塔樓高達(dá)555米高，垂直部分由變尺寸的鋁制肋板組成，沿著建筑精致的錐形外形一直延伸至頂峰。

樂天世界大廈造型優(yōu)美，與該地區(qū)的多山地形形成鮮明對(duì)比，體現(xiàn)了韓國(guó)藝術(shù)界傳遞出的現(xiàn)代美學(xué)。大廈的曲度采用銀色玻璃和白色漆皮金屬絲線渲染，與陶瓷和書法的優(yōu)雅相呼應(yīng)。為了充分表達(dá)這種紋理，設(shè)計(jì)團(tuán)隊(duì)選擇在每個(gè)肋板之間間隔10英尺的模數(shù)，并在中間5英尺處使用一條玻璃拼接縫。為了兼顧美觀和環(huán)保，每塊肋板采用對(duì)角線切割，從而讓建筑輪廓更加清晰可見，確保縫隙中不會(huì)積水。

塔樓的基座重復(fù)應(yīng)用其獨(dú)特的曲度，表達(dá)與行人相關(guān)的垂直和水平特征的和諧性。彩釉玻璃圖案逐漸向地面層延伸。進(jìn)入內(nèi)部后，引人注目的9層高大堂呼應(yīng)了塔樓的幾何形狀，放射狀的線條沿著陶土飾面的巨柱和天花延伸。這一關(guān)鍵部分經(jīng)歷了多種材料的篩選迭代：設(shè)計(jì)團(tuán)隊(duì)從一種灰白色的橡木材料開始，并探索過一種深色的木材，最終確定采用具有印刷木材紋理的塑性塑料。此外，團(tuán)隊(duì)持續(xù)關(guān)注木材質(zhì)感的表現(xiàn)，旨在于入口處打造溫馨感與熟悉感；在確定曲狀外形后，這一綜合體大廈憑借精致的飾面緩解了其巨大尺度帶來的壓迫感，歡迎人們前往。

KPF致力于同時(shí)打造建筑的入口層的體驗(yàn)和城市形態(tài)，大樓的優(yōu)雅也給首爾天際線帶來了紀(jì)念性。此外，業(yè)主決定將頂部十個(gè)樓層加入公共用途（包括公共觀景臺(tái)），也邀請(qǐng)城市參與到建筑中來。

The verticals of this 555-meter tower, composed of telescoping aluminium fins, follow the building’s delicate taper all the way to its peak.

Lotte World Tower’s sleek form contrasts the area’s mountainous topography, conveying a modern aesthetic informed by Korean artistry. Its curvature, rendered in silver glass and filigrees of white lacquered metal, echoes the gracefulness of ceramics and calligraphy. In order to communicate this texture to its fullest, the design team chose to employ a 10-foot module between each fin, with a single glass seam at the 5-foot mark. Each fin was cut diagonally for both aesthetic and environmental purposes, allowing more visibility of the profile and ensuring that water would not pool in its crevices.

The tower’s base reiterates its unique curvature,expressing the harmony of its vertical and horizontal features while relating to the pedestrian.The frit glass pattern expands in a gradient toward the ground level. Moving inside, the dramatic,9-story lobby echoes the geometry of the tower’s form, in which radial lines follow the terracotta mega-columns and the canopied ceiling. This pivotal component endured several material iterations: the design team began with an off-white oak material, explored a darker wood, and settled on a malleable plastic with a printed wood texture.The team’s continued attention to the quality of wood suggests their interest in applying warmth and familiarity to the entrance; when executed in its curved profile, it welcomes visitors to the mixed-use Lotte World Tower with refined finishes that lessen the enormity of its scale.

KPF’s commitment to craft at both the level of its entrance and the sweeping gesture of its urban form reiterate the tower’s elegance as a monument on Seoul’s skyline. In turn, the client’s decision to earmark its top ten stories for public use, including a public observation deck,invites the city to engage with its architecture.
