Andrew Anderson — Between the Blocks

In one sentence

The "interblock" parks of Sofia were a masterpiece of socialist urban planning—designed to provide every citizen with an equal share of nature—but because they were never officially "protected," they are now being sold off to private developers in a chaotic, unregulated transition to capitalism.

Why read this (who it's for)

This is for urban planners, architects, and anyone interested in the sociology of public space. It explains how the intent of a city's design (collectivism vs. individualism) dictates the physical reality of our streets. You will learn how to identify the "hidden" infrastructure of social cohesion and understand why the loss of "unclaimed" public space is a direct threat to community life.

The big idea

The "interblock" parks of Sofia were not accidental; they were a deliberate, radical experiment in "architecture for society." Under the Bulgarian Communist Party, planners rejected the "bourgeois" American model of single-family suburbs in favor of a high-density, high-greenery model inspired by French modernism and the British Garden City movement. The goal was to treat nature as a public utility—something that could be "parsed" and distributed equally among all citizens.

However, the very mechanism that allowed for this rapid, egalitarian expansion—the state's total control over land—created a massive legal vacuum. Because the government owned everything, they never bothered to "protect" the specific green spaces between the buildings. When the regime collapsed and land was returned to private owners, these parks were left in a legal gray zone. Today, they are being sold to oligarchs for private development because they were never officially registered as "parks," illustrating the tragic irony of a system that succeeded in creating a public paradise but failed to provide a legal framework to save it from private greed.

Key ideas

The "Architecture for Society" Model

• What it is — A planning philosophy where the city is designed as a "machine" for living, where housing, recreation, and work are separated into distinct, functional zones.
• Why it matters — It shifts the focus from individual property to collective utility, where the "public realm" is the primary priority.
• In the book — The planners in Sofia used "open geometry" to ensure that residents had access to light and green space, creating a "corridor of green air" through the city.

The "Parsing" of Nature

• What it is — The idea that nature can be treated as a measurable, equal share of a city's resources, much like electricity or water.
• Why it matters — It justifies the creation of "interblock" spaces—not as grand, singular parks, but as a continuous, walkable "river" of greenery that connects every apartment.
• In the book — The planners wanted to ensure everyone had a "certain amount of space in total," leading to the creation of hundreds of small, un-fenced green spaces between blocks.

The "Luchnikov Act" and the Ownership Vacuum

• What it is — A 1990s policy designed to return nationalized land to its original owners after the fall of communism.
• Why it matters — Because the government had seized everything, the "original owners" were often former farmers whose land was now covered by massive apartment blocks, leading to a "nightmare banquet of disasters" regarding land rights.
• In the book — Since the parks were never officially listed as "protected," they were essentially "free" for anyone who could claim a piece of the underlying land.

The Collapse of Maintenance (Lenin’s Saturdays)

• What it is — The transition from state-funded maintenance to "volunteer" maintenance (Lenin's Saturdays) and eventually to total neglect.
• Why it matters — It shows that public space requires constant, active investment; without a functioning social contract, "public" spaces quickly become "no-man's-lands."
• In the book — After the 1990s, the parks fell into such disrepair that they looked like war zones, and the public eventually "gave up" on the idea of the government providing for them.

The Three Utopian Visions

• What it is — The contrast between Ebenezer Howard’s "Garden City" (collectivist/decentralized), Frank Lloyd Wright’s "Broadacre City" (individualist/distributed), and Le Corbusier’s "Radiant City" (centralized/monolithic).
• Why it matters — It provides a framework for understanding why Sofia looks the way it does: a hybrid of Howard’s collectivism and Le Corbusier’s centralized geometry.
• In the book — Kurt Kohlstedt explains that while Howard wanted "rings" of greenery for shared ownership, Le Corbusier wanted "towers" in a park for a centralized urban machine.

Frameworks & tools

The Three Utopian Models of Urbanism

Use this to categorize and critique any new urban development proposal:

1. The Garden City (Howard): Focus on Collectivism. Small, autonomous "nodes" connected by rings of greenery. Power is decentralized; people share ownership of their "slice of paradise."
2. Broadacre City (Wright): Focus on Individualism. Massive, low-density plots for every family. It assumes technology will make density obsolete. It is "suburbia on steroids."
3. The Radiant City (Le Corbusier): Focus on Centralization. High-density "machines" (apartment blocks) set in vast open spaces. It is a regimented, geometric system where every part serves the whole.

