Sooner or later, Balinese architecture will enter the millennial era. Then, what architectural style that matches the use of exposed brick walls ?. Does it have to be a building with traditional and ethnic style that can use exposed brick walls? Not really, actually, any style fits in well with exposed brick wall applications. When in buildings with traditional and ethnic styles exposed brick walls tend to be applied to the entire building. In more modern styles exposed brick walls are only used as accents. The use of exposed brick techniques seems to be a hassle in manufacturing, costs are more expensive, and maintenance is more difficult when compared to ordinary brick walls. But, after completion, all the hassles will pay off completely, because the exposed brick wall will have a very unique, natural, ethnic, and very strong aesthetic accent. Then how long can this material last? Too bad this beauty is not maintained. Hopefully the riset of the Structure and Materials Laboratory Civil Engineering Study Program will contribute preserving Balinese architecture to be sustainable.
