What garden fence height would you recommend?

We don’t find hedges visually very appealing and hedges also require quite a lot of maintenance to regularly trim them. We also have to be careful that they don’t grow too much towards the neighbor, otherwise he will complain.

We would rather prefer many different flowers that also provide privacy.

What would you suggest first around the terrace, 160cm or 180cm?

We don't find hedges visually appealing

Accepted.

A hedge also has quite high maintenance because it always needs to be trimmed regularly

Once a year or every two years is high maintenance and too much for you? But the real work with flowers and flowerbeds is your suggestion as an alternative? Flowers do not provide privacy screening (at most dense shrubs, which also need to be trimmed regularly).

Neighbor

Implicitly, your question suggests that you haven't even discussed the enclosure with the neighbor yet? What if you put up 120cm and he then puts up 200cm right next to it because he doesn't like you? I actually know it this way, that you agree together on a fence/boundary and then also pay for it together. That is actually the first step. Otherwise, you must put the fence exclusively on your own property and not on the boundary - if you don't agree.

Yes, we still plan to do that.

We want to first choose a desired height and then ask the neighbor if he agrees with it.

We have already asked if he wants to share the costs and both said yes.

But it is rather the other way around, we don't want to be constantly talked to in the neighbor's garden.

What fence height would you recommend in the terrace area?

We would rather have many different flowers that also provide privacy

There are those too. Look for flower hedges. But they are definitely more work than a beech hedge, especially if you have weeds in the soil. The beech suppresses that.

Do you perhaps mean shrubs? Unfortunately, you won’t get a dense result with flowers alone, I’m afraid. In the garden, you have to cut almost everything, but the hedge actually requires the least work because you simply run the electric hedge trimmer straight along it - done. Shrubs look great, but have to be trimmed individually, so it’s a bit more effort than a uniform hedge.

Unfortunately, you won’t get full privacy with flowers alone, I’m afraid.

It doesn’t have to be 100% opaque, that’s what the privacy strips are for.

Ok, I always thought hedges require a lot of maintenance, but visually we like a uniform hedge less than different flowers.

The most important thing for us is the fence first; everything inside the fence we will plan later.

What height of fence would you recommend near the terrace? 160 or 180 cm?

Is 160 cm enough as a privacy screen?

Is 160 cm the best compromise between privacy and less of a prison look?

140 cm is definitely too low, you can easily see over it.
200 cm is definitely too high.
