The house that I grew up in India, has that lattice as part of the building. Used to be great when I was growing up as the house was on a raised foundation compared to surrounding houses, and we would get a nice breeze in the evenings. The neighborhood was not dense and we mostly had single family homes.

Now, because of the absence of zoning regulations, we have 4 story buildings - so there goes any natural light and ventilation and there is an epidemic of dengue because of mosquitoes.

And that lattice annoys me, will probably need to put a mesh there to keep out the mosquitoes.
