Cost of filling the land

Hi,

can someone roughly tell me how much it costs to raise a plot of land to street level!? Our plot slopes down in the middle and we would like it to be level. I estimate it's about 50-80cm. Plot size about 700 sqm. Hard to say how many tons are needed, as we don't know the exact slope of the plot. That's why a rough estimate would be sufficient for me.

Well, you should be able to roughly calculate the cubic meters. Length*Width*Height. I'll estimate 50cm for half of your property. That would be 350m³.
Cubic meter of screened topsoil costs about 10-15€. If you don't necessarily need screened soil, then check classifieds, ask at construction sites, etc.
The most expensive part is the transport costs. If a 4-axle truck can be used for the trip, then calculate about 70€ per trip. About 18m³ of topsoil fit on one truck. So roughly 20 trips.
Trips = 1500€
Screened topsoil = 4000€
Then you just need someone to spread it all. I would have rented a wheel loader for a week and done it myself. So another 1000€.
There is potential to save, of course, if you find someone who wants to get rid of topsoil. You could share the trip costs and the topsoil is usually free.
