The anatomy of a pergola consists of a number of component parts seen in the elevation above. The height of the pergola is typically 8'10" from base to top of lintel with other heights available. Column spacing is pre-engineered up to 12' - wider spacing will be engineered on an individual basis. Width between lintels ( also referred to as rafter span ) determines rafter size, widths up to 16' are pre-engineered. Contiuous lengths in 12" and 16" increments are available. Continuos lengths and multiple lintels will allow for a wide range of design possibilites.


Sizes: Sizes are available in 12" and 16" increments. Custom heights are available.

Plan Types: Are indicated in the design reference, under the headings TYPICAL PLAN TYPES WITH ELEVATIONS and COMBINING PLAN TYPES. From the plans indicated, a wide variety of plans may be derived.
