DIY Outdoor Couch, Living Room Couch, Luxury Living Room Couch and Modular Couch. As part of our major outdoor renovation project we built our own modern rustic furniture out of reclaimed wood. LOT’s of furniture to be exact. We built a couch, chair, double-wide chaise and dining table with benches. This post details how we built the couch. Our space is long and narrow so we needed a fairly unique size for the couch, which is the main reason it made sense for us to build our own in addition to wanting something very high quality and an heirloom piece.
