The invention comprises a system for constructing a finished convex or concave curved wall of any desired radius beyond a specified minimum. The wall is constructed of pre-finished rectangular panels retained on a sub-wall structure in horizontal rows and vertical columns. The panels are retained on the sub-wall structure with vertical rails at their vertical edges and retainer clips spaced along their horizontal edges. The panels are slotted at their rear face to provide rigidity in the vertical direction and flexibility in the horizontal direction. The horizontal edges of the panels are kerfed to receive the retainer clips and flexible splice strips that conform to the curvature of the wall and align and space a panel with the panel immediately above it. Clips attaching vertical edges of the panels to the rails allow the associated areas of the panels to align tangentially with the curvature of the wall.
