When Walls Kept Us Together

For the vast majority of human history, the idea of retreating to a quiet, private room of one's own was an impossibility. Domestic spaces were inherently communal. Households routinely gathered extended family, servants, apprentices, and tenants together, living and working side by side in shared, multi-use areas.

For a long time, the physical layout of a home was dictated entirely by physics and survival. Medieval homes centered around a single hearth used for both cooking and heating. Because there was only one source of warmth, there was no way to wall it off. The lack of interior walls created an open-plan layout out of sheer necessity, forcing everyone to cluster together around the fire.

Privacy, as it turns out, is largely a thermal technology problem. The 17th century brought the development of chimneys, allowing smaller and more efficient fireplaces to be placed across multiple rooms for the first time. By the 18th century, inventions like the Franklin stove improved heat distribution even further, chipping away at the necessity of crowding around a single central heat source.

As technological advancements like central heating and electric light eventually took over, they completely removed the physical anchor of communal warmth. You no longer needed to crowd around the hearth to survive the winter. But this architectural unbundling of the home did not happen in a vacuum. The modern expectation of domestic privacy arrived hand in hand with the rise of market capitalism, transforming solitude from an impossible luxury into a commodity that could be successfully bought and sold.
