In order to get from our driveway to the front of our house, we have to scale a 3 foot retaining wall. What’s the cheapest way to put a stair in there? We need something safe since this will be the main way we access the house.
The price depends on the material. Using wall stone might be a little more for the cost of material, but thinking long term, if the base is set right, this will last forever.
The cheapest is not always the best way. There are concrete steps, which can be pricey, and there are stone pavers, which are also not inexpensive. I would recommend treated lumber. Done right, they can last 10 to15 years.
