The next logical step up from a replaceable-parts construction philosophy of objects, such as cars, computers, and guns, is a modularization of buildings themselves. This would make the repair of a facet of a building simply the replacement of its module with a temporary while the module is repaired, or, if the cost of repair is prohibitive, simply replacing the module with a new one. Obviously if such an architectural philosophy like this was so simple with such immediate benefits it would already be implemented. Thus, anyone who wishes to design such a system must meet certain specifications:
- Modules must be able to be constructed out of existing building materials, or materials that are cheaply and easily obtainable in large quantities most anywhere.
- Replacement of modules needs to be cheap in both cost and energy requirements.
- Module interconnection must be future-proof on the scale of at least 200 years.
- Module dimensions must be standardized and generalized to a degree such that one module can be replaced with a completely unrelated module and maintain structural integrity, and such replacements must not affect the functioning of other modules.
