Despite some disadvantages of storey buildings, the advantages far outweighs the disadvantages. Some are enumerated below.

(1) Extra height gives good view, distinct and clear view from surrounding structures unlike one floor bungalow that may have been covered with perimeter fence.

(2)The buildings are more visible from a distance to one floor bungalow

(3)Distinct separation of private area from public area. For a two storey duplex, the bedrooms are taken up while the living rooms that are accessible to visitors are left downstairs, this is good for privacy and less noise around the bedrooms.

(4)Security-You can isolate the upper floor from the ground floor with a security door by the staircase in case of any attack. Burglars can’t easily access the upper floor through the windows. It also gives you a clear view of in case of any intruder lurking around the fence.

(5)Interesting features-Storey buildings can be interesting, climbing through a well designed staircase looking at the structure in whole can be quite pleasing to the eyes.

(6)Better aeration- More space is created for effective air circulation as the upper floor create rooms for additional rooms and windows and are most unlikely to be blocked by adjacent walls/fence.

(7)Increase of space-Of course there is far effective use of land space per square meter.

(Storey buildings adapts well to sloped site, a creative architect can design a very aesthetically pleasing building with such soil.

(9)Social Issues- In some clime, it is taken that those on storey buildings usually look down on those downstairs.

1) A well designed single story plan can maximize the topography of the land to get good views. I in fact chose a specific plot that will offer goo views of a valley and will not be building an obtusely high fence.

2) True but you are assuming that the bungalow is sitting behind an obscenely high fence.

3) Not true. A good architect can design a well played out floor plan that creates private and public zones that offers both privacy and shield from noise. If I wanted to be unfair I can suggest that storey houses creates noise for the people downstairs. I you have kids jumping up and down on the second floor, as an example.

4) Not true. You don't defend against robbers inside your house. You destabilize them from entering your perimeter zone by using attack Dogs, security lights, high pitched alarms (sound and strobe to alert the neighborhood), etc Besides you can always employ a safe room of your family.

5) I don't believe that you've seen well designed bungalows. I'll include a few examples below.

6) Definitely not true. It's all about the design. If you have a good design that takes circulation into circulation then a bungalow can be just as effective.

7) Sure, you can build a towering edifice on a half plot. But some of us bought enough land to accommodate a well designed single storey bungalow. You can maximize your space by working with a good architect.

Not true. Goes back to design, again.

9) Perhaps in Nigeria where everything is backwards anyways.

Yes, I love single story building and I am building one soon.

I didn't say storey buildings are better off but has advantages too.
