Lighthaven East - A Feasibility Study

As a bureaucrat, my role is to annoy my friends. Someone voices an idea, “Wouldn’t it be nice if…” or “I wonder if we could…” I make a note. I do some estimates. If it pencils out, I’ll bring it back up, week after week. The discussions are fun, but also practical. We’ll test the waters, what would be a minimum viable scheme? What’s easy, what’s hard? Who could do the hard parts? Over time the idea gets more detailed, specific, feasible. I’ll pull out a calendar. Soon our scheme has co-conspirators, action items, even a budget. It’s just good staff work. I’ve been hearing whispers in the wind for a year now.  “Imagine if we had something like this in DC.”  “Where can I host an event that might get a dozen or a hundred people?”  “It’s such a pain in the ass to book event space in the Capitol.”  “I think this person has started to see what’s coming, where can they go to get caught up?” “The community seems to be growing but it’s all fragmented in group chats.”  “How is no one planning an afterparty, that’s clearly the highest leverage intervention!?” “Why can’t every wall be whiteboards?” These are all variants on a theme: “Lighthaven East.”  I did some digging. I’m happy to report that this could work. There’s strong demand. There are good options for supply. Funding, staffing, resources, property, and permits are all doable. The hard parts are diligence, agency, and will. This project needs a champion, but it’s a thing someone can simply choose to do.  Note: There will be a workshop about this idea at LessOnline, sign up! How Lighthaven Works Legally speaking, Lighthaven is a confusing category error. It was once the ramshackle “Rose Garden Inn,” with several buildings, a hotel license, and a history of event use. After extensive renovations, it is now a 30,000 square foot campus used for conferences, retreats, office space, and medium-term lodging. The property is owned by Lighthaven LLC and financed by an interest-only mortgage held by a philanthropist. The LLC runs the property, hosts internal events, rents conference and office space to external customers, and sells hotel stays. Lighthaven LLC is itself owned by Lightcone Infrastructure, a non-profit that among other things runs LessWrong. Economically, Lighthaven LLC generates an operating profit comparable to its cost of capital. The mortgage is $20 million at 5% interest, for an annual interest payment of $1 million. Lighthaven LLC had $3.25 million in revenue in 2025. Events and hotel stays generated an operating profit of roughly $850k, almost enough to pay the $1 million annual interest payment. Office space seems to be offered at cost. Lighthaven LLC’s projections of $3.5 million revenue in 2026 should generate an operating profit sufficient to fully fund its annual interest payment, though bookings are currently sparse for this fall.  In practice, Lighthaven is the best event venue I’ve ever seen. I won’t belabor that point in this post, but if you haven’t been to Lighthaven, see some of its many rave reviews in this footnote.[1] Lighthaven LLC does not maximize profits–events are often experimental or designed primarily to support the Berkeley community, rather than the booking going to the highest bidder. Some event organizers are not charged, others are offered discounts on rates that are already lower than similarly sized spaces at hotels. This pricing strategy generates significant positive spillover effects and goodwill, demonstrated by the community’s strong response to Lightcone’s two fundraisers. While Lighthaven was a significant cost center for Lightcone in 2023 and 2024, by 2026 it is better modeled as supporting the parent non-profit.  Conceptually, Lighthaven is a monastery. Its main purpose is to support good scholarship “dedicated to making humanity’s future go better.” Its abbot skillfully wields an awkward mix of temporal, cultural, and political authority. Monasteries often support their ecclesiastical mission by selling craft goods such as beer, eggs, mushrooms, or furniture–Lighthaven instead sells conference space. Unlike an abbey selling produce for revenue, the conferences at Lighthaven also further Lightcone’s mission. Lighthaven’s scholars-in-residence synergize with its mission, contributing to and benefiting from the events held on the property. These aspects combine into a whole: Lighthaven is the place to go to think out loud. Comfortable perches encourage deep thought. Inviting conversation nooks encourage you to refine your ideas with friends, themselves helpfully provided by the events and scholars-in-residence. Beautiful seminar rooms encourage you to share your ideas, refining your presentation to best convey them to others. Once your ideas are fully baked, get the word out via your laptop, the antique typewriters, or having a friend interview you in the podcast studio. What Does DC Need? DC culture has a Lighthaven-shaped hole. Politicians have started to notice that they are confused about the future of
