At Yoko Kloeden Design, when we take a brief for a new project, we ask our clients to provide a full inventory of their storage requirements. What arrives is a laundry list: seasonal wardrobes, sports equipment, wine, books, kitchen appliances used once or twice a year, collections accumulated over decades. The brief then becomes a request for bespoke joinery — a dozen pieces, sometimes more — to house all of it. Often alongside plans for a rear extension, a loft conversion, or a reconfigured kitchen.
The instinct is always to build more. More space, more storage, more rooms. But the question we find ourselves returning to, quietly, is a different one: what if a third of this simply went?
This is not an article about tidying. It is about a Japanese philosophy called Danshari (断捨離) — and why the first act of any serious renovation is not design, but letting go.
What Danshari Means
Danshari was developed by Hideko Yamashita in 2009, drawing on the yogic philosophy of Masahiro Oki, the Japanese yoga master who founded Oki-do Yoga. The word is composed of three characters, each representing a stage in a deepening process. Dan (断) means to refuse what is unnecessary — to stop new things entering. Sha (捨) means to dispose of what no longer serves — to release what has accumulated. Ri (離) means to separate from the attachment itself — to let go not just of the object, but of the need to hold on.
It is the third stage that distinguishes danshari from decluttering. This is not about organising possessions more efficiently or investing in better storage solutions. It is about examining the relationship between yourself and the things you keep, and having the honesty to recognise when that relationship has ended. Yamashita’s insight was that the living space is not merely a container for objects — it is a reflection of the self. A home crowded with things we no longer need is a home that cannot support who we are becoming.
The word has gained wider recognition in recent years through social media and publishing, but its roots are deeper than the current wave — and its application to architecture is, we believe, where it becomes most powerful.
Cluttered Space, Cluttered Mind
Research in environmental psychology has consistently shown that visual clutter raises cortisol levels, fragments attention, and undermines the sense of rest a home should provide. A room filled with objects — however beautiful individually — creates a low-level cognitive demand that the brain cannot switch off. The eye darts. The mind follows. For anyone returning from a demanding professional life, this is the opposite of what home should offer.
We often say that a cluttered space produces a cluttered mind. This is not a metaphor. It is a spatial condition, measurable and felt, and it needs to be addressed before anyone picks up a pencil. No amount of architectural intervention — no extension, no bespoke joinery, no reconfigured layout — will produce a calm home if the volume of possessions remains unchanged. The container may grow, but the restlessness stays.
The Honest Questions
In our practice, Danshari does not arrive as a lecture or a service. It surfaces through conversation — through the honest lifestyle questions we ask during the briefing process. These questions are not designed to catch anyone out. They are designed to help our clients discover what they actually need, as distinct from what they assume they need.
We ask: what kind of cooking do you do? And the client pauses, then admits they do minimal cooking — perhaps a few simple meals during the week, eating out at weekends. The show kitchen they had briefed, with its double ovens and island preparation area, would consume space better given to a generous table where friends and family gather. The kitchen shrinks. The life of the home expands.
We ask: do you read much? Where do you read? And the answer comes that actual reading happens on a Kindle, in bed or on the sofa. The study bookshelf — the one that featured prominently in the brief — is largely a Zoom background. The home office changes shape entirely.
These are not trick questions. They are simple, respectful enquiries into how life is actually lived, and the answers often surprise the person giving them. Through this process, clients naturally arrive at their own version of danshari — releasing the attachment to things they thought they needed, and discovering that what remains is closer to the home they actually want.
What Opens Up
When a third is removed — not through forced minimalism but through honest assessment — the home begins to reveal itself. Proportions become legible. Light reaches further into the plan. Circulation opens. We often show clients rendered views of the same space with and without Ma (間) — the breathing room, the interval that is central to Japanese spatial philosophy — and the difference is immediately felt. A room with fewer things is not an empty room. It is a room where the architecture can speak. On how Danshari and ‘less is more’ are natural partners, read our article on the principle of Taru wo Shiru (足るを知る).
This is also where danshari connects to material choices. A few carefully selected materials — oak, lime plaster, stone — read with far greater clarity when they are not competing with a room full of objects for the eye’s attention. Restraint in possessions and restraint in material palette reinforce each other. We explore this relationship between material discipline and spatial calm in our article The Secret Behind Japanese Interiors.
The extension that seemed essential may still be needed. But its brief will be different — shaped by what the client actually requires rather than by what they have accumulated. We have seen kitchen extensions halve in scope, and joinery briefs reduce from twelve pieces to six. The architecture becomes more precise, the budget more focused, and the result more calm.
Before You Extend, Subtract
Danshari is not a decluttering programme, and we do not currently offer it as a service — though increasingly we wonder whether we should. What we do offer is a design process that begins with honest questions rather than assumptions, and that treats the contents of a home with the same seriousness as its walls, floors, and ceilings.
The courage to look honestly at what a home has become — at the accumulation, the redundancy, the things kept from habit rather than love — is the same courage that produces a home worth living in. We write about the importance of assessing your property’s potential before committing to a renovation in our article How to Assess Your Property’s Potential. Danshari is, in many ways, the emotional companion to that practical process.
Before you extend, subtract. What remains will tell you everything you need to know.
