Is a peat garden with heather and ground covers easy to maintain?

Hello and THANK YOU for your suggestions!

My goal is a garden that is as easy to maintain as possible, but at the same time interesting and beautiful, inviting you to stroll around. Cutting back somewhere once a year is okay. For example, I will not create paved paths, but like it when it looks like a "footpath." Especially in a ground cover garden, I find that extremely appealing.

I am even considering whether to do without a lawn area...

but at the same time a more interesting and beautiful garden that invites you to stroll around

Let's be honest: with ground cover plants, you keep the soil between the planting free of weeds – but you don't achieve a beautiful garden that way.
Plantings only give the garden structure when they are planned with height in mind.
First taller accent trees, then bushes, then beds with perennials and grasses, possibly themed areas, and finally units formed with ground cover plants.

Hello! Thank you for your contribution.

So trees, bushes, grasses, and perennials are definitely imaginable to me as well.

I see the topic of wild gardens like this:
From the very beginning, I want to make it clear through the way I design that my garden is not a rectangular one that tries to please the neighbors, the parents... whoever, and is only kept in a passable condition with great effort, but that it should please only ME. I want to find my own individuality in the garden. I don’t want a garden that is a ball and chain, but one that is fun for me... precisely because it does not have to be mowed twice a week regularly.
I want it to be such that no one can say, "Your lawn needs to be mowed again," but you should be able to see that this garden does NOT WANT to please at all! One should immediately recognize that my garden does not claim to do so.

This has now almost drifted into the philosophical, but I hope you understand what I mean :)

Just wait until your house is built. Then you can start creating your garden.

I want to find my own individuality in the garden. I don't want a garden that is a burden to me, but one that I enjoy..

They all want that ;)

Exactly, just wait for the house... We are getting exactly the same garden - I don't want a golf lawn but a wildflower meadow. Mow twice a year and that's it. Also mostly native shrubs for the hedge. 2 half-raised beds ;) and a stepping stone path. The listed things will be laid out in spring, and then I'll see how much space is in the garden and if/where a tree/bed/stream will go.

Wildflower meadow.... good keyword, but I can already see the neighbors in front of me complaining that some grasses dared to cross the BORDER onto their property.

I think I can plan man-high fences first :D
