I think it's a beautiful book, quite well designed for explanations construction (if you are already a minimum handyman anyway!). As against the necessary budget ... !!? I built the first of 12 small poultry houses for 2 hens. A good third of the materials was the Recycling and yet I had to almost 200 euros, comparing prices, and ultimately at a discount! In the book, it's 100 euros planned! Low-end paneling (about 4 euros / m2) are of poor quality, I preferred the lot above, slightly more expensive but much better bill and French, NF, with forest protection ... etc ... The thick water-repellent chipboard, marine plywood or outdoor wood figure ... fast! To sum you can acquire this book but do not over rely on costs given for each accomplishment.
