Nicer Design created the updated version from timber to allow it to be commercially produced.
"Analyses showed that ceramics weren't suitable due to production, transport and weather resistance issues," Nicer explained. The bird boxes are intended as address markers for houses
According to the designers, the timber was also more durable.
"We found moisture-resistant plywood to be a good alternative, offering excellent nesting conditions, greater durability and predictability than regular wood. We treat the plywood with natural oil and recommend reapplying it every 1-2 seasons to extend the product's lifespan."

The product's redesign also allowed it to be turned into a DIY kit, with a self-assembly process that Nicer hopes will engage younger members of the family.
For this reason Numbird was referred to as a "family project" by Nicer and h...
