The brothers compete to see who can design the most efficient and attractive family room, office and laundry spaces with their mom, dad and Egypt Sherrod judging. Whoever wins this round gets to perform on a trapeze in Vegas's legendary Circus Circus act.

The brothers tackle their final spaces when Season 4 comes to a close with Jonathan and Drew taking on the front and back yards. Later, the houses go on the market in Las Vegas and whoever makes the most profit wins and donates their proceeds to a local charity.
