Envisioned by NYC designer Joe Doucet, Annex is an intriguing table collection made up of hand-honed marble units. The Annex Side Table and the Annex Coffee Table were commissioned by the Cooper-Hewitt National Design Museum in New York and are currently available for purchase at $2,650. The special thing about this limited furniture edition is that its assembly requires user interaction.

Ordering a living room table and discovering a pack filled with marble panels might come as a surprise to a home owner, but this is not exactly the case with this project. According to the designer, the tables can be easily assembled and only use only gravity to securely join them together. Check out the elegant and subtle ‘X’ that remains visible from the base once the pieces are merged! Despite this unusual setting-up process, the designs are as sturdy and secure as can be.  [Photography: Kendall Mills]
