Summary
Chenery’s Masters thesis at VUW asks “How can Aotearoa housing be more autonomous?” through design-led research across two Wellington sites. The theoretical framework integrates Maslow’s (1943) hierarchy of needs, McMurtry’s (2004) Primary Axiom Life-Ground Ethics, Mātauranga Māori/kaitiakitanga, Vale & Vale’s (1975/2000) canonical autonomous house definition (“a house operating independently of any inputs except those of its immediate environment”), and Holmgren’s (2002) 12 permaculture principles. Two autonomous cohousing designs are developed: the Kilbirnie site (urban, 18 inhabitants, flooding/liquefaction-prone) integrating 24kW solar, greywater recycling through constructed wetland, water catchment, and composting toilets; and the Paremata site (16 inhabitants, rural-fringe) where permaculture is viable and 15kW solar was confirmed sufficient for all electrical needs including water heating. A field trip to six NZ cohousing communities — Earthsong (Auckland, ~70 residents), Cohaus, Delhi Village, Quinlan Court, 26 Aroha, Quaker Settlement — generated empirical findings on the importance of greywater systems (and their failure risk), composting toilets, solar PV, permaculture zones, and collective social accountability. A synthesis of 10 homestead case studies (NZ and international) produces a design-derived benchmark: 200m²/person for plant-based food self-sufficiency using permaculture, raised beds, food forests, and beehives. NZ living building precedents include Pā Reo Campus (Te Wānanga o Raukawa, LBC certified: 496 PV panels → 105% electricity, all water on-site, 99.7% waste diverted, 761t CO₂ saved) and Ngā Mokopuna/Living Pā (VUW, 110% embodied carbon reduction, all water collected).
Key claims
- 15kW solar panel system sufficient for all electrical needs and water heating for 16 people at Wellington latitude (~41.3°S), confirmed via Cohaus field trip. Equivalent to ~937W/person installed PV capacity. OT_018
- 200m²/person design-derived benchmark for plant-based food self-sufficiency using permaculture zoning, raised beds, food forests, and beehives in NZ context. Not empirically measured — derived from author’s synthesis of 10 homestead case studies and Paremata design iteration. Thrifty Kiwi NZ achieved 1,000kg food/year for 7 people from 200m² total site (1.7m²/person productive land) with raised beds — sets an extreme-efficiency lower floor. OT_018
- Water catchment + greywater recycling → all water reused on-site in Paremata design; greywater system identified as critical but high-failure-risk component across 6 NZ cohousing field trip sites. OT_018
- Composting toilets (EcoLet/Rota-loo) observed across multiple NZ cohousing communities; sewage creates usable compost; occupant buy-in is a design variable. OT_018
- Pā Reo Campus (LBC certified NZ): 496 PV panels → 105% electricity self-sufficient, all water collected on-site, 99.7% waste diverted from landfill, 761t CO₂ saved. OT_018
- Beehives essential for food productivity: fruit trees produce 3× more fruit with beehive than without (Hannah Moloney, Lutruwita/Hobart). OT_018
Key thesis insights
-
Vale & Vale (1975) canonical autonomous house definition — “a house operating independently of any inputs except those of its immediate environment” (p.7). Chenery operationalises this definition at community scale through cohousing + autonomous infrastructure (solar, water, food, waste). The thesis can cite Chenery as the most recent NZ application of this foundational concept, noting the shift from single-household to collective scale. OT_018
-
McMurtry Primary Axiom as design ethics for self-sufficiency — McMurtry’s (2004) seven Life-Ground Ethics principles provide philosophical grounding for designing against capitalist resource dependency. Principle 2 (means of life must enable life capacities) and Principle 3 (complete set of means: atmospheric, bodily, home, environmental, caring, educational, vocational, social justice) map directly onto SSI indicator domains. Chenery is the first source in the wiki to operationalise McMurtry in an NZ community design context. OT_018

Maslow + cohousing + autonomous design = full basic needs provision — Cohousing meets safety needs (Durrett 2009: residents “never felt unsafe”; Newman 1973: natural surveillance deters crime), love needs (mutual care, shared responsibility), and esteem needs (community roles, skill recognition). Autonomous architecture meets physiological needs (food, water, power, waste). Together they allow architecture to aim at self-actualisation rather than survival. Maximum self-managed sustainable community ~35 people (Southcombe, 2017, p.304) — directly relevant to NI pilot sizing. OT_018
-
Mātauranga Māori as design methodology: kaitiakitanga and site spirit — “Ka mua, ka muri” (walk backwards into the future): understanding site history as design foundation for future generations. Kaitiakitanga frames guardianship of Papatūānuku as ethical imperative — not just energy efficiency but responsibility to mokopuna. Marsden & Henare (1992): “Papatūānuku is a living organism who provides a network of support systems for all her children.” Mead (2016): “The land was shared between the dead, the living and the unborn.” Positions self-sufficiency as an indigenous land ethics obligation, not merely a technical project.

NZ cohousing field trip: collective sustainability requires collective living — Across 6 NZ communities, the key enabling insight was social: “It’s much easier to be green when you are doing it together” (Amanda Garland, Earthsong). Permaculture zoning, chore rosters, shared resources, and structured communication were essential governance mechanisms alongside technology. 40kW solar system serving 54 residents observed at one site. Greywater systems present everywhere but consistently identified as failure-prone. OT_018
-
Occupant attitude as design constraint — Vale & Vale (2000, p.35): autonomous design requires occupants willing to “control, use and repair the systems.” Chicca (2020): “houses should also be designed to be environmental teaching tools.” Field trip: some guests refused composting toilets at Delhi Village. Autonomous architecture is only as functional as its inhabitants’ engagement — the design–governance alignment problem is not solved by technology alone. OT_018
-
Pā Reo Campus and Ngā Mokopuna as NZ living building benchmarks — Both Tennent Brown LBC projects demonstrate what is achievable in NZ institutional construction: 105% electricity self-sufficiency, 100% water on-site, 99.7% waste diversion, 110% embodied carbon reduction. Both integrate te ao Māori design principles alongside the highest sustainability standards, showing that kaitiakitanga-aligned design and technical performance are complementary rather than in tension. OT_018

Permaculture as food landscape methodology for self-sufficient communities — Holmgren’s (2002) 12 principles applied at community scale; 5-zone system (Zone 0 home → Zone 5 wild) as spatial food planning framework; Maramataka (Māori lunar calendar) as Aotearoa-specific gardening/harvesting timing guide; beehives essential (3× fruit production). Permaculture’s three ethics (care of earth, care of people, limits to consumption) converge with McMurtry Principle 3 and kaitiakitanga. Mollison (1988): “We are in danger of perishing from our own stupidity” — urgency framing that aligns with self-sufficiency as civilisational necessity, not lifestyle choice. OT_018
