Does a compact home promote well-being? What a recognised source allows us to say, and the design principles that matter.
Does a compact home make life more pleasant, or more difficult? The question comes up often, and the honest answer fits in one sentence: no proprietary AIIA study measures this effect, and no scientific study settles, in a universal way, the question of the link between the size of a home and well-being. What we can do, however, is rely on a recognised frame of reference to understand what, in a home, really matters for the health and quality of life of its occupants, whether it measures 25 m2 or 150 m2.
Understanding the subject
In 2018 the World Health Organization published housing and health guidelines that serve as an international reference. This document identifies four families of factors documented as having a real impact on occupants' health: insufficient available space (crowding), indoor temperature (too low or too high), the risk of accidents in the home, and accessibility for people with reduced mobility. The WHO states that better-quality housing on these points can improve occupants' quality of life and reduce certain health risks.
This framework does not say that a small home is bad, nor that it is good: it shifts the question. What is documented is crowding, that is to say an area that is insufficient in relation to the number of occupants and the use made of it, not the area in absolute terms. A well-designed compact home, sized for the real use of its occupants, is not the same thing as an overcrowded dwelling. It is this distinction, between size and suitability, that is worth knowing before asking the question of well-being in a small space.
Going further
From a design point of view, the first variable that distinguishes a compact space that is pleasant to live in from one that is difficult to live in is storage. In a small volume, every object left visible or poorly stored takes up a disproportionate amount of room, both physically and visually. Storage planned upstream, integrated into the structure rather than added afterwards, limits this clutter and keeps circulation legible, a point we also develop in relation to setting up an independent workspace, where the same logic applies to sharing a small volume between several uses.
Indoor temperature, for its part, is one of the four factors identified by the WHO, and it depends directly on the quality of the building's insulation, not on its area. At AIIA, insulation is part of the habitable base included at no extra cost across the whole Tiny Collection and Maison Collection. Heating and air conditioning, on the other hand, follow a different rule: they are included on the Span, Pod, Line and Vista models; for the other models in the Tiny range, including Fold, this information is not publicly documented to date, and air conditioning is offered there as an option rather than as standard equipment.
Practical advice
The duration and type of use also change the way a compact space is experienced. An independent office used a few hours a day, a second home occupied a few weeks a year and a main residence lived in all year round do not place the same demands on the same volume: the more intense and prolonged the use, the more the organisation of the space and storage matter. It is a question of fit between the project and the real use, far more than a question of well-being in general.
Before judging whether or not a compact home will be suitable, it is therefore more useful to check concrete criteria than to look for a universal answer about well-being: is the area suited to the number of occupants and their real use of the place; is storage integrated into the design rather than added afterwards; are the insulation and, depending on the model, the heating or air conditioning documented for the home under consideration; and does the orientation of the land allow good natural light. These criteria, verifiable model by model, provide a more solid basis than a general promise of well-being.
