I wrote a post about each of these 4 building materials. The links to those posts are at the bottom of this page.
Whatever construction materials you use for your house, you need think about your choice carefully.
Hopefully, the answer is yes to all of the above questions. If not, make sure you are okay with the extra work and/or cost using your chosen material will entail.
One thing you should be careful about, is using building materials or construction techniques with which the local labor is unfamiliar.
If you get too innovative, you are likely to lose the locals along the way. Certainly, they will not be as interested in trying a new building experiment as you, the northern immigrant. You are in for a shock, if you came to Panama with ego-driven notions of how you would build, once you had moved to paradise, and with labor day rates that are less than half of what hourly rates are up north.
For some of us (I include myself here), this will require that we put our own ego in the “back seat." If you don't, you will face a lot of frustration, cost overruns, and disappointing results.
For me, after a long period of trying get the local builders to do things exactly, precisely my way, I have come to the conclusion that it is just not worth it. Believe me, I have tried it, many times (I am a slow learner). It just does not work. Or if it works, it is not a happy experience for anyone.
There are many wonderful things about the Panamanian people. When taken on their own merits, the people of Panama are kind, peaceful, genuinely warm neighbors, and happy to share their beautiful country with us. However, an intrinsic desire to learn something new, from foreigners no less, is not high on their priority list.
It is my opinion that we expats do best when we accept that fact. When we don’t try to impose our own perfectionism and rigid views upon the locals. Our own culture has certainly made plenty of mistakes, and continues to make mistakes and on a global scale.
Maybe we are being offered this opportunity to compromise a bit, to be less perfectionistic and judgmental . With this attitude well in mind, you can produce an interesting, good quality, project. A project that you can be proud of. And most importantly, you will build your house in a way that will not make enemies of your new Panamanian friends. Those relationships will be a joy for years to come.
