Then re-post your question with a specifically mentioned condition not to discuss anything beside the asked question or seek a paid advice elsewhere.

Every program will have a learning curve, especially if you want to draw the house in every detail. I've also used SweetHome3D and it had worked great for a free application. The other paid program is probably even better at that. I'd assume you realize that if you don't have an architectural background then your proposed design might need to be extensively re-worked by a qualified architect, sometimes to the point that it might end up just loosely resembling your initial design or have significant alterations. Unless you have a fluidly allocated budget without financial constraints then you'll be able to get everything you want and how you want it. I'd say the usability of such programs is in their ability to give you an opportunity to clearly and easily communicate your needs and wants to the qualified architect which in turn will convert them it into a real, workable design. And frankly If you just want to envision the position of the house, garden etc on your land parcel then the easiest way would be to just hand draw it to scale on a piece of paper or use a drawing tablet.

A test drive is a must, and not just on perfectly smooth roads. In general the unibody based SUV's are considered to be smooth riding vehicles. The reality is that some manufacturers are purposefully tuning their product to ride on the firm side.

Bluescope doesn't produce steel in Rayong. The steel is being imported from elsewhere, mainly Australia, Japan and China. "BlueScope Steel's Rayong facility operates a pickle line, cold mill, metallic coating lines, paint line and recoil line. BlueScope Lysaght was founded in 1988 to manufacture quality coated steel building products at Rangsit in Pathumthani Province." https://www.bluescope.com/about-us/where-we-are/thailand/

There's no such a thing as Colorbond Zacs. https://www.nsbluescope.com/th/en/our-brands/bluescope-zacs/

How's is it relevant to the unknown (at the moment) battery degradation levels after 10 years of service life?

You shouldn't be extrapolating the life of the battery on the driven mileage alone, as is the case with an ICE motor. A barely used or stored electric battery will still be degrading over time, just at slower rate. It degrades with usage and also over time.

Not sure of the benefits of a tyre spray. "First of all, never opt for tyre shine solution as most of them contain petrochemicals and silicone that will disperse the wax protectant infused by the tyre maker leaving the tyre unprotected from natural elements." https://www.tyremarket.com/tyremantra/tyre-degradation-causes-preventive-measures/ From the site above: Tyre Degradation 1. Rubber oxidization 2. Water 3. Pressure 4. Aging 5. Lack of use

The battery depletion rate is still a big unknown. The technology is improving but not nearly as rapidly as the rest of the tech. There's still not enough of verifiable data with big enough data samples to draw definitive conclusions what would happen to an average battery after 10 years of use. It's quite possible that just about every EV car sold today would need to have its battery replaced shortly after its 10 year service mark. Here's the study performed by the entity with a lot of money on the line, as opposed to the manufacturers or fanboy clubs who have their own biases. "...it seems that a car loses around 1% of range a year for the first 7 years or so, but then the rates increase. By ten years of age, cars were down to 82.5% of the original capacity." https://www.nimblefins.co.uk/study-real-life-tesla-battery-deterioration

Mostly agree with the above, minus a small correction. Colorbond is the marketing name of one of the grades of the product. The name of the brand is Bluescope, the Australian company that has a huge metal coating plant in Thailand. As to the Chinese metal. Look for Bluescope first. Bluescope has many shops located throughout Thailand (franchises). They produce roller formed roof sheets, sold with or without insulation. Bluescope competes with the China and Korea derived coated metal, that is normally sold at discount. Bluescope is considered to be the superior product, especially its Colorbond grade. It also sells a cheaper grade of coated metal, called Zacs, which is still a very good product. It has thinner coating protection compared to Colorbond and shorter warranty. The PU insulation does make a huge difference, especially in its thicker forms. The standard thickness is 25mm. Some shops offer thicker options. PU has really good insulating qualities - no condensation to form. It also dampens noise.

And most of it will be re-radiated back into the atmosphere.

If it easily absorbs heat then it would be equally easy for it to loose the same amount of heat at night. Yes, the same way as in the case of roofing concrete tiles. But you're comparing two incomparable things. The concrete slab vs tiles, which have minuscule thermal mass. The concrete slab has enormous thermal mass in comparison, is not exposed to sunlight and is not heated by outside air. The only heat input it might get is on its perimeter which is negligible in comparison to the amount of heat absorbed by roofing tiles.

That would probably be the very common experience with concrete floors all throughout Thailand.

So, concrete has no thermal mass then? And what happens at night then?

Thank you for posting the pictures. But how are they relevant to ground temperatures under the house floor? Not near or outside the walls, not at the perimeter but directly underneath. Are laws of physics being debated here?

I disagree and it's a debatable topic unless there's some related research on the subject. The ground will only be heated outside of the house walls, on their perimeter. The soil temperature under the floor will come into an equilibrium with the underground soil temperature and remain constant. The soil temperature stays in the low 20s at few meters of depth. The other option is to have an elevated floor with the space underneath that is ventilated. There are many houses in Thailand that's been constructed that way. The elevated floor comes with an added benefit of having extra protection from flooding.

But the ground under the house is not heated.

Lots of good info. The only problem is the huge cost of implementation. I have a question regarding floors. Why to insulate ground floors in Thailand? It only makes sense to do in colder climates.

Do you never use detergents on your dishes either? What crevice corrosion are you so concerned about?

Yes, they did. Check out the list of affected vehicles published in Australia: https://www.productsafety.gov.au/recalls/compulsory-takata-airbag-recall/takata-airbag-recalls-list

Most of higher quality car shampoos are wax safe(er), when are being advertised as such. Household and laundry detergents are definitely not.

Many farmers and tradesmen, if not the most, drive around in king cabs. The Double cabs are also popular, especially with tradesmen.
