Overview

This is an Example plan, has not been validated

One cedar fence picket becomes a house that wrens and chickadees will actually use. A perfect project to build with a kid: seven pieces, one afternoon, real wildlife payoff.

The details that matter to birds are the hole size (1 1/8" for wrens, 1 1/4" for chickadees — bigger invites sparrows), ventilation, drainage, and no perch (perches help predators, not songbirds).

Hardware & consumables

Lumber & sheet goods

Tools

  • Jigsaw Also works: Band saw, Circular saw, Miter saw
  • Drill — Plus a 1 1/8" spade or Forstner bit for the entry hole

Everyday tools (hammer, tape measure, square) are assumed.

Build steps

  1. 1

    Cut the pieces

    Step 1 of 5

    From one picket:

    • Front and back: 9" long, with a peak cut at 45° on one end of each
    • 2 sides at 6"
    • Floor at 4 1/4"
    • 2 roof pieces: 7" and 6 3/8" (one overlaps the other at the ridge)
    Cut the pieces
  2. 2

    Drill the entry hole

    Step 2 of 5

    Bore the entry hole in the front piece, centered, about 6 1/2" up from the bottom: 1 1/8" for wrens, 1 1/4" for chickadees. Resist the urge to add a perch — the birds don't want one.

    Drill the entry hole
  3. 3

    Assemble the box

    Step 3 of 5

    Glue and nail the sides between the front and back, then fit the floor recessed 1/4" up from the bottom edges (keeps rain from wicking in). Snip the floor's corners off first — instant drainage holes.

    Assemble the box
  4. 4

    Add the roof

    Step 4 of 5

    Nail on the two roof pieces with the longer one overlapping the shorter at the peak. If you want to clean the box out each spring (the birds appreciate it), hinge one roof half instead of nailing it.

    Add the roof
  5. 5

    Vent and hang

    Step 5 of 5

    Drill two 1/4" vent holes high in each side under the roof overhang. Leave cedar unfinished — paint and birds don't mix. Hang it 5–10 feet up, away from feeders, hole facing away from prevailing weather. Then be patient: houses often get tenants in their second season.

    Vent and hang
