Name: Heather & Katherine Location: Duplex Nation - Austin, Texas Size: 2,000 square feet Years lived in: Heather bought the house as a duplex in 1999. We converted it from a duplex into a single-family home in 2009 – 2010. Heather and Katherine took a 1948 home in the middle of Duplex Nation— a small community of about 60 duplexes in central Austin— and turned it into the modern, open space of their dreams. Proving even cinder-block construction can be remodeled, the home now has enough space for them to relax, cook, and entertain. We got the House Call back in May, and now we're finally ready to give you the full tour Apartment Therapy-style — with details, pets, and even a dinner party.
