Parents, teachers, and administrators alike are delighted that arriving pre-schoolers can stay comfortable even on rainy mornings under the solid roof covering of an impressive expanse of pergola. Substantial supporting columns atop stone bases add to the pleasing architectural design. For generations, Walpole has worked with builders, developers, and architects to create custom outdoor structures to exacting specifications and style demands. Today, our custom pergolas are handcrafted in low maintenance, long-wearing cellular PVC.
