Rectangular mini pond next to terrace - tips/ideas?

and I have little time..

Next year there will be more as well. Don’t put yourself under pressure. You’ve built a beautiful house, the conservatory, and now the terrace as well. Now just set up the deck chair first and enjoy your work in its current progress. Don’t waste the whole summer on it, it doesn’t have to be perfect in one go.

Thanks, actually you are totally right. But somehow I am still a bit frustrated because last year we accomplished very little due to work and weather. I just wanted to get the area around the terrace somewhat finished this year. :-) I have now spontaneously decided on the PE ready-made pond.
