Probably nobody here can tell you, and you'll need to get somebody to give you an estimate.

But on the off chance that someboy knows your area, are you talking about steps that are this size (like 10-12 feet wide)? or just his kind of materials, or...?

Both

Many thousands. But no one here knows exactly what you want to do, how large the space is, what is there now, if you need to demolish anything, etc. etc. Your best bet is to contact a stone mason in your area and get a few quotes.

$15k would be my WAG. But that is all it is is a guesstimate.

What do you have now?

I had wide brick steps that they just put concrete pavers from Lowes on top of and it was very inexpensive, no demo, no shipping, no front veneers, no landings. (I needed the existing steps in good shape raised so they didn’t need to take anything off.) I invested about $600 with labor.

The concrete treads and stone you selected would be a lot more expensive, of course, and if you don’t have any masonry steps, they would need to build the foundation. And maybe the two landings. It all adds up.

I was prepared to invest $5000 until I figured out the final solution. Handrails and landings will be DIY and probably run at least another $700. (Top landing doesn’t need much change.)

A quick internet search gave me an average of $2,200 for installing stone steps. You price, of course, will depend on your particular situation. You should be able to find a contractor in your area to give you a price. Also keep in mind that the stair can be solid stone or in can be a cmu (concrete masonry unit, a.k.a. cinder block) backup with a stone veneer. That will affect your cost.

We need to see your house to even begin to guess . So post pics of your house and not just the step area but the whole front of the house . Post here in a comment DO NOT start another post. As for areal estimate you need to find a stone mason in your area.

We redid our walkway and stepsin 2020 with Techno Bloc pavers. The steps were just plain concrete, and they covered them with the pavers on the front and sides and then used a different textured paver for the top of the steps that has a natura edge. They have huge combinations of colors and styles. I don't honestly remember the cost we did some landscaping and also did a brick mailbox at the same time but I would agree with millworkman that you're looking at many thousands of dollars depending on stone and stepsize.

Absolutely beautiful...this is something that I would like to do!

@kelli_ga ....I have wooden stairs right now
