Alison Victoria from Windy City Rehab returned from Season 1 of Rock the Block to pair up with Mike Holmes from Holmes and Holmes. "I'm a designer and [Mike's] a genius in the build. It's a partnership like no other," said Alison.

Chopped's Ted Allen surprised the designers with a Mystery Box Challenge to see how well they could think on their feet. The teams had to use chicken wire, faux leather, white tiles and Mason jars somewhere in their kitchen and dining room designs.

Alison and Mike took Rock the Block's host Ty Pennington through their kitchen concept. Between the two of them, they've done over 500 kitchens, so they were confident they could master the Week 1 remodel.

The basic kitchen didn't have an easy, functional layout. Alison and Mike wanted to remove the pony wall as soon as they saw it and turn the island to face out toward the living room. "We're going to make it bigger, more comfortable, more functional," said Mike.
