Brian and Mika Kleinschmidt from 100 Day Dream Home are used to building homes from the ground up in a tight timeframe. As the only licensed real estate agent in the competition, Mika planned on using her expertise to add value to the home.

Chopped's Ted Allen showed up virtually to introduce the contestants to the Mystery Box Challenge. Each team had to use the materials — chicken wire, faux leather, white tiles and Mason jars — somewhere in their kitchen and dining room designs.

After ripping out the builder-basic cabinets, Brian and Mika met with Rock the Block host Ty Pennington to discuss their plans for opening up the space.

The kitchen should be the heart of the home, but this kitchen seemed closed off. The pony wall made the big space feel tight, so the plan was to remove the wall and cabinetry to start with a clean slate.
