宏觀來看，都市如一具生命的複雜有機體，有其生衰興頹；在惡化之前，對症取穴，方能治本。面臨全球暖化與全球化之趨勢，是外在環境給予衝擊，亦是警惕，更是都市重啟的機會。

鐵路地下化，猶如對都市進行手術前之觸媒，此大動作不僅縫合都市之疤痕，並可重新編織都市空間結構，也開啟對都市潛移默化滲透的催化效應。

結，是都市中具活動潛力的節點，有集結、再轉換的交通引導發展意義，伴隨著高密度發展，形成都市中複雜機能的巨大機器。而鄰近結週遭的大片閒置土地，適時的留白，等待新的機會來臨，重想一次，而非為單一開發目的。

第三皮層是一種群體意識，試圖建立在建築層級與都市層級之間可被控制的介面；
第三皮層是一種共同規範，透過系統建立的機制由公共決定其欲維護的集體品質；
第三皮層是一種構造形式，企圖成為協調人造建築與自然環境之間分離的第三者。

從形象來看，結，為強化都市公共集結的連接埠，皮層，則為建築物披上外衣，使之消失，此消彼長，效以針灸之術，以通其脈。

Cities would grow and decay in a long-term way just as complex organisms would be born and dead at a cycle .There might be a precise strategy which is able to discover the symptom within the urban where problems occurred . Facing the trend of the global warming and globalization ,It is the right time and opportunity for urban regeneration while the remarks above are mentioned.

Here are the circumstance and occasion where has a plan of rebuilding the railway into underground in Taichung , Taiwan . Underground railway, is a huge challenge for the urban structure which is steady at the heart of the city for almost a century . However ,it is beneficial for this big-dig not only in the city infrastructure but in the coalescence of the urban spaces once lacerated by the railway .More further ,it can initially create a catalyst which may effect a penetration of the built field from the urban central district.

Urban hub , basically is for the purpose of the Transit Oriented Development , it is the term of current network technology to denote the nodal point where flows from different directions are exchanged and redistributed. Urban hubs of maga-city are those nodes where multi modes of vehicle engage. By the very nature of its connectivity, An urban hub should be a concentrated area of densely built and intensely used to accommodate activities requiring heavy transportation to move large crowd. For the specific moment arriving , we should re-conceptualize about the free lands and bring into the urban hub thoroughly .

Third Skin is an interface built between buildings and the urban. It establish mutual norms are made to maintain the environmental quality through the some mechanism of urban design guidline. It is also a new built form to mediate the segreration of the artifacts and the nature.

Creating a hub is meant to strengthen the built form and mix uses ,building the third skin is to make the built form coexist with the nature. Both are useful means for urban regeneration in the way of sustainable developments.
