All about How to make a nest box

Equipment needed:

  •  A plank of wood:
  • 160cm long, 140mm wide, 15mm-20mm thick.
  • 1.5” Nails - suitable for being outdoors
  • Sandpaper
  • Roofing felt or bicycle tyre inner tube for hinge
  • Tacks for fixing hinge
  • Drill bits - For next box entrance and also possibly for pilot holes
  • Timber saw
  • Workbench
  • Pencil
  • Tape measure
  • Hammer
  • Small piece of wire


Measure your plank to the lengths shown in the diagram above.
Draw in the pencil lines from edge to edge
IMPORTANT BIT! Turn the plank on its side towards you and measure the bevel line shown in the diagram below.   This will give you a slanted edge between
the top and the front on the finished box


With the plank still on its side, saw the slanted cut first.  Then turn the plank back so it is flat and continue with the other cuts


Sand any rough edges on the cut pieces


Using 1.5” nails, attach the base to the back panel, positioning it onto the back rather than underneath it Now, using the same nails, add on the side panels positioning them on top of the base.   Now add on the front panel so that there is a continuous slant down from the attached side panels. Cut a piece of roofing felt and attach the top section to the back section like a hinge using clout nails Affix predator protection mechanism using clout nails and wire.


Choose what size hole you want and bore it out on the front panel.  Drill a smaller hole towards the top of the back for the nail to hang to the tree, and some drainage holes in the bottom of the box to let any water run out.
