, or hexagonal, Gazebo Creations
will ship off your very own custom-designed and partially assembled modular garden structure in as little as two weeks. All you need are basic carpentry skills, a helper, and decisiveness at the outset, because the options for gazebos—as well as sheds, pavilions, playhouses, bridges, and arbors—are endless. The interactive design tool on the company's website helps you sort through the choices. From about $2,700 for an 8-foot octagonal gazebo in treated pine.
