The plan: foundations, low wall, posts, frame, roof, overhang, curtains
A plan is not a drawing to look nice: it is the list of everything that must be built, with its measurements, in the order in which it is built. Whoever can read a plan can check the mason; whoever can make one can order the right quantities and refuse the quote that does not match. This lesson describes, element by element and with the dimensions, the 8 × 40 m house we have sized: from the footings under the posts to the curtains, through the low wall, the frame, the roof and its overhang. No drawing here: words, figures and quantities.

- ✓Read the three views of a poultry house plan (plan view, cross-section, elevation) and find every dimension on them
- ✓Describe each element of the 8 × 40 m house with its dimensions: foundations, slab, low wall, posts, trusses, purlins, roof, overhang, wire mesh, curtains, doors
- ✓Calculate the main quantities: number of posts and trusses, m³ of concrete, blocks, m² of sheeting, mesh and curtain cloth
- ✓Spot on a quote the element that is missing or the dimension that has changed
- Reading a plan: three views and a scale
- Foundations and slab: what carries and what drains
- The low wall and the posts: the structure that stands up
- The frame, the roof and the overhang
- Mesh, curtains, doors and lobby: closing without suffocating
- The summary: the plan on one page
