An alternative to the concrete block house in the Philippines – a radically different approach

Share the joy

Philippine concrete block houses, the good the bad and the ugly.  The typical Philippine house is a metal-roofed concrete box exposed to the blistering tropical sun.  The heat absorbed by the thermal mass of the building ensures that the house is uncomfortable all night.  These houses are not too different from the hot boxes prisoners are put in for punishment in movies such as “The Bridge on the River Kwai”.   Indoor air temperatures typically reach 90F or more and rarely drop significantly at night.

So why do people build and live in such houses?  There are good reasons. They are affordable.  Local workers know how to build them.  Concrete block house resist most of the many environmental hazards in the Philippines.  They can be cleaned up and re-inhabited after being flooded, they resist typhoons, insects don’t eat them, they are fire resistant and keep out intruders.   Basically these buildings are sand and gravel reinforced with a little (sometimes too little) cement and steel.

Of course air conditioning can help make life in the concrete house tolerable, but energy costs in the Philippines are very high.  There are ways to help keep concrete houses cooler.  Light colored roofs reflect rather than transmit the heat.  Insulation and reflective foil also can help.  Shading the building so that it is not exposed to direct sunlight is very important.  This can be done with trees and other plantings and/or can be done with architectural details such as louvers and awnings.  We will outline some of those measures in another article.

How about a radically different approach?  Friends of ours who live in Baja California in Mexico saw a house going up which used a concrete foundation a steel framework insulated with thick Styrofoam panels.  This part of Mexico is similar in many respects to the Philippines.  Below we present a series of photos of the construction of the house.  We don’t have many details but we know that many persons building in the Philippines want to avoid the typical concrete block construction and are willing to investigate alternatives.  Hopefully these photos will provide some inspiration.  Unfortunately, we can’t provide more detail except to say that the house was finished, inside and out with parge or stucco, perhaps a sprayed concrete material.

Are these Hilti anchors?

  1. I am interested in this kind of house.
    May I know your direct contact number please.


    • Sorry, no information to share on cost of this type of house. You will have to consult local contractors. Good luck.


  2. Hi Bob, I also saw this in my quest for cooling down my abode. I was thinking I could do something similar for my west facing wall as that is the only wall which gets direct contact from the sun. Since the wall is already there I thought maybe put styrofoam slabs and then pin them down with a cover such as the metal roofing. the other idea was to put the radiant barrier foil and then put the roofing material over it for the south wall… got this idea when I saw a huge building with roofing on the side – I didnt see any form of insulation though – my guess that it was to keep rain from going through the cement. Building is being used as a massage parlor – the legit type. Let me know what you think about the wall ideas. ~ thanks!


    • Noel,

      I am really not sure. Making sure the wall reflects as much heat as possible is good. Can you plant vegetation to shade the wall. This could be trees or a trellis with vines.



  3. Was interested in the alternative building methods as the one shown in mexico.I actually built a house in panama using a similar method except the foam panels called M2 where in 4×8 panels enclosed with wire mesh that was covered in cement sand mix and then plastered ,when dry it makes a very strong concrete wall with insulation properties and does not retain the heat.I believe the product is made by corning,if possible I will use the product to build my home in the Philippines.


    • Thanks for your reply. If you have or acquire photos or other info, please share it with us!


  4. “An alternative to the concrete block house in the Philippines – a radically different approach | My Philippine Life” was indeed a superb post.
    In case it owned a lot more pics this would most likely
    be even better. Regards ,Sheryl


    • Sheryl,

      Thanks for taking the time to post a comment on We agree that more photos of the house in Mexico would be helpful, especially ones of the finished house. Unfortunately, we don’y have a way to obtain them.

      Bob and Carol


  5. I’ve seen numerous constructions with this technique in Florida in the last 15 years. Lease sites for commercial purpose use are the most common. It’s being used for Clinics, retirement homes, public works buildings and even shopping centers. Styrofoam is a very strong material but has to be installed correctly and needs to be encased for protection. Stucco/concrete spray proved to be ineffective, Our company’s drive through service entrance had been “ding” & repaired too many times. Hope they can keep the price low in the Philippines.
