Redwood has a warm, natural beauty that fits well with residential architecture, complimenting your home and landscape. Redwood and cedar are both naturally resistant to deterioration (specifically the top quality, All Clear Heart Redwood & Finest A Grade Cedar we use).

Heart redwood material, the truely red part, is the only part of the Redwood which is rot resistant and no one but Sturdi-built makes heart grade redwood greenhouse kits.
