Integrated bird boxes are favoured, as described for bat boxes above. Swift bricks have been shown to be used by a range of small cavity-nesting birds (including declining species) and are strongly encouraged.

In general, bird boxes should be sited on a tree or building facing between north and east, where they will not get too hot. Different bird boxes should be sited at different heights, with most small hole boxes best sited between 2-3m above ground, and swift, swallow and marten nests best sited around 5m above ground. Open fronted boxes should generally have some light vegetation cover nearby to provide protection from predation.

Example integrated boxes:

Opportunities for swallow should be provided where possible, and in all instances where opportunities will be lost (such as barn conversions or renovations). Swallows prefer to nest in sheltered positions so mitigation may include provision in barns, log-sheds, car ports or porches, through providing access to a retained building or through purpose-built structures such as a covered structure at a gable apex.

Owl boxes can also be a fantastic addition where space allows. They should be sited in undisturbed areas, in buildings on or trees, typically at least 5m above ground.

Bug hotels can vary from small pre-fabricated boxes which can be installed on external walls, to large stacks which provide opportunities for a range of wildlife including toads and hedgehogs.

The RSPB have advice here on creating a 'stack' for wildlife.
