The commercial construction company J.E. Charlotte Construction Corp. last month began the renovation of the exterior facade of Palm Square Plaza in Nokomis. The makeover will include a Key West-style design, with four new tower features at each building corner and reconstruction of an existing walkway canopy. The 28,000-square-foot retail and commercial building is located at 221 S. Tamiami Trail, Nokomis. The project is scheduled to be completed next spring; the stores in the plaza will remain open during the renovation.
