Affordable garden in new construction - how to proceed best?

Did you get that from the landscape gardener’s catalog? ;)
Where do you think you wouldn’t be able to achieve that quality? You just have to do a bit of research beforehand, but most of it is no rocket science. I would definitely leave it to a professional only for retaining walls well over 1m. Drainage strips, paving, lawn, fence – all of that can be done well by amateurs. Since you now live directly on site, you can also do a lot bit by bit.

Yes, that statement could actually come from the landscape gardener ;) But jobs like that are not called apprenticeships for nothing. I also don’t wallpaper or paint myself, because I just don’t have a knack for it. There are definitely things I will have done by someone else. I once built a fence (including concreting the posts) with a friend, but the wire mesh panels didn’t fit properly :oops: And paving sounds easy at first, but since you have to consider a slope of 2–3 degrees on the terrace (and that already in the substructure), I’m unfortunately out on that. With lawn/flowers etc., you can also make a lot of mistakes, but those are easy to fix. Wrong spacing or slight tilting of concreted fence posts, on the other hand, are not.

And I didn’t want to step on any gardener’s toes, but for me, the garden (or the rear outdoor area as you so fittingly call it in my case) is simply an area that somehow needs to be cultivated or prepared. And whether there are plants, shrubs, hedges or not is really up to everyone themselves.

Please don’t, I always find your tips very helpful and also benefit from this thread because our garden area is also due at the latest next year.

… gladly in the garden thread. But not in the plastic thread ;)

And whether there are plants, bushes, hedges or not is actually up to each individual.

Wrong. See #24. I would actually be interested to know if your development plan says anything about it. Have you ever looked into it?

And laying pavement sounds easy only at first, but since you have to consider a slope of 2-3 degrees for the terrace, for example (and that already in the substructure), I'm unfortunately out of that.

That's quite simple. You take a long straightedge and place it on the substructure so that it rests everywhere. Then you take a spirit level with two vials (one 0 degrees, one 2 degrees) and if the 2-degree vial is level, everything fits. Otherwise, rework with the shovel. And if you end up at 1.5 or 2.5 degrees, that's not the end of the world either.

And I didn’t want to step on any gardener’s toes, but for me the garden (or the rear outdoor area as you aptly call it in my case) is simply an area that somehow has to be maintained or arranged

You can make life easy or hard there. The perfect golf lawn needs mowing every week (well, for that there are robots) and the perfectly trimmed hedge takes just as much work as the styled flower beds. A slightly overgrown garden requires much less work and is at the same time animal-friendly. If you have many birds in the hedges, pests in the vegetable garden are also less of a problem ;)

I grant everyone what they like. But bringing unnecessary plastic products into nature, sometimes the raised finger has to come out: You are also off on the wrong foot with many assumptions and opinions:
Meadow/lawn
Expensive/cheap
Privacy screen/fence
Seed/roll turf
So, you really hit the wrong assumptions hard with your thread here - that's okay: after all, a forum is there to inform.
But then it's also up to you to read carefully:

Not everyone wants a maintenance-intensive garden with plants, shrubs, etc.

By the way, a lawn is the most maintenance-intensive thing a garden can offer.

Just a shame that apparently you are immediately attacked for having a minority opinion.

You did not get any attack from me, but the information (among others) about the environmental outrage. It is up to you to think about it.

I don't wallpaper and paint myself either

Ok, then at the end of the day only lawn mowing remains. (Not even sowing) Then you have to have a landscape gardener come and draw up a plan. Warning! costs money! Then get 2, 3, 4 requests and offers. But the topic is certainly already settled in 2022. Execution spring 2023.
