The A structure with open wood-framed roofs, often latticed and supported by regularly spaced posts or columns, and covered by climbing plants such as vines or roses, shading a walk or passageway. Pergolas are distinguished from “arbors,” which are less extensive in extent and structure. in this example is 9m (30ft) long x 2.4m (8ft) wide.
The project is broken into sections (pages) which include working plans, construction details, roof details, and materials. Each section contains it’s own instructions and diagrams etc.
The Any of the framing wood. list is at bottom of this page.

The plans for the lean-to pergola. An example of working plans for a lean-to pergola and roof, 9m (30ft) long x 2.4m (8ft) wide.
Below is an example of working plans for a lean-to pergola and roof, 9m (30ft) long x 2.4m (8ft) wide.
The Site Plan
This plan shows the placement of the pergola in relation to the existing house and boundaries.
The Flat Plan (footprint)
The flat plan is an arial (looking down) view of the pergola addition.
It shows the overall Any of the three linear measurements, length, breadth and depth. of the project and information such as A base (in or on the ground) that will support the structure. placements, A sub-floor wood supporting the floor joists. and Structural member of a roof that supports the roof load and runs from the ridge to the top of the side walls. placement and spacings between rafters.
The Cross-Section Plan
The cross section plan is a plan taken from a cross section of the flat plan. The cross section shows lumber sizes and footing size.
A detail plan is accompanied to give clearer detail.
A detail plan is a blow up (magnified) part of the plan.
The Elevation Plan
The Side view of a building. plan is more like a drawing of the outside of the addition rather than a plan although is still drawn to scale. The elevation plan gives a good perspective of the addition to the untrained eye.
