Just in time for Halloween comes a spooky story of speculation and specters in the world of real estate. Joshua Comaroff, a professor at National University of Singapore, is the author of Spectropolis: The Enchantment of Capital in Singapore. He tells Unfrozen that, despite being one of the most assertively modern nations in the world, mysticism and geomancy are very much part of the design and construction process in the island na...

Depending on how you look at it, it is either a great or rough time out there for speculative fiction, as reality continues to bite at the heels of even the most dystopian visions.

Rem Koolhaas is nothing if not enigmatic, which makes him and his first major built work, the Villa dal’Alva, Paris (1990), an ideal first subject of the “Gumshoe” series of architectural mysteries. Cutting through the conventions of academic jargon and trade press, The House of Dr. Koolhaas reopens the “cold case” of Koolhaas and examines evidence in a pulp-detective novel format. Unfrozen turns the lamp back on writer/editor team...

Dismayed by the destruction and death in Gaza? Fear not, the wizards at Boston Consulting Group have a plan – a 38-slide deck that will Make Gaza GREAT Again. It’s a molten nugget of consultant-speak, SimCity planning moves, weirdly proportioned AI slop renderings, and tokenized real estate transactions that place a thin veil of “solutioneering” over what looks an awful lot like ethnic cleansing. Don’t worry – it will all be covere...

Hillary Brown, Professor Emerita of Architecture at the City College of New York, joins Unfrozen to discuss her book Revitalize | Resettle, which explores how climate migration and rural revitalization can solve interlinked crises.

Instead, she proposes strategic resettlement in small towns and “...

Chicago’s Wrigley Building, constructed in 1921, is the “whited sepulcher” of Michigan Avenue, gleaming in terra cotta like the rows of teeth ostensibly cleansed by Wrigley’s Chewing Gum, the company that built the Beaux-Arts edifice. But its extravagant looks are only part of the story. Unfrozen hosts Robert Sharoff and William Zbaren, who wrote and photographed the new book from Rizzoli, The Wrigley Building: The Making of an Ico...

    Are You A Charlotte?

    In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
