Natural stone walls are a symbol of naturalness and value retention. Our calculation example should help you to estimate the costs of a natural stone wall correctly.
Natural stone wall types in the overview
Natural stone walls are built in four different, basic types:
- As a leaning wall on a slope or raised bed etc. in dry installation
- as a leaning wall on a slope or raised bed etc. with solid masonry
- as a free-standing wall with solid masonry or as
- free-standing wall in dry installation
the latter is, however, in view of the high weight of the material of static concern and applicable only for low natural stone walls. Natural stone walls in dry laying have the advantage that they can be made particularly natural by integrated plantings. Hard-walled natural stone walls, on the other hand, ensure a high level of stability and, with appropriate design, are an effective protection against slipping soil.
Cost calculation using the example
The biggest cost factor is the natural stones. But here too there are differences. Of course, boulders are more expensive than quarry stones and the type of rock determines the price.
The calculation example is a free-standing natural stone wall with carved limestones, average edge dimensions 10x10x25cm, and one meter wall height. At five meters in length there is a wall surface of 2x5qm = 10sqm.
- 10 square meters of hewn limestone = 950.00 €
- backfill of coarse gravel 1.5 cubic meters = 60.00 €
- precast concrete 2.5 cubic meters = 175.00 €
- material transports flat rate = 150.00 €
- excavator rental 1 day = € 100.00
- Dredge rental 1 day alternatively with equipment guide = € 320.00
- In own effort, such a wall of five meters in length costs: around € 1,450.00
- In-house, but with the equipment guide: around € 1,670.00
Unheatened and hewn natural stones are not only found in the natural stone trade, but also directly from the quarry. However, it is not calculated in square meters, but in tonnes. If you want to be sure and do not want to buy too much or too little (two transports will also cost you twice the cost of transport), you should convert the square meters into tons.

How to convert the square meters into tons (example)
- In the example mentioned, the average edge dimension of the carved limestones was 10x10x25cm.
- With a wall height of 1m you need 4 × 10 = 40 stones per square meter.
- The length of the wall is 5m, so 5 × 40 = 200 stones.
- Since you have two visible surfaces in a freestanding wall, you have to count twice. You need a total of 400 stones.
- Weigh an average sized stone and multiply that weight by 400 and you get the total weight in kilograms, divided by 1,000 = tonnes.
For unhardened stones, the calculation is the same, but with an average sized stone.
Specialist company or own contribution?
The construction of such a natural stone wall is associated with great effort and knowledge from the masonry industry. Errors, especially with a non-binding joint offset, lead to a poor result with considerable investment.
Gardening and landscaping companies
If you can not do this work yourself, you can also hire a specialist company. Contact persons for this are above all the companies from the gardening and landscaping. But also some road construction companies have opened up this task area. Ein Get tips from the neighborhood
Certainly, the yellow pages are suitable to find such a company in the vicinity. However, it is better if you look at natural stone walls in your neighborhood or nearer. Here are many tips on recommended companies. Get from these companies about three offers and you will find your favorite specialist company, which is pleased about your order. Based on the previous calculation example, the total cost is approximately € 2,700.00.
How to save costs
Like everywhere, DIY stores are not always the cheapest suppliers.
Directly from the quarry
If you want to achieve a savings effect, you can also contact a quarrying company directly or refer to used basalt paving from a road construction company. Although you will not get your stone material sorted out so thoroughly here, but with clever workmanship with a visually interesting joint offset you will achieve an equally high-quality result.
Cheap rock types
The choice of rock determines the price. Granite is more expensive than quartzite and hewn stones are more expensive than quarry stones. From all these materials, however, successful natural stone walls can be erected.
What you should consider during construction
The most important rule is that natural stone walls from a height of two meters require a static calculation and building permit. With regard to all other aspects, the regulations are regulated differently in the state building regulations of the respective federal state. Especially in terms of distance to the neighbors, it is always cheaper to ask the building office.
A natural stone wall is in any case a worthwhile purchase. It can demarcate, support, integrate into a planting or dominate as solid masonry. It is always a cost-intensive but long-term sensible investment.
