About Us

CornerStone is a full-service Interior Design firm located in Lewiston, ID serving the Lewis Clark Valley and surrounding areas. Since opening its doors in 1995, Jeanine Bennett-Swan has spent the last almost three-decades curating a team of the best architects, contractors, carpenters, stone and surface fabricators in our area.  With the help of this team of professionals, our designers provide space planning, color, and product selections for both commercial and residential projects. Our designs and product choices are not only beautiful but comfortable, practical, functional, and meticulously planned.

We work on all types of projects including multi-family home projects, commercial spaces, single family homes, condos and even bungalows. Our design team can create amazing spaces with budgets of any size. We watch our client’s bottom line closely, and in return have been rewarded with repeat customers who recommend us to their friends and families.
