You are not disorganised. You are carrying a whole home
in your head.

Twenty years designing rooms for human performance taught me one thing. The heaviest room is the one no one can see. The mental load you carry from the moment you wake is real, it is heavy, and it belongs somewhere outside of you. OCA is the first place it can finally live.

The research behind this work

This is not opinion. This is proof.

What you feel in your home is not in your head. Three decades of peer-reviewed science explain exactly why your environment shapes your nervous system, your capacity, and your day.

1927

The brain cannot let go of an unfinished task. It keeps a small light burning on every open loop. That is why you cannot switch off at night.

Bluma Zeigarnik · Berlin, 1927

2025

Mothers carry 71% of the household mental load regardless of income or seniority. Earning more does not move it. A promotion does not move it. It has been proved.

Hospital patients with a window view of trees went home a full day earlier and needed less pain medication. Same surgery. Different room. The environment is never neutral.

OCA · the first structural solution

The first place the load
can live outside of you.

Every other app was built for someone already organised. OCA was built for the exhausted mother carrying everything in her head, around how her brain actually works, so the day feels calm and shared, not survived.

In every family there is one person holding the whole day in their head. The appointments, the swimming bag, the bin night, who fed the dog. OCA is where that all finally lives, outside of her.

The cost of waiting

Every week without a system is another week carrying it entirely in your head.

The exhaustion you feel on Sunday night is not random. It is the weight of hundreds of open loops with nowhere to live. The founding women are already building the system. The ones who wait will pay more and start later. There are 300 spots. August 2026. That is the window.

How this work began

Same children. Same teachers. Same curriculum. Different room.

Twenty years ago I designed a classroom for neurodivergent children. The teachers documented measurable changes in regulation and behaviour. I had not changed the children or the teaching. I had only changed the room. That principle runs through everything I now build: the environment is co-regulating the people inside it, every hour. So you may as well design it to work for you on purpose.

The Book

Creating Healing Spaces for Children

Twenty years of designing learning environments for children, including award-winning facilities for neurodivergent students, distilled into a practical, evidence-based guide for educators, parents, and anyone who shapes the spaces children grow up in. Draws on research from Harvard, the University of Salford, and two decades of in-classroom observation.

The minimum cost of replacing one senior woman. The mental load is the hidden variable behind every retention crisis and every leadership pipeline that never shifts.

Helpful advice for designing children's spaces

"A fantastic resource for parents wanting to design a healthy space for their children. My children are 10, 3 and 1 and I still learned quite a lot from this book and have already made some changes to my children's rooms as a result. A great easy read and easy to implement simple changes."
