Choose one environment and invite users with varied bodies, ages, caring roles and access needs.

Minimum, Ideal, Maximum Limits
Define the operating limits of a proposed habitat in terms people and engineers can both examine.
Follow the connections. Choose your direction.
The need worth working on.
Minimum, ideal and maximum are meaningless without saying what is being measured and for whom. A habitat could meet a narrow engineering minimum while leaving people crowded, tired or unable to participate. The venture should distinguish survival constraints, acceptable everyday conditions and the aspirations residents choose for themselves.
What the enterprise could offer.
Develop a requirements and scenario tool for one shared environment, beginning with ordinary facilities or a non-habitable research model. Include space, temperature, noise, privacy, access, workload and service continuity, with each limit linked to evidence or a clearly stated participant preference. Do not collapse diverse people into one ideal user.
People to build with
- Facility and habitat designers
- Prospective residents or users
- Human-factors and engineering teams
A shared-environment requirements workshop
Define each quantity or experience being discussed and separate professional requirements from preferences.
Compare a minimum-service, comfortable and expanded scenario using explicit assumptions.
Ask participants to identify unacceptable trade-offs and the decisions they want authority over.
The first result
A traceable requirements matrix, scenario comparison and list of unresolved disagreements.
What needs to be demonstrated.
Practical pilot
The starting evidence
The catalogue supplies a limits theme within subterranean cities. It does not provide validated thresholds for a specific habitat.
The open question
Which limits apply to the chosen environment and how people's needs interact under constrained resources.
The next measurement
Requirements with clear evidence, unresolved conflicts and user-rated acceptability of each scenario.
Build the means to deliver.
Useful capabilities and resources
- Paid user participation
- Qualified human-factors and building advice
- Transparent scenario modelling
A possible business model
Requirements facilitation and design-review services could help existing facilities and research programmes before any speculative habitat is built.
A leadership decision to practise
Decide who can reject an unacceptable condition and how minority needs remain visible when averages look satisfactory.
People, consequences and decisions.
- Averages can conceal serious exclusion.
- A survival threshold can be misrepresented as a desirable standard.
- Unverified numbers can acquire false authority through a dashboard.
If equality were being designed now...
- What do women want from their environment beyond merely coping with it?
- Which needs are being hidden by an average body, household or working day?
Begin with women's own experiences across bodies, ages, cultures and places. Invite disagreement and choose a practical change together.

From the original suggestion to a working brief.
Original concept from 500 Queens VC NEW Long, slide 16; current context from the September 2026 planning document. This expanded brief and pilot are proposed development, not evidence of an operating enterprise or confirmed partnership.
Original title: Minimum, Ideal, Maximum Limits. The pilot, business model and learning connections on this page are proposed developments of that original idea.
