Stefan sent me a note and said we were only a few weeks away from setting our spot in their production line for our originally-planned early June delivery. Given the delays in getting permission from Värmdö, that's really just too soon.
I spoke to our Janne, and also Janne W the builder; we've decided to go for construction on week 32 instead. That would mean delivery to the dock on Tuesday, August 5. This should give us plenty of time to get the full building permissions, complete the foundations, and be ready to go.
