Hey Martin,
progress! I Cant wait to see you and your wife enjoying it...

I wanted to try to give some inspiration. What kind of flooring? If you could start to consider something like Bamboo, you could attempt a design that leaves the entrance area of the floor with a variable support. Without an initial entrance support, the overhang floor slating would be flexible enough to ramp the 90 mm.... You could then have either a manual shoring truss, or even create something that is variable with a lever, for when you have guests that need to step there.....

Anyway, that's all I have... The pavers look nice by the way...
