Mr Clues says while the houses would still be structurally sound, consulting a soil engineer would be wise.
"Have them have a look at the type of soil, do some testing and talk to you about different ways of trying to preserve the moisture content in and around the house," he said.
"But what you mustn’t do is suddenly react by soaking areas that traditionally haven’t had water, because you’ll get the same effect of swelling."
Mr Clues says different types of construction materials are also being used to counter the big dry.
"Certainly you’re seeing a lot more different materials and different options in terms of foundations, using steel, treated pine," he said.
"It’s not all traditional masonry work these days, which obviously has a different impact terms of moisture content and level."
