a lot of these NGO people have done so much damage to vulnerable African populations.
a lot of rural African homesteads are usually spaced out - made out of sustainable materials - reed & thatch for roofing, then earth brick - which is cooling.
the latrines are always at least 30m from the sleeping quarters. but of course - some NGOs will come telling the local people that you've been doing it all wrong.

Toilet facilities are lacking in many parts of the world, and "open defecation" – e.g. toileting in a field without the benefit of a dedicated hole / long-drop / pit – is still in use.The study did show positive health outcomes with the new housing over a traditional mud + thatch dwelling.
Given that the new housing incorporated dedicated latrines, harvesting of clean water, and insect-exclusion techniques, it's unsurprising that the new housing outperformed traditional dwellings in health outcomes.
It didn't do a cost-benefit analysis comparing an equivalent investment in e.g. provision of latrines, insect-netting, clean water, or simply providing cash to the participants.
That said, housing in first world countries is generally a significant multiple of annual median income. In the UK, banks typically lend at 3–4 × an individuals salary or 3 × a couple's combined salary, so a single median earner on around £40k could borrow £120k – £160k.
The article notes the pricing is out-of-reach for many people in Tanzania, but it's also not wildly disconnected from salary:housing ratios in high-income economies.
