Its quite easy to isolate a house battery from the starter battery. For example, my car has a cigarette lighter adapter in the trunk. It only runs when the car is on. You could also use a relay to do this; closing the relay when the car is on. Or when a switch is actuated. Blue Sea has a nice automatic battery isolator.
However there is another issue to consider. Mixing the chemistry of the batteries you want to charge can cause issues (mostly it abuses the batteries and they don't last as long.)
