This might seem like a fairly ambitious project, but don''t be put off. The biggest concern with an aviary is making the structure bird-proof. Unlike other small buildings you don''t have to worry about making it 100% weather tight.
This aviary is suitable for urban sections, but you will need good access around the building site during construction. The building site also needs to be flat before you start building.
*These lengths allow for 1/3 of the post''s above ground length below ground. The thickness of the post will not affect the plan.
** The quantity of timber does not allow for off cuts. Allow around 5% extra for wastage when ordering.
You will also need sheet iron or a combination of sheet iron and opaque ridged plastic for the roof. Traditional corrugated iron is problematic because of the gaps at each end which small birds could get through.
