The Scenic Heights Playhouse is made from 100% cedar. With small, tight knot structure, your lumber will be less likely to develop small cracks emanating from knots. In laboratory testing, our durable cedar wood proved to be rot resistant and highly resistant to natural decay. All lumber is pre-stained for a smooth and clear appearance, as well as cut and stamped with the part number to help speed up the building process. Some pilot-hole drilling may be required. Our exclusive Safe-T-Fuse hardware makes assembly easy and secure. Assembly requires two moderately skilled people 18-24 hours.
