Lesson 1Structural systems and materials: timber frame, steel portal frame, masonry infill, and economical combinationsThis section compares timber, steel, and masonry structural systems for small barns. It explains spans, post spacing, bracing, and how to combine materials to reduce cost while keeping the building durable and easy to build.

It explains collection points, gravity flow options, and siting storage to protect water, reduce odour, and allow future expansion.

It covers cross-ventilation, ridge vents, sidewall openings, and translucent panels to control heat, humidity, and interior light levels.

It explains overhangs, gutters, downspouts, and simple ridge vents that protect walls, yards, and interior spaces.

It covers feeding alleys, resting areas, bunk and trough design, bedding choices, and drainage that keeps lying areas dry and reduces hoof problems.

It addresses frost protection, drainage slopes, and durable, non-slip finishes for cow safety.

It covers cow flow, hygiene, equipment placement, and planning milking alleys for safe, calm routines.

It considers sun path, prevailing winds, distance from the house and manure storage, and access routes for feed, milk pickup, and emergency vehicles.

It covers safe circulation, non-slip walking surfaces, lighting, and simple handling gates and restraint points that reduce strain and injury risk.
Safe worker paths and cow–human separationNon-slip walkways, steps, and thresholdsLighting levels for milking and night checksErgonomic placement of tools and outletsHandling gates and basic restraint pointsLesson 10Sizing and spatial planning: cow numbers, stocking density, stall or loose housing space calculationsThis section explains how to size a 20-cow barn, calculate stall or loose housing space, and set stocking density. It links cow comfort, manure alleys, and feed space to daily routines and future herd growth.
