If the recipients could only afford a traditional mud + thatch home, the contractors building work was new additional demand, rather than competition against existing builders. Even when first-world funding dries up, knowledge of the design, its features and benefits will remain. It's also cheaper than the alternative single-storey concrete home design, so perhaps generating new construction demand from people who couldn't quite afford the more expensive single-storey stone house but can afford this new design. It's certainly an eye-opening unusual project, but I think it's a net gain for the region, even without a sustained/permanent first-world benefactor.
