Affect as Evidence Under Spatial Compression: A Staged Autoethnography of Multifunctional Small-Space Living and Its Embodied Limits

This visual essay tests whether “small space multifunctionality” truly delivers efficiency and comfort. Using a staged autoethnography in a single dwelling, the author progressively restricts usable area while recording nightly Self-Assessment Manikin (SAM) ratings and basic physiology, and documenting change through a fixed-angle photo stream, floor plans, user-journey maps, micro-scenes, and selected research notes. Findings show a clear drift from variety to bare survival as space contracts: switching work (clearing–unfolding–resetting) rapidly absorbs attention and energy; eating, sleeping, and toileting are forced to share surfaces and air, eroding dignity and rest; the trial is curtailed in the final stage due to acute distress, indicating a hard embodied limit to compression. Read alongside media scripts of “making do small space” to get “happiness,” the burden is recoded as virtue. Rather than proposing a universal standard for minimum dwelling size, this visual essay offers an evidentiary method that keeps efficiency claims accountable to lived thresholds. Two recurring mechanisms become legible through the staged protocol: Conversion Friction (the hidden operating cost of small-space living—time, attention, and bodily wear spent on constant reset-and-reconfigure cycles so the home can remain usable) and Functional Overload (the breakdown that occurs when incompatible domestic functions are stacked onto the same micro-space, especially when recovery-critical zones—rest, privacy, basic bodily separation—are treated as convertible rather than protected. At that point, multifunctionality stops being a design feature and becomes a failure mode: the home can be operated, but it can no longer restore). The conclusions are therefore deliberately bounded: calibrate multifunctionality, account for conversion friction, prevent functional overload by protecting recovery-critical zones from entering the conversion loop, and evaluate not only spatial density but the felt quality a space sustains.
