Ok, just a couple of days after ground preparation works started first problems appeared. Contractor called and told that the rock is going to be in the way of the house and if I want to keep given heights, we need to blow it up. Blowing up rocks is quite typical for construction projects in Finland, but it is expensive.

Calling a meeting with a contractor and project engineer on the spot to decide what to do next. After two hours of measuring and remeasuring, double-checking the blueprints and considering various option the decision is made – ground will be raised by 20cm, house will be moved away from the stone. Construction inspector came to the construction site as well and after reviewing proposed changes gave final approval.
