Affordable garden in new construction - how to proceed best?

Hmm, Katja has already revealed so much about herself here in the forum, you could visit her with a little bit of detective work.

You see it differently, that single-family houses are not per se a sensible use of space when it comes to creating living space? What is there to see differently, that is a no brainer.

The solution is not skyscrapers but condoms.

240 sqm is not much. A rigid high privacy screen (check how high it is allowed to be) quickly creates a feeling of confinement, backyard. We had the same consideration years ago. However, more naturally vertical gardening.

You wouldn't be the first to catch the garden virus. I have a brown thumb indoors; even artificial flowers die on me. Outside, almost everything succeeds. 240 sqm is not much. A rigid tall privacy screen (check how tall it is allowed to be) quickly creates a feeling of confinement, like a backyard. The idea was considered years ago in our case too. However, more naturally vertical gardening. If a play area and the obligatory 3 strawberry plants are to be accommodated next to the terrace, not much is left. And check if there really are no regulations regarding planting. Many development plans seem to only allow you to choose the tulip color. By the way, bulb flowers are an example of how little work plants require. Bury them once, and the rest happens on its own.

My father has a semi-detached house in Hamburg with a 235 sqm plot. A small but nice front garden with lots of greenery and shapes, a terrace at the back, a little bit of lawn, flower beds, hedges, solitary bushes to break the view, columnar fruit trees, raised beds on the house wall for tomatoes, cucumbers, peppers, strawberries, etc. In addition, a garden shed with a summer kitchen and a carport with a garden shed. It feels like being on a 500 sqm plot.
...around the corner to the left is the strip with raised beds and columnar little trees.

I assume that the bushes at the very back belong to the neighbors and are simply "shared" when it comes to making the garden look bigger? ;) And even if it’s not the case here: in our 150 sqm terraced house garden, I had (far) views of the neighbors' planting and thus had a visually huge garden… but that doesn’t work so well with privacy fences. Everyone had privacy through bushes of reasonable size or where you need privacy, namely _at_ the terrace, not 10 meters away from it. Then privacy is also wind protection.
