Choosing a suitable arbor for your area or situation depends on factors such as landscape design and architecture, the overall size of the area you wish to highlight, and the budget and purpose for the structure.  If the purpose of the structure is to extend outdoor living space, then a pergola may be suitable.  If the intent of the structure is to accent or define an area, an arbor may work well.  Contact Arbors Direct, or your landscape professional, for further discussion and recommendations.
