Genesis Nest Boxes

Genesis Nest Boxes is are the only Irish manufacturer of nest boxes made from ResCom® Cellular Magnesia Cement board. This is one of the best cementitious boards in the world if not the best. We only work with ResCom® material to manufacture all of our products.

ResCom® board ( is an earth friendly product that has no “Volatile Organic Compounds” (V.O.C.s). It has many qualities that suit the Irish climate and so is a perfect fit for nest box construction. For more details about ResCom® CMC board, visit our Material Information page.

We would like to extend our sincere sympathies to the family and friends of Paddy Sheridan (shown with Stephan on the photo above) who sadly passed away on Tuesday 8th December 2020.

The Genesis Nest Box Product Range

Our boxes are purpose made for endangered species such as Swifts, Sparrows, Kestrels and Barn Owls. We have recently broadened our range to include colourful garden bird nest boxes. We also manufacture bat boxes, silt traps, sand martin nests and basically anything bespoke we are asked to produce.

Our nest boxes are waterproof, mould proof, vermin proof and fireproof. Consequently, the nest boxes are well suited for outdoor use. They do not suffer from condensation inside and will not rot, nor be chewed or eaten by vermin.

Our range includes single, double and triple entry soffit fit or built in swift nest boxes, owl and kestrel nest boxes. Furthermore, we manufacture an anti-predator range for swifts, therefore, the swifts’ nests are less likely to be raided by predators. These products are all available from our shop.

Wild Kildare use Genesis Nest Boxes extensively in their projects, but above all, they are doing a splendid job of helping swifts, which are an endangered species. They have completed many projects in conjunction with schools and Tidy Towns. The 6 Swift towers erected in Duhallow region of West Cork are designed to meet particular project needs. 

We can produce any size of nest box or swift tower, to any specifications. Anyone who would like quotes for nest boxes, for specific projects, can contact Stephan by using the information on our contacts page.

All our nest boxes are painted with cork. This makes our boxes totally insulated against heat and they are also waterproof, yet the cork breathes, and our green footprint is minute, as both our materials are environmentally friendly. Each box is fitted with 2 brackets, these are sold complete with concrete screws ready for installation.
