This is impossible to answer.The type of ground you propose to build on and nearby trees are just two things that could have a dramatic effect on the depth that YOUR foundation would need to be.

I agree with ROC, there are many factors deciding how deep footings need to be but in normal circumstances 1m deep and 600mm wide.

Building control will make the decision subject to the condition of the soil and other contributing factors that have been pointed out by the previous contractors. This is normally decided when the trench is dug.
