Perfect Treehouse
For kids, building a tree house can become an obsession. A private place to call their own, a high perch from which to watch the world, who can blame them?
Obviously, building a tree house is no small task--it must be done right for safety sake, and so you don't create an eyesore in your backyard. Hint: If you don't have much building experience, find a friend or family member who is handy, and willing to lend a weekend of his or her time. And then you must have a good stout tree with branches that spread in a V-shape, and is located away from power lines, the street, and other potential dangers.
Before you start on a design, go to a building supply
store to find out how much all of the materials will cost.
Listed below are the materials needed and the estimated cost
that we came up with (prices vary according to location and
store).

| Seasons: Spring | |
| Materials: wood | |
| Instructions: | |
| 1. | 
Frame:
To begin, measure the rectangular frame for the tree house floor. If you get through this, you'll get through the rest. This is the hardest and most tedious part, and no one will enjoy it. Lay a 2' x 6' on the ground next to the trunk beneath the two limbs that spread into a V. The boughs rising through the floor will become, on one side, a natural railing and on the other, a living stool. Our tree house floor is a 5' x 6' rectangle. That leaves about 14' above ground--11' to the tree house floor plus 3' extra to become the corner posts for a railing. |
| 2. |
Four Corners:
Fasten a 2' x 6' to the tree with two 6" lag screws. |
| 3. | Drop a plumb line from each end; mark where it falls with sticks |
| 4. | Using a square, measure the length of your floor from each stick and mark those spots |
| 5. | Use a posthole digger to dig two 2 1/2' deep holes. Pour 6
inches of concrete into each hole; let set 24 hours.
|
| 6. | Place 4' x 4' posts in holes; pack with dirt.
|
| 7. | For the frame, complete the rectangle by nailing the three
2' x 6' boards to the ends of the original 2' x 6', and to the
outsides of the 4' x 4' posts.
|
| 8. | 
Diagonal Support:
Cut wedges in the ends of the two 2' x 4's. |
| 9. | Nail one end to the underside of the frame, the other to the bottom of the posts. |
| 10. | 
Floor:
Run 2' x 6' floor joists 16 inches apart and parallel to the original 2' x 6' board. Nail from outside the frame |
| 11. | Cut the floorboards to length and lay them perpendicular to the joists. |
| 12. | Cut notches in the end planks to fit around the posts and all four rail supports. |
| 13. | If desired, cut curves in the floorboards to allow tree
limbs to come through.
|
| 14. | 
The Ladder:
Cut two 2' x 4's to match the height of the 4' x 4' posts. Space 16 inches apart. |
| 15. |  Place on bricks in the ground so the ladder won't sink, fit
the top into notches you've made for it in floor, and nail it in.
The top will poke through the floor and serve as railing
supports |
| 16. | Attach 2' x 4' rungs all the way up, leaving 12 inches between the tops of each |
| 17. | 
The Railing:
Double up two 2' x 4's and run them through the notch you made in the final floorboard. The post should match the height of the 4' x 4' columns and ladder. |
| 18. | Lay 2'x 8's over the four corner railing supports. |
| 19. | Cut at a diagonal so each pair of sides meets to form a
squared corner.
|
| 20. | Nail balusters 6 inches apart to the outside of the floor frame and screw each to the top railing |
| 21. | 
The Roof:
Attach vertical 2' x 2's to each corner. Join with four horizontal 2' x 2's to make a rectangular frame |
| 22. | Screw two other 2' x 2's at an angle to form a gable at each end and add a vertical support at the two center po |
| 23. | Join the gables by laying a 2' x 2' between them |
| 24. | Drape the frame with a tarp and staple down. |
