The centerpiece of an addition to a Montreal house is a new anthracite “iron lace” staircase, which was loosely inspired by wooden circle motifs found in the house’s original entryway. Photo by Andre Doyon.
The back staircase in a Brooklyn brownstone renovated by Jessica Helgerson abuts a glass facade overlooking the backyard and allowing plenty of light into the kitchen area above. The art hanging on the wall is by artist Julie Thevenot. Photo by: Andrew Cammarano
