Big Backyard Fort Plan

Take cover men, the enemy is right at our doorstep!  When it comes time for young siblings and friends to set aside their affable demeanor and choose opposing sides all in the name of fun, there's a good chance someone has built them the Big Backyard Fort Playset.  Packed with loads of ways to climb, hide and interact with, this big 16x21 play fort will make for a fun and exciting skirmish into imaginative play.

A Medieval remix of our Twin Peaks playset, the four main towers, each with a trap door to a dungeon... or lower area, are interconnect with four bridges that group them all together. In addition to having four trap doors, there are also six ramps, two that lead to the center and four that exit out.  Mock battlements can also be found on the towers and two of the bridges, adding a greater castle ascetic.

Designed with children ages 2-8, the Big Backyard Fort Plan is guaranteed to make for a lively and thrilling outdoor adventure!  Be sure to also look out the younger brother, the Fun Fortress Play-set Plan too.
