Costs of garden landscaping and outdoor facilities at a single-family house on a slope

First of all, it would be interesting to know how much money you actually have ;) That can also be a reason for ghosting. 200,000 EUR is a lot of money for a landscape gardener, he goes far in advance... Just by scaling back from the exquisite material requests to plain concrete, you can save significantly in the five-figure range...

We have the open-pored panels in light gray. They have not gotten too hot in the sun so far. We are very satisfied with the panels.
25k is correct.
Here you can see our planning. And curbstones around the entire house.
I did the planning in 3D and we didn't have any extra panels. That went very well.

We have exactly that in the selection, too. Sounds good that you are satisfied with it :)

I wouldn't immediately assume bad intentions of the garden landscapers who don't respond. Yes, that is bad style, no question.
But as a garden landscaper, you first need to have the appropriate machines and the corresponding experience with a steep wall to be able to implement your wishes.
Another reason might be that garden landscapers simply assume they are writing their offer for the trash can because with prices around 200,000 EUR you won't buy anyway. Over time you develop a sense whether the customer is aware of roughly what his wishes will cost and whether he will be shocked by the offer. Then the work is not worth it.

Have you checked what your 23m basalt palisade in 150-180cm height alone costs? You are easily spending 500 EUR material per meter, so almost 12,000 EUR just for that. Plus foundations, earthworks, drainage, etc.
That is easily 30,000 EUR if done by a professional.

I have been messing around for months with a nearly 1m high garden wall made of concrete paving stones to catch about 50cm height and have already sunk good 5,000 EUR material for almost 30m...

The material alone for your project will break six figures because everything is supposed to be extreme and of course natural stones.

There is certainly some truth to that point. However, this is partly the craftsmen’s own fault (due to quoting astronomical prices). We have already felt that clearly in other trades (3 offers with 3 completely different prices), and the colleague here in the thread wrote something similar about his garden landscaping experiences.

We make it clear to all companies that come by here that we are aware of the additional costs caused by the slope and that we expect costs in the six-figure range. According to my research and previous experiences, however, I land more in a corridor between 120...150k€ – so the 190k€ are already far off. Therefore, I would like to have 1-2 more offers for comparison, but unfortunately so far, as already mentioned, that is not possible because the garden landscapers play dead after the first visit.

Above all, it would be interesting to know how much money you actually have ;)

Just if you downgrade from the exquisite material wishes to plain concrete, you can save significantly in the five-digit range...

The above framework is planned. I wouldn't call our material wishes exquisite (I already wrote that we want to use "simple" concrete block steps and concrete slabs). But I believe (if I understood the previous garden landscaper correctly) that in the 190k€, the big chunk is more the labor/machine costs and less the material costs – so you probably don't make big jumps with the given quantities. But whether that is really the case, I can't currently assess. If you say you can save in the five-digit range, that would of course be very interesting. The look is especially important to us, everything should be as clean/purist as possible. Then I will follow up in this direction again. The only garden landscaper so far rather waved off this inquiry, saying you can’t get much cheaper there.

Well, concrete slabs 120x120 (70, 80kg per slab) or also 80x80, that's pretty exclusive. Plus a good 50 block steps. That's a statement and I don't believe you'll get that for 120,000 EUR. And of course everywhere: gravel, concrete, drainage, moving soil, hauling away soil, etc.

Especially since apparently some have no interest at all in getting involved.

May I know on what basis your estimate of a maximum of 150,000 EUR is based? Have you done any research on what material, excavator hours, etc. cost?

Or is it a "neighbor 5 years ago with similar scope it was only 120,000"?

Keep in mind, what cost 120,000 EUR 5 years ago easily costs 150,000 today.

Before I am misunderstood, another note that I am specifically looking here for experience values for similar landscaping projects on slopes – exactly with the goal of better assessing the currently (only) concrete offer of approx. 190 k€.

My above-mentioned "research and experiences," which bring me to a (vague but only) "expected range" of 120…150 k€, mainly base on invoices from concrete other garden-landscaping projects within family and friends circle. These are temporally similar (new construction projects, 1-3 years ago). Content-wise partially, e.g. regarding the large-format slabs, similar. But in the end still quite different, because not on a slope (hard to estimate what working hours result from the increased logistical effort) and also not in the same region (different companies). As long as I don’t receive other offers, concrete experience values from other slope projects are probably the only thing that would help me further in assessing the 190k€ offer.

Hello,

in the end, it doesn’t matter whether the 190k euros are justified or not. You want to have your garden landscaped. For that, you ask companies. If you have different offers, you can choose. What will you do if the 190k euros seem too much but you have no alternatives? Not renovate the garden?

There aren’t many options. Either do it yourself with the help of temporary workers or award the job at the asked price. If the price doesn’t suit you, then you have to get more offers. Until it fits or you are willing to pay the price.

Best regards

I have no written offers. It was clear from the beginning that the whole thing would be financed from own funds after the house construction. I had talked to acquaintances who have landscaping companies. We are now in the 7th year. Every year, more or less work is done. Your wishes and the scale are one or even two sizes too large for many companies. The new construction of the kindergarten's outdoor area with completely new equipment was cheaper than your facility. Many landscaping companies are well occupied with maintenance work and take care of their existing customers. Have you talked to the companies about how they would do it, or did you specify everything? It seems very labor-intensive to me how you plan it. Just the many stairs alone. The size, the material. I would find a path more practical than a staircase. Wheelbarrows, hand trucks, lawn mowers go up the hill so much better that way. Listen to ideas from "experts." If you’re lucky, a gardener, a mason, etc., will give you their two cents. Call those who didn’t give you offers and ask why. Maybe you’ll get more bidders if you divide the contract into smaller sections? Then it just takes 3 or 4 years. It’s not like it wouldn’t be usable. Much of it is just aesthetics.
