Land not free. Kontena vs bricks on a similar footprint the cost won't be much different.

Plus it should be impossible to get approval from authorities left and right. TNB will probably not approve, water also difficult and don't forget majlis perbandaran's rules on structural integrity. Impossible la bro.

Registering it under a temporary structure will solve some of the red tape issues but we need to remind ourselves that the purpose of this project is to create homes that people would live in as a replacement for the traditional houses that are deemed to be unaffordable these days.

As the name would imply, a temporary structure is afterall, temporary. Unless there are loopholes that allow these structures to remain indefinitely or with reasonable timeframs (5 years or so), it is hard to see anyone actually investing in these as their home.

A rental-based business model might solve this issue but again you'll have to charge below the standard rate for traditional apartments/flats and still be able to profit even with the possible relocation costs.