Memorable examples & stories

The "Hidden" Forest of Sofia

Andrew Anderson describes how, from the ground, the neighborhood of Krasno Selo looks like a "mess of winding footpaths and untamed greenery," but from a high-up apartment, it reveals itself as a "forest" of trees with apartment blocks poking up between them. Lesson: Perspective changes the perception of urban chaos into intentional design.

The "Grandma" of the Park

Ashira Morris recounts a woman who, despite the collapse of the state-run "Lenin's Saturdays," still comes out to sweep the pavers and snap branches to clear the trash. Lesson: Public space survives only when individuals take personal responsibility for the "commons."

The "Bourgeois Fascist" Suburb

The Bulgarian planners explicitly rejected the American model of single-family homes, calling them "bourgeois fascist," and instead opted for the "Radiant City" model to ensure a more egalitarian distribution of space. Lesson: Urban design is never neutral; it is a political statement about who is allowed to own space.

Key quotes

"The government and the people were supposed to elevate the public realm... and what better way to elevate the public realm but by having really magnificent public spaces, including parks." — Sonia Hirt Why it matters: It highlights the socialist intent to use aesthetics and space as a tool for social engineering.

"The situation just got more and more complicated. What started out as a very simple and, on paper, elegant solution... quickly became an absolute nightmare banquet of disasters." — Andrew Anderson Why it matters: It illustrates the danger of "well-intentioned" policy when it meets the messy reality of private property.

"They were smart enough to know that these were fundamental truths and that no matter what you built in between, these things were required... the building blocks of a good city." — Roman Mars (referring to light and greenery) Why it matters: It identifies the non-negotiable requirements for human habitation.

How to apply it

This week

• Identify your "Interblock": Find the green space or public area in your neighborhood that feels like a "common" area. Who maintains it? Is it a "protected" space or a "leftover" space?
• Analyze the "Architecture of Intent": Look at a nearby building or park. Does it feel like it was designed for collectivism (shared use, public focus) or individualism (private gates, exclusive use)?

Ongoing

• The "Grandma" Principle: When public maintenance fails, don't wait for the city. Act as a steward of the immediate "commons" (a sidewalk, a small garden, a community corner).
• Advocate for "Protected" Status: When discussing local development, ask: "Is this space officially protected, or is it just 'unclaimed'?" Understand that "unclaimed" means "available for sale."

Common pitfalls

• The "Communism vs. Capitalism" Fallacy: People often assume communist cities were designed poorly because of the regime. However, the "interblock" model was actually a highly sophisticated, intentional piece of architecture that happened to be funded by a socialist state.
• The "Free" Space Myth: Just because a park is currently "public" doesn't mean it is "protected." If it isn't on a formal registry, it is essentially a private lot waiting for a developer.

• The Power Broker by Robert Caro: For understanding how urban infrastructure is shaped by the sheer will of individuals in power.
• The Garden City by Ebenezer Howard: To understand the original roots of the "green ring" and "decentralized" urban planning.

If you remember only three things

• The "interblock" parks were a masterpiece of egalitarian design intended to give every citizen a share of nature.
• The collapse of the state created a legal vacuum where "unprotected" public spaces became easy targets for private developers.
• Public space requires a social contract: Without active maintenance (either by the state or the community), the "commons" will eventually be sold or decay.

Internalize it

• Reflection questions

  • If my neighborhood's green space disappeared tomorrow, what specific social functions (playground, social club, etc.) would I lose?
  • How does the "Radiant City" model (high-density towers in green space) compare to my current living situation?
  • What "unclaimed" spaces in my city are currently in "development purgatory"?

• Flashcards Q: What was the primary goal of the "interblock" parks in Sofia? A: To provide every citizen with an equal share of nature and public space as an extension of their apartment.

Q: Why were the parks not protected after the fall of communism? A: Because they were never officially listed as "protected" during the communist era when the state owned all land.

Q: What is the difference between Howard's Garden City and Le Corbusier's Radiant City? A: Howard's is a collectivist, decentralized "necklace" of rings; Le Corbusier's is a centralized, regimented "urban machine" of towers.

Q: What was "Lenin's Saturdays"? A: A system of "volunteer" maintenance where residents were expected to clean and maintain the public spaces between blocks.

Q: What was the "Luchnikov Act"? A: A 1990s policy to return nationalized land to original owners, which created a complex legal mess regarding who owned what in the city.

Fidelity note

This summary is based entirely on the provided transcript. I am confident in the historical timeline of the Bulgarian transition and the architectural definitions provided by Kurt Kohlstedt. The specific "names" of the acts (Luchnikov) and the specific architects (Le Corbusier, Howard, Wright) are directly from the text. The "three utopian visions" are a synthesis of the expert's breakdown in the final segment of the show.
