Target launched their new Threshold line of homewares with a pop up, life size dolls house in Grand Central Station.  The pre-fab was trucked in and took a construction team 54 hours to assemble. Once complete,  it was kitted out with 3000 products from the new line. With a longevity less than most pop ups, this brand house was only open for 2 days before disappearing. You can take a look at the construction video on Target's  A Bullseye View.
