A big problem of mine is assuming that people can read my
mind. I realise, yet again, that a lot of the things I have been thinking about
for a sustainable living project have simply never left my tiny little brain.
To the end of airing these ideas, I thought I’d write down what I have been
thinking about for the past few weeks. It centres on a kind of thought
experiment: a row-house complex with four units on a plot of land. Four
families, all living and perhaps working in the complex, and attempting to make
a go of living functionally (if not actually) off grid. The reason for building
a rowhouse complex is pretty clear: when building to a passive house standard,
the money is all in the envelope of the house. That means that building a row
unit saves on insulation of at least one quarter (and at most more than one
half) of the total outer wall area, allowing for more square footage at a lower
per square foot cost. Heating (which would likely amount to no more than
$400/yr for the whole complex based on the passive house standard) would then
be shared through the condo association.
First off, I imagine a lot between 25-100 acres, 50-75%
treed, mainly with hardwoods would be preferable. In my most specific
preferences, those hardwoods would be ash and birch, but I realise I can’t
necessarily be choosy in this regard. The project I am imagining is a
mixed-revenue and rather holistic economic enterprise that does not focus on
any one product, instead it’s meant to produce a number of “crops” while taking
into account the general laziness of the occupants, so the forested portion of
the project is geared toward a kind of slow silviculture. Birch and ash, you
see, have a couple advantages. Both are good saleable woods, but they can also
both be coppiced, which is perhaps one of the most sustainable modes of
forestry around. Coppicing produces the same kind of succession that the
typical forest cycle naturally produces through the occasional fire or
catastrophe, allowing for the meadow-dwelling ecosystem to remain more or less
undisturbed on the land for as long as it is coppiced in a proper cycle. Ash
and birch work well on a 12-15 year cycle, so the forested region would be
divided into 15 and coppiced regularly in sequence. Ashwood makes good poles,
axe (and other tool) handles, longbows, you name it. Both ash and birch can be
tapped. It would allow me to regularly
make the joke to people that “I’d tap that ash”. Just that is worth the lulz.
Clearing would be required for a house, and I have it in
mind to get subdivisible land. One of the things about having a real estate
family is that they are quick to point out the market facts that theory doesn’t
take into account. One of those things is that owning a house that is part of a
housing cooperative instantly makes it both difficult to resell and therefore
drops its market value. I understand that, in theory, housing cooperatives
SHOULDN’T have this saleability problem, and in theory, they are just another
form of house ownership that can be transferred like any other… but in
practice, it don’t work that way. Cooperative housing enthusiasts would be
quick to give me an earful of counterarguments, but my reality is the market. I
would like a multi-family project, but I want it to be a project that is based
on ownership of a whole house and not of a share in a cooperative. Luckily,
condominium ownership is more mainstream and provides the capacity to 1) own a
unit in the rowhouse complex, and 2) have a cooperative vehicle by which the
collective can share access to common areas. This division between personal and
public is key. A member of the project owns a house and through the condo
association owns access to the common land and greenhouse attached to the complex.
My idea calls for a greenhouse to be located on a
south-exposed slope and attached directly to the house. This is because it would
allow for some of the greywater filtration and urine processing concepts that
I’ve already talked about before. Each greywater system would be separate for
each house, so there can be no recriminations about who threw the candy
wrappers in the loo. While I still believe it is possible to edify adults to
the point that they can transcend the tragedy of the commons, it is hard to do
this for unsupervised children. Realism should prevail when it comes to this
kind of systems design. The greenhouse would contain aquaponics systems that
should also run separately, if only for the purposes of sustainability: one
linked system that fails leaves everyone hungry; one of four individual systems
is just a temporary stress on production. Vegetables can be produced year round
in such a system, and fish can be harvested on a routine basis after a year. I
am planning on experimenting with a “bioponics” system here in the Philippines
that requires no fish food inputs to be purchased. If it works, that would be a
substantial savings on traditional aquaponics methods and would integrate food
waste processing into the whole house system. Any organics that cannot be
processed easily in the black soldier fly and vermiculture bins can be pyrolised
for biochar in a biochar gasifier. There are commercial units available that
are virtually fuel-neutral, since running the system from a hopper requires
only propane to start the gasfication process, and continuous processing would
not only not require further fuel but it would heat the greenhouse too. This is
another reason to keep woods other than hardwoods on the lot: fuel for the
biochar gasifier that produces heat for the greenhouse and biochar for the
garden.
Some people have become convinced that what I am interested
in is “farming”. No. It isn’t. Farming is not something I really want to do.
That said, a limited amount of farming would be good to offset food costs and
perhaps create some value-added assets for the project. Farming is simply a
small part of a greater project I am interested in. I am actually more interested in small-scale
manufacture or value-added production. To me, the perfect industry would be a
brewery or cider operation, since it produces so much organic by-product. Mixing this with an oyster and shiitake
mushroom operation would be advantageous, and both are reasonable profit for
work input. Such an operation already exists elsewhere and is tried and tested.
Raising grain would be great if quantities could be adequate for very small
scale brewing. Still, there should be a minimal dependence on any one product,
and the production should move to where the resource is most abundant in any
given year.
I’m painting a lot of blue sky. This is because the end
result is more important than how the project gets there. The end result that
this project aims for is not some kind of anachronistic pastoral dream or a
retreat from society. The aim is sustainability – for sustainability’s sake.
The aim is to have a place where basic needs are fulfilled - food, water,
clothing, and shelter – and the occupants can take several different tacks to
create value for their products and make money enough to cover the stuff they
can’t make themselves. I’m not attempting to re-create an old way of life but –
even if it never gets past the thought experiment phase – moving toward
creating a lifestyle that’s more focussed on satisfying human needs without requiring
recourse to working in an office. Consider this: if you own a car, you’re
paying about $150 per month in gas, $200 per month in car payments and $50 in
insurance. That’s $400 of your after-tax salary, which is about $500 real
dollars. What if you took a $400 pay cut and walked to work? You’d be saving
money, you wouldn’t have the sudden outlays that are occasionally necessary for
cars (and the thousand natural shocks that tyres are heir to). What if we then thought
that way about food?
What if we decided that, instead of enslaving ourselves so
another person can become wealthy from our toil, we just unhitched ourselves
from that treadmill and went happily away to a place where we provided for
ourselves? That’s the idea. Not farming, not some form of country lordship…
just taking care of your needs without getting beguiled by the dollar signs.
