Lining the house
This is the original metric version of the plan (millimetres/centimetres). See also Rabbit hutch plans : Imperial (feet/inches).
The pieces in figure 6.1 need to be cut from 7mm plywood. Make two copies of the piece in the middle, one for each side of the house.
The larger rectangle goes on the side of the house closest to the cage. But attach it 25mm from the top edge so that you can attach the roof hinges later. The rest of the plywood cut-outs should completely cover the house as shown in figure 6.2.
30mm flat head nails are ideal for attaching plywood, and we recommend you use adhesive around the edges as well.
