Designing for Generations

Most community buildings are quietly sorted by age. The children go to one wing, the elderly to another, and the working adults pass through the lobby on their way to somewhere else. We call these places "community centers," but the community they produce is a set of parallel lines that rarely cross. When I began working on YUMAK — an intergenerational community hub stepping down a sloped site in Üsküdar — the first question was not what rooms to include, but how to make those lines intersect.

The answer turned out to be circulation. If the programme is the vocabulary of a building, the route through it is the grammar, and grammar is where meaning lives. YUMAK takes its name from the Turkish word for a ball of yarn, because a single strand of public route winds through the entire section, threading a pottery workshop into a library, a library into a café, a café into a rooftop terrace. You cannot reach the quiet places without passing through the loud ones, and that friction is the point.

Encounter as programme

Designing for encounter means treating the space between activities as seriously as the activities themselves. A child leaving a music workshop and an elderly resident arriving for a chess afternoon should share a threshold, a bench, a moment of light. These overlaps are not accidents to be smoothed away; they are the actual product of the building.

A community is not a collection of rooms. It is the sum of the small, unplanned encounters that happen in the spaces we usually treat as leftover.

In practice, this reframes almost every decision. The stair widens into a landing because a landing is where people pause. The corridor borrows daylight from the workshop beside it because a bright corridor invites lingering. To keep those in-between spaces generous rather than efficient, I found myself returning to a short list of principles:

• Shared thresholds — put the entrances of "young" and "old" programmes near one another, so arrivals and departures overlap.
• Sightlines across ages — let a reading room look down into a games hall, so each group is aware of the other even when not mixing.
• Soft edges — replace sharp corridors with widened landings and window seats where a five-minute pause can happen.
• A single public spine — one continuous route everyone shares, rather than segregated wings that never meet.

None of this is expensive. It is mostly a matter of where you spend your generosity — in the rooms, or in the spaces that connect them. Intergenerational design argues, gently but insistently, for the latter. A building that brings a grandmother and a stranger's child into the same warm stairwell for thirty seconds has already done something that no dedicated "activity room" can guarantee. The architecture does not force the encounter; it simply refuses to prevent it.
