PERCH designed improvements to the structural systems of a house in Waterbury Center, VT, to support a new hardwood floor and oak staircase. PERCH worked with the homeowner to support the staircase while minimizing disruption to the floor plan, offering and value-engineering several options. PERCH also strengthened several existing joists that were notched to accommodate utilities like air ducts, developing a plan to install sister joists as easily as possible.
