Adaptive Domesticity
Why does a Tokyo apartment feel different from a Paris one? We started counting.
Walk into a Tokyo apartment. The kitchen flows into the living room. No door, no threshold. It feels open, almost exposed.
Walk into a Paris apartment. The kitchen hides behind a door. Always. The salon is for guests; the kitchen is for work. They don't mix.
Walk into an Istanbul apartment. There's a formal salon for guests, completely separate from the family living room. Two worlds under one roof.
Why? These aren't random preferences. They're cultural patterns encoded in space. Privacy gradients. Hospitality protocols. Rules about who sees what. This working note reads those patterns through published floor plans and typology literature, and asks which of them can actually be counted.
Furniture as Evidence: Semper's claim, taken literally: joint complexity may predict spatial hierarchy. A pattern we keep seeing in typologies, and still want to test properly.
Theoretical Framework
Furniture Scale
Joinery typologies as cultural evidence. Semper's claim, read literally: cultures with complex joinery tend to build more nuanced room transitions. For now a hypothesis, not a proof.
Room Scale
Threshold counting. How many doors, level changes, and implied boundaries stand between street and the most private room? Countable on any plan.
Typology Scale
A century of published floor plans, 1920 to today. Adjacencies, circulation, and privacy gradients read across housing types.
Cultural Synthesis
The patterns feed a typology vocabulary we want SpaceCraft to eventually understand: a scanned room means more when its cultural grammar is legible.
Research Process
Read Typologies
Published plans and typology literature from five city grammars
Count Thresholds
Privacy gradients and buffer zones read plan by plan
Index Patterns
Adjacency, visibility, and hospitality indices per typology
Synthesize Vocabulary
Cultural pattern vocabulary for future product integration
Research Phases
Typology Reading
Comparative reading of published plans and typology literature across five city grammars: Tokyo, Paris, Istanbul, Marrakech, Los Angeles.
Threshold Mapping
Counting privacy thresholds and buffer zones plan by plan; building the gradient index.
Joinery Hypothesis
Testing Semper's furniture-to-space claim against documented joinery traditions. Honest status: not yet done.
Product Integration
A cultural pattern vocabulary for SpaceCraft's scanned rooms. Planned.
Key Metrics
Key Thinkers
Gottfried Semper
Semper argued that architecture begins with textile weaving and furniture joinery, not monumental form. We take him literally and read furniture joints as spatial evidence.
Gaston Bachelard
The Poetics of Space taught us that houses are emotional, not just geometric. Corners protect us. Attics dream. Cellars store fears. Our indices try to count what Bachelard described.
Junichiro Tanizaki
In Praise of Shadows explains why Japanese spaces value penumbra while Western spaces chase illumination. There's no universal 'good design.' There are cultural grammars.
Edward T. Hall
Hall invented proxemics: the study of human spatial relationships. Comfortable distances vary by culture. Our privacy gradient metrics extend his framework to plans.
Case Studies
Tokyo Compact Typology
JapanAround 32 square meters with no doors between living spaces. Privacy through ritual, not walls. Morning routines choreographed to avoid collision; the plan assumes it.
Paris Haussmann Typology
FranceClassic bourgeois layout. Kitchen hidden from salon. Service corridor for staff. Roughly 95 square meters with four distinct threshold conditions.
Istanbul Multi-Generational Typology
TurkeyGuest salon completely isolated from family living. Often a separate entrance for the grandmother's quarters. Hospitality and intimacy don't share space.
Comparative Analysis
Tokyo
The Flowing SpaceNo doors between living areas. Privacy through ritual, not walls. Kitchen is the social center.
Paris
The Hidden KitchenKitchen always separate. Service and served spaces don't mix. Guests see the salon, not the mess.
Istanbul
The Guest SalonTwo living rooms: one for family, one for guests. Hospitality has its own architecture.
Marrakech
The Courtyard HomeBlank exterior, rich interior. All rooms face the central court. Maximum privacy from street.
Optimization Results
How many thresholds between street and most private room?
Scenario model: typology indices from our plan readings
Key Findings
Thresholds are countable. The distance from street to the most private room can be read off any plan: five thresholds in Istanbul and Marrakech typologies, one in an open-plan LA loft.
1 to 5 thresholdsTurkish apartment plans carry roughly 2.3 times more buffer zones than Tokyo plans. Hospitality protocols are encoded in circulation.
2.3× more buffersParisian kitchens read consistently smaller than Tokyo kitchens in same-sized plans, and always behind a door. The privacy gradient trumps cooking space.
Smaller, always hiddenFurniture joints may predict spatial hierarchy. Cultures with complex joinery (Japan, Scandinavia) tend to have more nuanced room transitions. A pattern we keep seeing, not yet a proof.
Hypothesis to testHonest Limitations
This is plan-reading, not fieldwork. Published plans show intention; they don't show how families actually live.
Our sources skew middle-class and urban. Social housing and luxury follow different grammars.
The joinery-to-hierarchy link is a hypothesis we find compelling. We haven't tested it at a sample size that would satisfy a statistician.
Plans from 1920 and life in 2026: building stock evolves slower than domestic ritual.
Conclusion
Domestic space encodes culture. The way a door is positioned, where the kitchen sits, how many thresholds separate street from bedroom: these aren't random choices. They're cultural grammars. Some of them can be counted on any floor plan; this note is our running attempt to count them carefully.
Limitations
- Plan-reading, not fieldwork
- Middle-class urban focus
Future Directions
- Extend to social housing typologies
- Test the joinery hypothesis properly
