From fixed floor plans to flexible home design
Flexible home design is the practice of creating adaptable living spaces that avoid rigid room labels and hierarchies, so interiors can support changing relationships, family structures, and life stages instead of locking occupants into a single nuclear-family script. The familiar two- or three-bedroom layout already carries assumptions: parents take the largest room, children sleep down the hall, or the person who pays more claims the bigger bedroom. These multipurpose room layouts may look neutral, but they quietly prescribe who belongs where and how domestic life should be organized. In my view, that quiet prescription has become the real problem in modern home architecture. As households fragment, recombine, and age in place over decades, homes that cling to preset roles feel increasingly out of step with how people actually live, love, and care for one another.
When modern home architecture stops telling us how to live
Eduardo Mediero argues that the real-estate shorthand of “three-bedroom apartment, living room, kitchen, corridor” says more about how a property is sold than how it feels to inhabit it. According to Mediero, “the market has reduced architecture to a system of programmatic labels,” displacing questions of light, ventilation, proportion and spatial quality. His studio’s work treats the home as a backdrop for life, not a script that dictates it: “The house had to be more of a backdrop against which life happens than a structure that determines how it should happen”. In projects like the 85-square-meter Ronda House in Murcia, he replaces a conventional hierarchy of rooms with an asymmetric chain of distinct but programmatically generic spaces. This approach to flexible home design is not about gadgets or sliding walls; it is about stripping away architectural instructions so inhabitants decide what each room is for.
Multipurpose room layouts that grow with relationships
Designers challenging domestic hierarchy are united by one insight: relationships change far faster than buildings. A couple separates, a friend helps raise a child, an older parent moves in, or two households merge for a few years and later divide again; the building may stand for a century while the household reshapes itself inside several times. In Lara House, a 65-square-meter apartment in Madrid, HANGHAR organizes four visually connected rooms without preset functions; the fireplace and kitchen are almost the only fixed anchors, while the rest can become bedroom, studio, or shared lounge as life requires. Instead of chasing flexibility through foldaway desks and transforming beds, the architecture is made less instructive so that what happens inside a room can change over time. This is agency in practice: a piece of the plan can change allegiance as people change their relationship to one another.
Adaptive precedents: from seventeen micro-rooms to shared thresholds
Kazuyo Sejima’s House in a Plum Grove is an early, radical statement of adaptable living spaces. Within a compact 77-square-meter house for three generations, she divides the interior into seventeen very small spaces across three floors. Some rooms shrink to the scale of a single piece of furniture; her son’s double-height bedroom is barely larger than his bed. Instead of three bedrooms plus a living room, domestic life is broken into many activity-based pockets, stitched together visually through openings in thin steel plates so family members stay close while enjoying different positions in the home. Elsewhere, overlapping apartments such as Kufu 142 use level changes and corners to create privacy with few permanent partitions; where units intersect, pieces of space can be assigned to one home or opened between two, allowing neighboring households to share childcare or work together. Flexibility here is about reconfigurable relationships, not furniture tricks.
Beyond the nuclear family: what comes next for adaptable homes
The move toward adaptable living spaces is not a passing style; it responds to a deep cultural shift away from housing standards built around parents and children. Housing regulations and typical plans in England helped consolidate layouts organized around nuclear families, fixing expected room sizes and relationships between domestic spaces. Today, Mediero’s work questions which parts of domestic architecture are necessary and which feel inevitable only because we stopped challenging them. More recently, his investigation has begun to move beyond the interior plan into materials, assembly and territory, as in Casa Guadalupe, which asks how resistance to predetermined solutions can enter the construction process itself. HANGHAR was founded as a ten-year practice and is scheduled to cease activity on December 31, 2030, a finite lifespan intended to create urgency to test and push these ideas as far as possible. If designers keep prioritizing inhabitant agency over prescription, the default “family apartment” may soon be the exception, not the rule.
