In The Sims 3 Wii game I am unable to purchase/build some of the houses in build mode (e.g. eco house in the misc section) even though I have more than enough money and are using the largest empty block. I buy the empty block, go into build mode, select the house to buy, unfurnished, it appears on the block, I position it then click 'A' to place the house, but it does not work and a building violation comes up when I give up and escape ('B'). I also wanted to know how you place a pool on your block. Hope for help, thanks.
