This little house was built for $2,500
It is 650 square feet plus the lean-to roof over the front porch. In Cebu Philippines.
Floor --- Slab on grade covered in tile.
Walls --- Four courses of hollow block topped with 4 x 8 woven bamboo panels for a total wall height of 10 ft 8 in. Framing and battens that hold the panels are all of coconut
wood. The
concrete blocks will eventually receive parging.
Roof --- Coconut framing with corrugated sheet metal.
There are no ceilings. It is open right to the peak, which can be a little loud during heavy rain. He may eventually install a suspended bamboo panel ceiling as a sound barrier and radiant heat barrier. Average occupant height is usually about 5 feet 4, for adults, so nobody is very close to the hot roofing.
There are interior partition walls.
Some houses like this are 2 story. When the sun is up, it can be quite hot upstairs, but the upstairs works as a good buffer to keep the downstairs cool. School usually starts an hour after sunrise. Many people are already headed to work before that. So there is no reason for anyone to be in those upper bedrooms during daylight hours.
Air flows freely through this house. The panels are very porous. The gable ends are also woven bamboo, so the roof easily ventilates. No attempt is made to heat or cool houses in Cebu, except in upscale homes that may air condition all or some portion of the house. Usually that means just a bedroom.
The tall walls combined with the height of the sloped roof, make it seem very spacious inside.
Temperatures are almost always between 75 and 90 degrees Fahrenheit. It gets dark around 6 p.m. and the temperature is usually in the low eighties by then, which people here find comfortable. So in a well-ventilated house like this, where both occupants have day jobs that keep them away during the hottest times, it's a very comfortable place to live.
The owner did most of the carpentry himself with the help of his daughter and a friend.
He contracted someone to do the floor and concrete block walls. This was his greatest expense, costing a little more than half of the total.
The wall panels cost $2.70 each which isn't bad for a 4 by 8 panel that requires no further finishing.
Interior finishing is a little rough. He admits that he is no carpenter. He has a much nicer house on a distant Island, but both he and his daughter got work in Cebu and they needed somewhere to live. So they built this sturdy but inexpensive house that they will
sell if the economy on their home island improves.

I'm going to eventually build a home for my mother-in-law. I expect it to be very similar to this. She currently lives in an all bamboo and coconut house on stilts, that is about one-third this size.
My cost
should be a little lower, since this man paid top dollar, being in the metropolis of Cebu. Everything costs a little less in the countryside.
I'm searching for
land in areas that aren't quite as hot and steamy. We will plant bananas and other leafy things around the house. There are some
trees that do a lot of side branching, so we may eventually give the whole house natural shade.
I wouldn't find this house to be comfortable In the heat of the afternoon, but ones like this tend to stay cooler than those built to mimic foreign housing styles. It's about the same temperature as if you sat under a shade tree on a hot day. My wife is perfectly comfortable in this situation if our electric fan is on low and pointed at her. Her mother will be quite comfortable. I will build a very small evaporative cooling device in the sleeping area. She typically takes a siesta from about 2 to 5 p.m.

When we build something like this, I expect that only my wife and I will occupy it in the beginning, and we will use it while we build a much more substantial house for ourselves. It will be concrete block and we'll rely on shading and an evaporative cooler, with a very small air conditioner within an enclosed sleeping area. It will be heavily ventilated at night, but sealed up whenever it gets hot.
