Hello philhumphrey ! I have uploaded your file with some modifications. You have to play with density on the house and the buoyant material. and look how joint connection tool works or better you have to play a little with MSPhysics to understand how it works.For this you can download some file on 3dwarehouse searching "MSPhysics".
