BS 42021 discusses integral nest boxes. The aim of the BS 42021 is to provide best industry requirements for integral nest boxes.
BS 42021 specifies requirements for the selection and installation of integral nest boxes in buildings within new developments, including traditional, modular and modern methods of construction intended for new build developments for residential, commercial, industrial and public building, renovation and refurbishment
BS 42021 covers the design and installation of integral nest boxes associated, principally, with the following bird species: swift (Apus apus), starling (Sturnus vulgaris), great tit (Parus major), blue tit (Cyanistes caeruleus), and house sparrow (Passer domesticus).
Note: BS 42021 does not cover installation of:
BS 42021 on boxes for landing valves for dry risers is useful for:
With extensive renovation of older buildings and new builds which create a totally sealed space, building-dependent species such as swifts can no longer access nooks and crannies in walls or voids under the eaves of buildings. A range of integral nest boxes has been created with the intention of mimicking such holes and providing nest places for birds in buildings.
BS 42021 provides you with dimension and material requirements that can be followed while manufacturing of integral nest boxes. This can address the variability in the quality of many prefabricated bird boxes.
BS 42021 details for the selection, siting, positioning, and installation of integral nest boxes shall be prepared and submitted to the local planning authority. This can help in conformation to building regulations and are easily and unobtrusively built into the fabric of buildings without compromising either the structure or the overall aesthetics.
If you are a manufacturer, BS 42021 can ensure that your Integral nest boxes operate efficiently and contribute to the support of the bird populations using these boxes.
