There was a house that used to be a barn. The last part of it to be renovated was the staircase. What was there was the original barn loft stairs. The homeowner wished to have the bead board removed and shiplap put up.
The staircase was at a very steep angle due to the fact it used to be a barn. We were able to change the angle slightly, trying to accommodate.
We tore down the old bead board and cedar shingles, replacing them with the shiplap.
