Mereological Syntax of Space (MSS): A Relational Framework for Translating Urban Spatial Structures into Architectural Configuration
This paper introduces the Mereological Syntax of Space (MSS), a relational framework grounded in part-whole logic that translates complex urban spatial structures into architectural configurations by utilizing concepts like the urban and architectural genomes to bridge the gap between urban analysis and architectural design.

Imagine the world of cities and buildings not as a collection of static objects, but as a giant, living puzzle where every piece talks to the one next to it. This is the playground of urban design and architecture, two fields that try to figure out how we move through our world and how we feel inside our homes. For a long time, experts have had a great way to map out the "big picture" of a city—looking at how streets connect and how people flow between neighborhoods. They call this Space Syntax, and it's like having a GPS for social life. However, there's been a frustrating gap: knowing how a whole city works doesn't automatically tell an architect how to design a single building inside it. It's like knowing the rules of a whole football league but not knowing how to set up a single play for one team. This paper, written by Alireza Mostaghni, tries to build a bridge between the city and the building using a philosophy called mereology. Don't let the fancy name scare you; mereology is just the study of "parts and wholes"—how a room fits into a floor, how a floor fits into a building, and how a building fits into a city block. The big question here is: Can we translate the hidden "rules" of a city's layout directly into the design of a building, so the building feels like it naturally belongs there?
The paper introduces a new tool called the Mereological Syntax of Space (MSS). Think of MSS as a universal translator or a secret decoder ring that turns the complex language of a city into the design language of a building. The author suggests that both cities and buildings have their own "genomes." Just like your DNA holds the instructions for your body, a city has an Urban Genome—a hidden set of rules about how its streets, squares, and neighborhoods connect, overlap, and stack on top of each other. Similarly, a building has an Architectural Genome, which is the set of rules that decides how its rooms, hallways, and doors are arranged.
The core idea is that these two genomes speak the same language, even if they look different. The paper argues that we can use a specific set of "grammar rules" to translate the city's rules into the building's design. These rules are based on five simple relationships:
- Adjacency: Things touching each other.
- Connectivity: Things linked together so you can move between them.
- Containment: One thing being inside another (like a room inside a house).
- Overlap: Things sharing a space without fully swallowing each other.
- Hierarchy: Some things being more important or accessible than others.
Instead of just guessing what a building should look like, the MSS framework suggests we can look at the city, map out these five relationships, and then use that map to generate a building design that fits perfectly. The paper uses a method involving relational matrices—which are basically fancy grids or charts—to compare the city's patterns with the building's potential patterns.
The authors present this as a new way of thinking and a method for testing ideas, rather than a magic formula that has already solved every design problem. They show an illustrative comparative case study as a preliminary application, which is like a proof-of-concept demo. This demo suggests that the MSS framework works as a helpful tool for checking if a building's design flows naturally with the city around it. It acts as a "heuristic," which is a fancy word for a mental shortcut or a guide that helps designers find better solutions.
The paper is careful to say that while this approach is promising, it is still in the early stages. It doesn't claim to have replaced old methods or to be the final answer. Instead, it offers a fresh perspective: viewing the city and the building not as separate things, but as parts of one giant, interconnected system. By treating the city as a "part" of a larger whole and the building as a "part" of the city, the MSS framework suggests we can create spaces that feel more connected, logical, and alive. It's a suggestion that if we pay attention to the "syntax" of how parts fit together, we can build cities and homes that make more sense to the people who live in them.
