Natural light - wonderful stuff; but the advantage of natural light to the home is only part of the story regarding verandahed housing and correct positioning.
That "eco" word that everyone is hanging their hats on, applies much more realistically with a properly proportioned verandahed house.
Take for example the opposite - eaves free, glass riddled boxes they call modern house today (I still remember them in the 50's!) - these so called contemporary minimalist whatevers claim to be eco friendly; but here's the question, how can having huge glass windows pointing almost directly at the sun with no protection whatsoever, be eco friendly? Quick turn on the air con and let's burn some more brown coal.....
A house with functional verandahs offers the true eco friendly option. Being shaded from the sun, it is naturally cool in summer requiring minimal use of the air conditioning and exterior walls protected by the verandahs do not relay heat to the inside of the home therefore not requiring the massive amounts of insulation desperately needed elsewhere etc etc.
