This paper presents the Version 2. 0 design of the 1000 m² Mars Rubber-Glass House, a comprehensive upgrade from the structural feasibility study (v1, June 2024, DOI: 10. 5281/zenodo. 16493055) into a fully specified habitat for long-duration human habitation on Mars. Building on the Design Improvements v2 proposals — increased ceiling height, thermal zoning, radiation shielding, expanded agriculture, energy storage, and crew privacy — Version 2. 0 integrates five major new systems: Closed-loop waste-to-resource cycle converting human excreta, food waste, and atmospheric by-products into fertiliser, water, and chemical feedstocks. Structured crew routines (daily, weekly, monthly, annual) modelled on operational experience from Biosphere 2, MARS-500, HI-SEAS, ISS, and Antarctic stations. In-situ resource utilisation (ISRU) strategy for manufacturing construction materials, propellants, and speciality chemicals from Martian regolith and atmosphere. Medical and psychological support framework informed by confined-environment research. Simulation and validation methodology following the cycle Investigation → Model → Simulation → Validation → Scientific Assessment. The result transforms the Rubber-Glass House from a structural shelter into a self-sustaining micro-civilisation capable of supporting four crew members indefinitely. At an estimated materials cost of approximately 3 M (or ~108 M including transport), it positions the habitat as a serious candidate for early Martian settlement. This work is part of the Mars Rubber-Glass House project series and references the Three-Step Evolution roadmap (DOI: 10. 5281/zenodo. 16540444) and the Mars Field Laboratories paper (DOI: 10. 5281/zenodo. 15455156).
