"The bigger issue was that the energy demands for the house, which included hot water heating for the pool and hot tub, outstripped the electrical supply we could get on a rural residential build: 400A" Am I the only one who almost spit out his coffee when reading this paragraph?

I feel downright minimalist now with my 120A/120V grid service.

I'm from the US and I was shocked they needed 400A plus propane. We draw more current then you guys because our voltage is lower but still, 200A services are pretty standard for large rural homes.

And 100A isn't unusual, particularly for anything built more than 20 years ago.

My 100 year old house in the US has 100A service- though I'm thinking of upgrading to 200A service to help with Level 2 EV charging.

The whole thing is pretend environmentalism. It starts out with some superficially "green" elements like solar power but eventually throws it all out the window when that conflicts with luxury or desire. In the end they've built a huge, inefficient house with enough embodied energy to power Ghana for a year, only accessible with the family's giant gas-guzzling truck, as depicted.

I doubt most North Americans need a 400A connection. (How much wattage is that? 48kW?) I live in an ordinary single house in a boring suburb in the bay area, and on hottest days, if I have to use the A/C, the oven, and the dryer at the same time, maybe it would push it over ~10kW. Maybe once in a year.

> Bay Area Most places in the US experience much harsher seasons than the Bay Area.

There are places where we waste energy because we're doing dumb stuff: in northern parts of the country, your house should be well insulated and designed for cold temperatures.

Then there are places like Nevada, which are just not suitable for large-scale habitation. "Can we make this monument to our hubris more energy efficient" is kind of missing the point, right?

As someone who lives in the US, yes, 400A is insane.

Using 400A consistently would be insane. Building the capacity to support 400A but using much, much less on average is... prudent, especially when building a house that is remote.

True. For comparison, I have a 60s era 1000sqft house in northern Canada that had a 60A service into a 50A breaker panel up until last year. For insurance, safety and maintenance reasons[0] we upgraded to a 200A service, but for a small house and a 3-4 person family 50A is sufficient provided your hot water heater is natural gas.

[0]: The incoming line was aerial and over the legal span length, so it had been attached to an insulator nailed to a tree halfway between the house and mast. Also the mast was deteriorating to the point that it needed to be replaced anyways and insurance was making noise about not allowing a new policy if it wasn't upgraded to at least 120A. We did a customer pole and went underground to the house. Much nicer aesthetics and I can now turn off a breaker on my side of the meter at the pole to do maintenance.

This reminds me a lot of time I spend reading Dwell magazine a decade ago. Since that time, I've moved past the point where building such a house is impossible for me financially, but I've also moved past the point where such a house is attractive to me. I saved up a lot of back issues of Dwell thinking I'd refer to them when building a dream home, and in a move a few years ago I threw them out. It felt exactly like…

Yeah, it blew my mind that having a pool was so important to someone in a cold place like Canada. We have a pool in Texas and while it was installed with propane heating 30 years ago, the heating has really never been used as it’s not efficient to do so. I can’t imagine how much it would cost to heat a pool in the author’s climate.

I've done this in Portugal, but on a smaller scale and pretty much with only my own labor. I purchased 6 hectares (15 acres) for mid-5-figures. I've built an A-frame studio house for around €10k (excl tools), and installed a 5kw solar system for about another €10k. The house has air conditioning and underfloor heating (water-based, heated using wood from the land). I've also brought a 50-year-old tractor and started…

Which area of portugal is this? I was looking to do exactly the same. Buy a cheap land and build a small house myself. I am just wary or property tax, bureaucracy and construction costs. Would love to read blogpost about your experience on this

I'm in Central Portugal. It is the Gardunha region (known for its cherry growing). Between Fundao, Castelo Branco, and Penamacor.

I don't think property tax is a big deal. Bureaucracy is a PITA, but accountants, lawyers, and architects are cheap. Use them and it'll all be easier, and likely cheaper in the long run.

Construction costs are going up around here. The price I heard 4 years ago was €500-€750/m2 of house construction minimum.

Land should cost around €1/m2, although it will be more if it has a habitable house or is being sold as 'you can build a house here' plot. I got planning permission (via an architect) to build a 300m2 house on an agricultural-only plot of land, although I didn't go through with it. Rules vary by region, but around here you can fairly easily get planning permission if you own more than 2ha of land.

Get in touch if you want to talk more! Email is on my website. (asking questions here is also great)

Leaving out the actual financial information makes this post a little useless. Before I can imagine it, I want to know if I can do this or if I need to be a trust fund baby.

The post says they own a duplex in Vancouver, the most expensive housing market on Earth. This is where your rents are going if you are a family renting a flat in Vancouver for $4500/month: for these people to pave over some remaining BC forests.

Supply is 240V in North America. You probably have multiple 240V circuits at your home, typically for electric range, oven, and clothes dryer at least. It is split into two for regular outlets and lighting.

Very interesting. Here in EU houses usually have three phases @ ~380V, where each phase is ~220V.

US residential service is split phase 120/240, US commercial service is generally 120/208v three-phase or 277/480v three-phase.
