Think about it carefully, edges are better for mowing the lawn because you can drive over them. With raised edges, you always have the problem that some grass remains standing, which you then have to cut by hand.
Why did you choose different paving stones for the area around the house than for the terrace? I would have done it uniformly. But you surely had a reason for that, right?
Yes, the reason was the money. ;)
We also paved in front of the house and under the carport and shed. The entire area in front of and around the house is well over 100 m². The plain concrete rectangular stones were significantly cheaper there. For the terrace, however, those were too plain for us, so we took tumbled stones for that. They are still made of concrete but look nicely rustic. They also match pretty well in color with the simple ones around the house.
The thing about mowing the lawn is a very good argument. I always found it annoying along fences before.
I was thinking of something like this for the edging:

Maybe a bit higher towards the flower bed – if that doesn’t use too many stones – but definitely with a mowing edge on the lawn side.
Today I want to start with the garden layout. It will be exciting; I am a complete beginner and have never done anything like this. We took over the garden at the rental house in jungle condition. O.O
But so far, luck has been on my side; yesterday I got a bargain and acquired a pallet of clinker bricks very cheaply. :eek:
