This Wednesday, the Van Alen Institute is throwing their very first Spring Party in New York City. Tickets to the benefit, taking place at the High Line Hotel, are still on sale, with a variety of price points from a standard party ticket to the high roller “Beaux-Arts Benefactor” costing $25,000. Happening alongs ide the party, Van Alen has partnered with Paddle8 for an auction of architectural experiences, and some of the world’s biggest names—from Iwan Baan to Richard Meier to Brad Cloepfil—have volunteered to potentially spend a little bit of their time with you. Swooning at the opportunities abounding in the auction, A/N has rounded up ten of our favorite experiences up for auction we’d love to try.
