Floor plan design for a hillside house with 5 children's rooms

We are now trying to design the garden without L stones after all. With enough terrain, that should work.

Tell me, we are selling our old house next week. What move-in date for the new house do you consider realistic? Unfortunately, the construction manager refuses to comment on that as a matter of principle.
Tomorrow is the acceptance of the sanitary rough installation; the electrical work is finished. The windows should be repaired by tomorrow. Then, according to the plan, the plaster should be applied next. The drywall installer will probably do the painting for us, and we will also have the floors installed. The floors will be laid by an acquaintance who is flexible with timing.
Do you think moving in by 11/15/2018 is too optimistic??

For us, it was 10 weeks after screed drying.
Does the acquaintance do the floors only on weekends and after work with your help, or can he work full days?

I think November 15th is realistic. Your site manager should be able to say something. She doesn’t have to say the acceptance is on October 25th, it’s enough if she says you can start with the floors in early October or something like that.

Don’t make the slope too steep. Take a look at what the usual lawn mowers can handle.
Why not integrate a slide into the slope and have the big sandbox at the bottom?

The acquaintance does this as a full-time job and during the week. We support on weekends. Yes, we also want to have slope sliding [emoji7]. Luckily, we have space at the back so that the inclines don't have to be so steep. We will now fill the entire rear side of the house and protect the bathroom with a light well. In between, we thought we would only fill up to the bottom edge of the upper floor at the terrace and leave the bathroom window free next to it. But then you have to catch so much with L stones and have less flat area. Therefore, we now want to do it differently.

Realistic, but would find a buffer of one month for both, so December 15th, not bad.

We are allowed to continue renting in the old house in any case. A rental period of 3 months if needed was agreed upon. That would then be until sometime in February 2019
