Installation of a toilet seems something that's best done once in place. However, the water supply and plumbing plus additional septic tank will make it one hell of an expensive toilet relative to the cost of the "house". Might be a better plan to install a composting toilet in an outhouse.
Without kitchen and shower though it'd still not be very usable.

 

When you say "Native house" I think of a house made of Bamboo and a Thatched roof ?
Having recently looked at flat pack houses small and large, it is worth looking at whats available on the internet.
I'm not sure of the situation in Philippines, regarding delivery of such items, but its something you might consider, Cheers.

 

Yes, you are right, the idea has been cancelled already.

 

We have one for a temp caretaker at the farm and then built a CR and outside kitchen behind the Nipa; has worked well so far.

 

Actually it is likely you had a lucky escape not buying one of these, my one time neighbour was to buy one and him and I were to spend many hours in this, it was of very poor construction with most of the more rigid structural members being split at the ends where they bang the nails through it, many times I have shown Pinoys the old carpenters tip where you dull the pointed tip of the nail buy reversing it and giving it a tap with a hammer this most certainly helps prevent splitting, but with Bamboo it is better to drill a pilot hole as this does split so easily, the door to this did not fit from day one it was too heavy for the hinges and had no diagonal brace to it and it had to be lifted up when being opened and closed, they do look good when new when coated with the cheapest varnish they use over there which lasts no longer than 3 months.

150 years ago these were well made with no metal fixings at all within them, the fixings then were wooden splines (tapered pegs) these were dried out in an oven to shrink them a little once driven into the fixing holes they would swell up again in the natural humidity and produce a tight joint which were then lashed with rope as a secondary precaution. these were great at withstanding natural disasters with a natural flex to them they would bend in high winds and well able to take earthquakes in their stride, back in these times a lot less lives were lost even during the worst of any natural disasters, added to all this they tend to keep cool and very comfortable to live in. Termites tend to like Bamboo but back in these times they would submerse this in the sea for a couple of days when it was fresh cut for it to then soak up the salt water a natural repellent to them.

So there we have it the Bamboo Kubo housing which all the working classes were to live in, were fairly easy to build, sustainable and very affordable for the people, added to that they were safe to live in during any natural disasters.

Then the Americans were to take over and Feck everything up, it was them that brought over their ideas of a superior construction method? the CHB DEATH TRAP which is the highest contributor to loss of life during any natural disaster, through the years instead of improving on them, today they are now even less structurally sound than ever before, with their skinny unobtrusive pillars and beams they have now which are often no more than 8x5inch to have them sit flush with both the exterior and interior walls, this to me is so unbelievably stupid and they no longer act as a strength component and offer no support to any CHB structure, on many older builds they are often found to be around 16inch square.

 

Proving once again that every topic is an opportunity for one member to inject their America bashing or housing construction complaints. Two for one, bravo.

"Usually, the bahay kubo was built in lowland areas. People in other places built homes more responsive to their surroundings. The Ivatans had their limestone-walled home; the Bontoc had the steep hipped fayu; and the Maranao had the majestic torogan. These are just examples of homes which deviated from the traditional bahay kubo during pre-colonial times."

Drat them pesky American ideas like higher sanitation standards. Who doesn't like epidemics like cholera, smallpox and beriberi. As seems to be the consensus in this thread, toilets are not a thing in a bahay kubo. Was CHB introduced for the purpose of collapsing on people? When introduced, was it easy and cost effective to produce? How many Filipinos owe the livelihood to CHB production and construction? Is there enough bamboo to replace all the CHB housing? Here is a big one, did it allow for indoor plumbing?

Are we to conclude Americans are the cause of

No that's someone intentionally misspelling around derogatory word sensors to troll on others. It is is a you issue, a view into your character.

I have seen no proof CHB has caused a higher ((percentage)) of the population to expire. Mere ballyhooing about collapsed building news articles, while tragic, is not proof they have extinguished more lives than they have saved. It is not proof America is to blame or deserves credit for the current standard of construction.

and don't get me started on that insidious GI sheeting America introduced. How dare we!

 

Unfortunately the honourable member from the potential republic of Jockistan takes every opportunity to turn a conversation into a CHB/"Stupid Filipino" issue and is becoming somewhat of a bof about it. Never mind, in the words of the great Al Murray "If you love someone you must let them go. We love you Jocks, now Foxtrot Oscar!"

 

On doing some internet research into House build construction, I was to come across this site; MRFIXITBALI This being a business run by a Chartered Engineer named Philip John Wilson OBE 1948 to 2024, who happens to have been an Englishman, although much of his information is about the substandard build quality of housing in Indonesia much of what he says relates to the standards to house builds in the Philippines, it was on his site I first read about falling masonry causing most of the deaths in an earthquake, I have copied the exact passage of what I was to read there on his site and will paste this here;

Falling masonry is the main cause of injury and death during earthquakes. After an earthquake, even a small one, it is good idea to check your building to make sure everything is safe.

Here is something else written by him on the subject of skinny Pillars and Beams;

In the past a typical main structural column was likely to be 30 cms by 30 cms square. These days such a column is more likely to be a wide but somewhat skinny 15cms by 50cms so it can be buried in a 15 cm thick wall and hidden from view.

When these wide skinny columns are used there are couple of important factors we need to keep in mind. Firstly a square column has equal strength in all directions whereas a wide skinny column is stronger in its wide direction but considerably weaker in its thinner direction therefore particular care must be taken in how a building is designed. Secondly when a column is only 15cms thick there is not a lot of margin for error and it is far more important that the size of the column, the quality of the concrete and the size and position of the steel within the column are correct (unfortunately this is not always a realistic expectation in Bali).

As for the dimensions of these skinny Pillars most of the examples I have seen there in PH are around 8x5inch = 20cm x12.5cm Pillars of this dimension are worse than useless more of a hazard than an asset to the build quality. Added to this these Pillars are installed after they have built the walls to then be done in short sections of around 4 to 5ft this creates a weakness at the joints, so they end up being no stronger the the CHB's giving little of any form of support to them.

 

My wife was also looking into an inexpensive housing option for her brother while we demolish an older CHB structure and we found these foldable container homes . One warehouse is in Iloilo so not too far, plus delivery is included in the price. I myself think on of the larger bahay kubo's would be the better option.
