Can you make your own house on the sims 2 pets for psp?

No,you can not.When you click on an empty lot,you have to choose a layout from the layout screen and there are only 5 layouts,which are floor plans that you can choose from.But all 5 layouts are only 2 room layouts,one room is the bathroom and the other room is the kitchen, and the bed in the same room as the kitchen! But as you progress through the game,you unlock 1 bedroom layouts,then 2 bedroom layouts,then 2 bathroom layouts and so on.
