Modular Prefabricated Housing Assembly Unit Logic

Act as an experienced architect specializing in modular, panelized, and prefabricated residential systems.

Develop a preliminary modular housing assembly and unit logic using the information below.

Planning requirements:

1. Define the proposed prefabrication approach:
   - volumetric modular;
   - panelized;
   - hybrid;
   - kit-of-parts;
   - bathroom or kitchen pods;
   - componentized; or
   - another supplied system.
2. Establish preliminary module or panel dimensions based on manufacturing, transport, lifting, structural, room-planning, and code constraints.
3. Create a dimensional coordination logic covering:
   - structural grid;
   - planning grid;
   - façade grid;
   - service grid;
   - opening grid;
   - finish zones;
   - tolerances;
   - connection zones; and
   - transport envelopes.
4. Develop a unit-family strategy using repeatable modules that can generate multiple dwelling types.
5. Balance repetition with variation in:
   - unit size;
   - bedroom count;
   - accessibility;
   - façade;
   - orientation;
   - entry;
   - balcony;
   - roof;
   - internal layout; and
   - site response.
6. Develop preliminary stacking and aggregation logic for detached, row, walk-up, courtyard, or multi-storey arrangements as relevant.
7. Coordinate wet areas, vertical risers, horizontal distribution, plant, metering, ventilation, and maintenance access.
8. Identify module-to-module and module-to-site interfaces involving:
   - structure;
   - fire separation;
   - acoustics;
   - air sealing;
   - water sealing;
   - thermal continuity;
   - façade;
   - roof;
   - floors;
   - ceilings;
   - services;
   - finishes; and
   - tolerances.
9. Develop a manufacturing-to-handover sequence covering design freeze, procurement, prototypes, factory production, QA, transport, storage, lifting, setting, connections, weather sealing, commissioning, and defects.
10. Identify design decisions that must be frozen early and those that can remain customizable.
11. Include disassembly, repair, component replacement, future extension, and end-of-life considerations.
12. Create a risk register for transport, lifting, tolerance accumulation, water entry, service mismatch, fire stopping, site delay, factory delay, and change control.
13. Do not invent transport laws, crane capacity, structural connections, fire ratings, factory capability, costs, tolerances, or code requirements.
14. Do not certify structural, fire, acoustic, thermal, transport, lifting, or manufacturing compliance.
15. Flag all items requiring architect, modular manufacturer, structural, fire, MEP, acoustic, façade, transport, lifting, logistics, contractor, insurer, and local-authority review.
