Keith plans to flip a 917 square foot, two bedroom, one bath bungalow in a fast growing neighborhood in Denver, Colorado. Because the house was built in 1920, the home has small rooms and limited living space compared to modern homes in the area.

A Denver couple with two young boys is expecting a new baby, and they need more room in their 100-year-old house. Keith rips off the roof and adds a dormer, giving them a new master suite, nursery and a fun bedroom for the boys. He also opens up the ground floor and creates a stunning new kitchen.

An investor brings Keith a promising flip prospect that another builder started, but abandoned in the early stages of demolition. It's an early 20th Century Craftsman bungalow with an unfinished basement and a classic Craftsman style interior. Keith and the partner triple the home's livable square footage by finishing the basement, adding a second story and putting in all-new mechanicals with contemporary Craftsman interior finishes.

A chef and his wife feel cramped in their 100-year-old Victorian cottage with no master suite and an outdated kitchen. Keith adds a stylish master suite, creates a modern kitchen and gives the unique exterior a bright new face.

Keith pays a premium for a house on a huge corner lot but quickly runs into trouble when he finds a giant sinkhole under one bedroom. Despite that setback, he creates a stunning open floor plan featuring a modern kitchen, tile fireplace with wraparound stairs and a majestic overmantel that extends up through the second floor.

Keith turns a bland, yellow-brick bungalow into a stunning Spanish-style mansion. He excavates the basement to provide more headroom, knocks down the back wall to extend the house and turns the dated boxy interior into a modern, open, light-filled space. Keith puts the bedrooms on the new second floor and above it all, he creates an enormous rooftop deck with a spectacular mountain view.
