A picket fence is perfect for framing a driveway and isn't difficult to build.
Fences are a great way to spruce up your home and define your property. Whether you want privacy or simply a decorative touch, a fence may be what you are looking for. Learn how to build a beautiful picket fence.

* Note: These instructions are for a fence that lines the perimeter between a curved driveway and flower garden.

Materials:

pressure-treated 4x4 posts
tape measure
pencil
post-hole digger
crushed stone or gravel
circular saw
quick-setting concrete
water
4-foot level
pre-cut pickets
2x4 rails
drill
2-1/2 inch galvanized screws (have plenty on hand)
hinges
ratchet
cane bolt and gate latch hardware

Steps:

1. Because of the curve of the driveway, 4x4 posts will be installed every four feet on center. This will help make the curve while the fence is as close to the driveway as possible. Along straight sections, posts can be placed six feet on center. Mark the locations of the posts on the concrete with a pencil (figure A).

2. Dig your post holes (figure B). The size of the holes you'll dig are determined by the height and weight of the fence and the depth of the frost line in your area. Basically the holes should be about two to three times the width of your post and set deeper than the frost line to prevent "heaving."

3. Once your holes are dug, pour a two-inch bed of crushed gravel into each hole. This will help drainage. Next, cut the posts to length and begin placing them in the holes. Using the post, tamp the gravel down and begin adding quick-setting concrete and water around the post (figure C).

4. With a level, check the posts for plumb as you tamp down the concrete to remove air pockets. When pouring concrete, pour one to two inches above ground level and slope it away from the posts to divert water (figure D). Come back about 20 minutes later and check to make sure the posts haven't shifted. Allow concrete to cure. * Note: Be sure to measure each post from the ground up to ensure that each is the same height. If a post is too high, you can top it off with a circular saw.

5. Begin attaching the rails to the 4x4 posts. Cut to length, then pre-drill screw holes. Attach rails to posts with 2-1/2" galvanized screws (figure E). Two rails are needed for each area between two posts. One rail will align flush with the top of the post. The bottom rail will lie approximately one 2x4 rail-width from the ground (you can use a 2x4 on its side to lie the rail on as a guide).

6. Begin attaching the pickets by first placing one picket over each 4x4 post. First, make sure that each picket is plumb, then secure with galvanized screws (figure F). Next, take measurements and make calculations for the remaining pickets. Use two two-inch-wide spacer blocks to space each picket (figure G). Attach all pickets.

7. Next, you'll need a frame for the gate; in this case, it is a double gate. Cut 2x4s to length and temporarily screw them into place between two posts. Attach uprights for the frame, then diagonal cross-braces to form the gate frame (figure H).

8. Attach the pickets to the gate frame next. Attach sturdy metal hinges to the frame from each opposite 4x4 post (figure I) with the lag screws provided by the hinge manufacturer. Once all four hinges are in place, attach a cane bolt to keep one end of the frame in place (figure J).

9. To separate the gate, use a circular saw to make cuts flush to each side of the two center pickets. Once these cuts are made, attach the latch and the project is complete (figure K). This project costs in the neighborhood of $300 and takes two days to complete.
