I have seen some underbuilds turned into beautiful living spaces however, one was a large garage that had a 'sump' under the floor, it was to catch rainwater coming under the door, there a pump with a float switch and worked well. But damp was a constant issue. Using a borrowed meter that probed the wall I found one wall was very damp. The owners dug out the gravel that was between the outer wall and pathway, this was around three feet wide, the plan was to waterproof the outside wall, this was to stop the irrigation watered soil laying against the wall. Getting down around a meter they found various building rubbish, the usual stuff, bricks, mortar, a couple of Tesco carrier bags (yeh I know), but of more importance multiple huge bags that you see wrapped around stacks of new bricks! They acted as a water barrier preventing water from draining away, they dug down to the footings and drowned the exposed walls with a water deposit paint. Leaving the garage door open at every opportunity, the wall dried out and there were no more problems.
Next up was another huge underbuild, and in fact was a house I was going to purchase, thankfully my wife and I found it would stretch our finances a little too much so we passed it by. I got to know the people that did purchase it and regularly serviced their car. They added two bedrooms, bathroom and even a man cave, no expense was spared, they had lived there for around ten years when the first 'Gota Frier' hit them, this overwhelmed the drains at the garage door, and they even had water coming up through the toilet and sink. Beds and various pieces of furniture were literally floating, insurance did NOT cover them as it is was not considered as a living area!
Think seriously before laying down your hard earned cash.
