The two homes you see above are of our modern age because we have air-conditioning everything we build has gotten a whole lot bigger and wider back then they did not have air-conditioning they built their homes around that fact they were long and narrow with a ton of windows so that air could come in and cool their homes off. Now in our age the homes are bigger odd shaped with not as many windows because we have air-conditioners so we do not need the window like they did back then we have them for decoration our new age homes are built to block the sunlight and air flow as for operability it may be a bit less than of that in the older home because of their design and our design As for size ours are a lot bigger than theirs they had 875 sf.
