About Us

Genesis Nest Boxes operates from scenic Killarney County Kerry Ireland.

Here in one of the most beautiful places in God’s creation the range of Genesis Nest Boxes, mostly for endangered species is manufactured by hand.

We specialize in commercial nests for Swifts, Barn Owls, Kestrels, Sparrows and Otter Holts, however we also manufacture bespoke nest boxes to suit any situation.

We also manufacture and erect Swift Towers ranging from 12 to 24 nests, fitted with audio, cameras and solar charging facilities. Although we install many of our own commercial boxes, we install all our bespoke boxes and towers ourselves.

In 2010, Dr Brin McDonnell (Duhallow Bird Watch Club) and John Lusby (Bird Watch Ireland) asked Stephan to manufacture the Barn Owl Nest Boxes for the Barn Owl Raptor project in Duhallow (effective 2010 to 2015).

By 2015, most if not all of the boxes made from Marine Ply and fitted in outside locations had started rotting to the extent that they were virtually useless.

This prompted Dr McDonnell to approach Stephan with a view to producing a nest box that would overcome the Irish weather.

Many materials were tried, tested, and rejected, until finally Stephan discovered Magnesium Oxide Wall Board – MgO for short. This board produced only in the Pacific Rim countries and used extensively in the East in the building industry as a substitute for Cement fibre and plaster of Paris boards, we had finally found a suitable product with which to produce our nest boxes.
