The subject of what do you do with your 5 yard slots it´s something that deserves some thoughts.
My current approach have been two workshops, temple, gazebo and a garden. The gazebo and the temple are obvious choices, the mass actions are something too good to live without them, and the two workshops gives you a workplace for your slaves. Without them they will be idle hands.
The last spot it´s the one that it´s tough to decide. A 3rd workshop would be nice, they give you a lot of money and possibly in a cost-effect analysis possibly would be the best option. I have not a clue what are the effects of a dojo or the stables, but I decide for the gardens simply from a role playing point of view, because I´m almost sure that are the worst investment effective-wise. They are maxed, and I have May Lin as a gardener and I get 38 foot rations per day. Even at 20$ per ration (in my game the food it´s just at 4$), that´s just 760$ per day, and that´s peanuts compared with the net profit that a mid of the road workshop can bring to your house.
But we are in a post apocalyptic world, after all. Things that we give for granted (as going to the market and buy food) are not a sure thing in Raana. And I though that the House of a Proper Gentlemen (capitals intended) must have some degree of self sufficiency, just in case. And also I´m quite sure that the tomatoes the peppers and the eggplants of my garden, cared by the loving hands of May Lin, and harvested just when they are perfectly ripe will taste a lot better that the crap you can buy in the market
