New glazing and an angular lobby crossed by a catwalk are among the enhancements that US architecture studios Eskew Dumez Ripple and CambridgeSeven have made to a 1990s nature museum in Louisiana.

Located in the heart of New Orleans, the Audubon Aquarium and Insectarium sits on a site overlooking the Mississippi River.

The museum – which encompasses 68,158 square feet (6,332 square metres) – is operated by the Audubon Nature Institute, a leading nonprofit dedicated to environmental conservation.

The museum offers exhibits focused on wildlife and habitats around the globe, from Louisiana bayous to South American rainforests.
