Where would I find a unit like this?

Example powerful multi-point LPG water heater: Rinnai REU-VR1620WG-ASN. I have a very high flow shower that outputs 1 liter per second and this unit will make it steam hot anytime of year with plenty of power to spare.

Sad. Disturbing forest habitat and taking the leaves from the delicate ecosystem is harmful to the forest. Leaves provide weed control, erosion control, habitat, nest material, replenish the soil, and provide many other uses in the forest. Maybe they should think about putting an end to the burning instead. Then they could target a 100% reduction in hotspots instead of just 20%. The forests and the people would benefit far more.

Absolute minimum always upsize water pipes one step to avoid friction loss. And that alone may not be enough. A typical house may need 1 inch or larger pipes at the trunk to handle multiple fixtures simultaneously properly. There are online calculators for this. You don't want when someone turns on a garden hose or flushes a toilet that your shower stops. In Thai houses running 1/2" pipe this is what happens.

PPR for everything is a good choice. Always say no to PVC on all water supply unless you like toxins in the water, brittle pipes that decay in the sun, and welds that give out.

6KW is too weak to have two showers at once unless they are very low flow and hardly warm. A lot of people would find 6KW unsuitable for even one shower. Multi-point LPG can provide ample heat effortlessly like say units from Rinnai. And they draw almost no electrical power whatsoever; 40 watts instead of 6000 watts.

Toilets have integrated traps, you want p-traps on all other drains as shown. All drains need vented, not just the 2nd floor toilet. A single large septic tank will do a better job than a few little ones. And don't forget the drain field.

The purpose of a business is to make a profit, not become a burden to the tax payer. Propping up this failed system only assures a deeper, longer cycle of poverty for these poor farmers who deserve a whole lot more than a measly 500 baht for all their work. As long as the government keeps doing this, farmers will never change to more efficient, profitable, sustainable systems and just fall further behind other countries.

Good. The red faces explaining to the americans shaking their heads and looking at each other in disbelief why the Thai scale for air quality is so ridiculously lenient compared to the US EPA guidelines. And then having to explain why they only release 24 hour averages of air quality instead of reporting how bad the air quality gets. And best of all it will become plainly obvious the americans can see the extent of all the horrible, totally unnecessary burning going on right inside Thailand. Nothing like shining a beacon on this problem and there is nowhere for them to hide or blame.

A 10 year tile warranty is really daft for a roof if one builds a house to build and forget..... 

Please provide a link to the warranty of your roofing tiles.

They look like the same thing as I had fitted

Oh that type! Yes I too have seen those become brittle, crack, and lose their color badly. I wasn't thinking of this type when cement board was first mentioned. There are many shapes and sizes of cement board roofing tiles. SCG is usually the better choice for quality.

Fredob even not seeing the old roof there is a lot of things that stick out that could be an issue with just any type of roof: the shallow pitch, water falling from one level onto the next, and proximity to ground. Even cutting the eaves that close to the fascia may not be allowed. The builder needs to check if these types of things are allowable no matter what type of roof system is used. Speaking of warranties, I noticed top hat mentioned above has a 10 year warranty. The cement board roofs I have seen seem long lasting as well as their color coatings.

I find it strange anyone could be against digital nomads and yet the poll shows 1/3rd are against them. Who cares if they don't pay taxes, DN's draw in money from other countries doing legal work and spend it in Thailand. Compare that to an English teacher who makes money off Thai's and it gets taxed and spent--not as good. And far better than $0 tourists or skint retirees. DN's are best for Thailand because loads of new money pours into the hands of people that need it and it happens without taking anyone's job. Free money, no downside.

That's interesting you can get Tesla's on that web site. However, who is going to pay double or triple the cost of what people pay for the same car in other countries? This is the problem with EV's in Thailand. Almost no one wants them because they jack up the prices to obscene levels and there seems no logical justification for this. Not just Tesla, but all of them. Where is this hidden tariff coming from? Is the petroleum industry behind it?

Wonder boy announced a solar panel roof option for the cybertruck (below photo). But you get merely 25km/day with it. That is why you don't see car makers doing this. More recently wonder boy said he will make fold out solar wings that increase the cybertruck solar charging to 60km/day. So as long as you don't drive over 400km a week maybe an option. Then again, not clear if Tesla will ever be sold in Thailand.

If I were terrified of breathing the outside air and just wanted to stay in an air conditioned room with an air purifier all day I would just move into an old folks home. 

To each his own, but certainly not required. There will be times of the day or year pollution and noise are not a problem. During these times a passive approach may be ideal. And there will also be times pollution and noise are a health hazard. Ignoring the truth and trying to pretend it isn't happening is bad and unnecessary, but sadly commonplace. One can make a home capable of quiet and safe air inside when you need it and in Thailand the chances of that being a god send to your wellness over and over again is just about 100%. Everyone's top 3 priorities of building in Thailand should be to account for:

#1 the pollution

#2 the noise

#3 the weather

In that order. If you don't consider these things carefully, you might find yourself starting these infinite threads moaning about these things. Not considering these things is a very common building mistake, surely over 90 of homes do not properly consider these crucial factors to health and happiness.

There was advice given that is so important it is worth mentioning again. The air quality in Thailand is unhealthy for a substantial portion of the year. This is not a time to say oh whatever and sweep this information under the rug because air pollution is believed to damage every organ in the body.  Most of Thailand is a tropical savanna climate. This means there is a pronounced dry time of the year and during this time months or even half a year can go by without a drop of rain. This is when burning is rampant and bad air accumulates to very grim levels. With air quality monitoring stations we can now see in real time just how dire the situation is since PM2.5 particles are so small they are invisible to the human eye and also very bad to health since they go right through the lungs and into the bloodstream. When the air gets bad visibility diminishes, schools close, airplanes in some instances can't land, hundred of thousands head for the hospitals, the government sprays water in the air in vain, people are told not to exercise, and people die of respiratory diseases. Thailand in our century is not a good place to try to build a passive cooling lifestyle around. Maybe it was before and one day will be again. For now if health is important to you, you need to seal your house tight, turn on the AC, and turn on a hepa air purifier. There is no other way unfortunately.

And there is yet another problem with passive that may well be even bigger--the noise. All the way to the most out of the way spot in the country unnecessary man made noise is extremely high; an astounding variety of noisy loudspeakers pointing at you, modified motorcycles, barking dogs, weed trimmers, and so on--horrendous noise is everywhere. Noise also takes its toll on human health because it over works the brain and denies it rest it needs to replenish. You need a way to not just close the pollution out, but also the noise.

Based on your post it seems this project is well advanced of what you should be doing yourself. Ask the juristic person to recommend a plumber.

It's a start

Cleanup is a doomed strategy. It is impossible to clean up the oceans until the dumping of garbage stops. Every year more garbage than ever before gets dumped in. Don't waste your energy on cleanup that is doomed to fail. All energies should be to stop the polluters. There is going to be another 14 billion pounds of trash dumped in the oceans next year. If you want to make a difference, that is where you start.

Most trash in the oceans used to come from foreign-flagged boats.

Thailand is the 6th most ocean polluting nation in the world. That is bad in itself, but worse considering how small Thailand is to be so high up on this list.

The solution is incredibly simple and obvious yet they managed to miss the mark yet again. Listen carefully folks: as long as Thai's are forced to pay double the price of what EV's cost in other countries, no one wants them. Meddling with charging costs as proposed won't change this and is just a swing and miss.

People do these online these days such as notarycam
