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

Hello everyone,

we have bought a house on a slope, where the exterior facilities are still missing. From house construction, we know that accessibility on a slope is generally difficult. So conveyor belts and/or a truck-mounted crane will certainly be needed here as well to transport equipment and materials. We are aware of the resulting higher efforts and costs, but we cannot assess the scale.

Based on an initial plan, the following work packages need to be carried out:

- Demolition of the existing staircase up the slope to the house and construction of a new staircase (30 concrete block steps)
- Construction of a gravel area in front of the house, laying 120x120 concrete slabs as a path within it (approx. 50 m²)
- Construction of another staircase behind the house with lateral L-stones (13 concrete block steps)
- Construction of a gravel area around/behind the house, laying 80x80 concrete slabs as a path and terrace area within it (approx. 80 m²)
- Construction of a retaining wall made of basalt palisades on the embankment behind the house (approx. 23 m length, approx. 1 m height)
- Construction of two further staircases to the remaining garden area (each 14 concrete block steps)
- Terrain leveling (smoothing) of the garden area and edging with lawn edging stones (double row, approx. 700 stones)

So far, we have already had several garden landscapers from the region on site for inspection. Most never get back to us afterwards – probably because there is still plenty of other demand with "simpler standard projects." However, we have now received a rough offer amounting to around €190,000 for the above-mentioned work. This amount really shocked us. Is this an exaggerated "I actually don’t want to take the job offer," or are these costs generally realistic/expected in this order of magnitude for the project described here? Perhaps there are also concrete experiences from other/similar exterior facilities on slopes?

Thank you in advance for your assessment!

Hello,

with some own effort, I would also estimate at least 120,000 euros in this region. The paving work alone with such large slabs is extremely expensive, both material and labor time.

Best regards

we bought a house on the hillside,

We’re happy about that - so go ahead and tell us (and don’t forget to show us)!

I would also guess six figures. When I see what main tasks are on your list (all large, high, and numerous) and then think of a slope where certainly enough secondary work is required (foundations, supports, L-stones/deep curbs), the offer you have can also be absolutely realistic.

Show some photos so we can get a feeling for your planning.

Now I can understand why the house was sold.

I would also say more like 190k than 100k when I look at our costs
