"Micaela Nardella and Oana Tudose’s Brick Biotope is made from sand and plaster and offers a nesting space for birds in the built environment."

Designed as part of a student competition and exhibitied in Milan, this is a design for a bird nest to be placed in existing brick spaces.

"What is FABRIKAAT?

FABRIKAAT is an exhibition at Ventura Lambrate 2012 investigating the re-emerging role of the garden through a “research through making” approach to design and craft. In a digitally saturated world, this body of work celebrates and promotes research, ideas and the nuances of making by hand.

The work exhibited was made during an intensive three-month thematic design studio with integrated seminar and media courses, by students in the Master of Interior Architecture & Retail Design program at the Piet Zwart Institute in Rotterdam, the Netherlands. The spirit of FABRIKAAT became an integral part of the culture, programming and deployment of the courses during this period."

This is something similar to what I was thinking of within the Functional Art design - creating work to be added to existing buildings and spaces.
