As I thought, he didn't go out this week, the weather has been very poor (as I write this, it's 2°C and raining hard). Working outside in the cold rain isn't very fun or safe.
However, high pressure and sun is due in on the weekend so he is planning to come out Monday. He's going to talk to Jonny, whose company sent us the expert kitchen assembler Johan in October. Jonny's guys are going to do our bathroom and Wille will see if he can send someone to start next week when he's there. Our plan is to complete the bathroom when we're there in April, but a head start won't hurt.
