Build a basic and cheap fort for your backyard.
These instructions are a guide to build a 6×6 fort that is roughly ten feet tall. It has a ladder leading into the Deck area. The Deck is four feet from the ground and the roof is four feet from the deck.
It has an option for a sandbox at the bottom.
Cost: The price for the materials to build this project would be dependent upon what material that you purchase. Some lumber is more expensive than others. However, the original structure was created with standard pine so the general cost would be around $200, which would include hardware.
Time: I am not going to waste your time to estimate how long it will take you to assemble this fort. Every person has a different speed and it depends on your tools and expertise, obviously. As well as how much free time that is available to you.
Theoretically, it could be completed in one day. Also theoretically, it could take you a week. If you hire some of the contractors that I’ve heard complained about, it could take them a whole year.
