Acutally, what I really mean is that the building will not high enough to suit Taipei 101.
Coverage ratio and building bulk ratio are two factors for development in Taiwan.
Coverage ratio (建蔽率) is the ratio between projected area of building in this base and base area. Coverage ratio = area of sturcture / base area x 100%
Building bulk ratio (容積率) is used for calculate how much building floor area allow to build. Building bulk ratio = Total building floor space/Area of Structure x 100%
So for D3,
The size of D3 is about 3219坪 which is 10622.7m2 (106223) and building bulk ratio is 390%.
So total building floor space you can build is 106223 x 3.9 = 41429.7 m2 (41423)
However, I'm not sure statutory coverage Ratio of D3. But, it should be around 50%.
Therefore, 10623m2 divided by 2 equal to 5311.5 m2 (5312).
So maxium area I can use is 5311.5m2.
And I use all 5312 m2 as area of structure and build a boxy building. So floor space for each storey is 5312m2.
Then 41423 divide by 5312 equal to 7.798 ....
Therefore, it will be only 8 floors high for my building.
In fact, it is just a really rough calculation because I skip a lot of things, but it should give some ideas about the height of this development will come out.
Compare with Taipei 101,
the size of the land is 30277m2 and area of structure is 15138m2,
Therefore, the coverage ratio is around 50%.
The total building floor space of Taipei 101 is 357719m2.
So the building bulk ratio is 11.8. (357719/30277)
(The original building bulk ratio is 630%, but our government want and developers to build the world tallest building so it was added to 1260%. And Taipei 101 uses 1180% which mean 80% is remained.)
Comparing with these two, I think there is not too much thing can do for the height. 150m should be the maxium height if building bulk ratio stay in 390%.
