When it comes to amenities, the new LendingTree office in Charlotte, North Carolina, goes above and beyond quite literally considering its “treehouse” areas. With a music room complete with instruments and a karaoke machine and four libraries featuring cozy fireplaces, the 176,000-square-foot office can easily be mistaken for a boutique hotel. Conceived of by Redline Design Group with interiors by the firm and Kelley Vieregg Design, the space reflects the creative, laid-back vibe LendingTree fosters.
