It's recommended to have at least 6 feet all the way around any Wood Playhouses. That way, your children have plenty of room to run and play without worrying about obstacles. Another factor to consider is playhouse height vs any overhanging trees, powerlines, or other structures. You'll want plenty of clearance so everyone stays safe. Manufacturer's instructions and product specs can give an idea of how much room you need. We carry playhouses requiring space that ranges from 0-10 to 10 - 20 feet high. Check out any local building codes, homeowner association rules, or ordinances to make sure your dream playhouse is ok to put where you want it.
