^^ As I live in Bali and being a native Balinese, I gave some explanation, ordinary people's view, why most of us, retained our traditional architecture even in remote village.
First, it has to do with regulation. Balinese regulation mandated the Balinese architecture context when designing a building, in order to keep the Bali aura intact. Usually it is done in form of mandated use of stone carving, use of red bricks, statues, and roof. This is much evident on buildings constructed during Old and New Order governments where local architectures are highly valued and appreciated, even on international-style buildings. In reform days, since 2005 and later, the trends shift away from our local architecture to almost puritan neomodernism. Even it did employ some "local" elements in order to fulfill the regulation, I rejected such notion as it feels like in Jakarta rather than Denpasar. For example, Alamanda Tower in Jimbaran and upcoming Crea in Nusa Dua.
Second, it's our own awareness. Any Balinese Hindu temples, local meeting hall and certain buildings built in Bali always assumed any elements of Balinese architecture (even catholic cathedrals in Denpasar and Palasari, Jembrana and a mosque in Denpasar are influenced by local architecture). However, in recent decades, I agree, the architects today are very obsessed with puritanism, has poor understanding on local architecture at all, or even because they used imported item which cost the fortune. In Indonesia, this is the real problem, because the architects and building owner appear to chase prestige to their client over aesthetics. I even found a building designed in totally opposing style: neo-classicism.
And even there is claim that Balinese architecture didn't fit on shop building and small homes (or locally rukan/ruko). Oh, come on, I meant, you can't because you're lazy, right?

Introducing an old Bank Mandiri office at Jalan Gajah Mada in Denpasar, I don't know belongs to which preceding bank (as Bank Mandiri has tons of branches from 1999 merger located close to each other) or who designing this building, but the building exhibits quite an example on applying Balinese-styled carvings on shop-offices or shop-houses. More modern example includes this building in Noja, Denpasar. The carving and redbrick use is really worth considering.

I can use my home as example, as my home uses wooden carving on doors, bought from guys in Jepara, Central Java and carved by hand in my hometown.
Old peasants can build such beauty object, I believe, because they paid fee for certain year for a project allocated by village, or government gave us the village social benefit budget. My daddy is leader of local traditional village and formerly owner of local construction company tasked to restore iconic Ujung Palace and my aunt is architect, who did a local temple in my hometown, so I know how do we preserve local architecture and current state of Balinese architecture. Hope this answer a thread that I wish I can answer when this originally posted, but only realised much later.
