Norra Tornen項目在城市建筑師Aleksander Wolodarski 發起但未完成的原有建筑項目的剩余部分之上又添加了兩個建筑立面。每一個立面由不同高度的逐漸增強的單元組成，這既不是板樓，也不是塔樓，不是一種不妥協類型學的演變。相反，該項目強調大型戶外空間的公寓，避免建筑太過普通。

通過一種“弗洛伊德式飛行”理念采用規定的建筑面——充滿激情地擁抱不可避免的事情，去征服和克服最初的恐懼。原垂直部分再次進行水平分隔，給外觀一種單一、均勻的處理：封閉的室外空間和突出的客廳交替形成凹凸不平的表面。帶筋的彩色混凝土加上外露的多色碎石，呼應了粗野主義建筑風格，而這并非偶然。建筑評論家Reyner Banham表示，粗野主義建筑這個詞是Hans Asplund提出的，他是Gunnar Asplund的兒子，在給英國建筑師朋友的信中提到自己工作室同事的設計時使用了該詞。

Norra Tornen采用混凝土預制板——建筑現場低于攝氏5度無法完成混凝土澆筑，而這個工藝解決了這個問題，同時也大大降低了建筑成本。該設計也讓墻和地板的配比接近1不再是不可想象的事情——大部分研發人員很難做到0.5的配比。在建造的公寓遇到獨特布局，多面朝向，窗戶擴大的情況時就可以采用該設計，這對于半年見不到陽光的國家來說至關重要。大部分市中心的樓房建于第二次世界大戰之前，Norra Tornen引入了全新的生活方式，盡可能地讓住戶享用更多的戶外空間（在歐盟公布的空氣質量城市排名中，斯德哥爾摩排名第四）。

The Norra Tornen project started with two inherited building envelopes,the remains of a cancelled project initiated by the former city architect Aleksander Wolodarski.Each a kind of 'crescendo' composition of different heights– neither slab nor tower– prohibit the unfolding of an uncompromised typology.Conversely,the opted program,apartments with an emphasis on large outdoor spaces,prevented too literal a translation of the envelopes into architectural form.

Through a kind of 'Freudian flight forward'– a passionate embrace of the inevitable in order to conquer and overcome one's initial fears– the prescribed building envelope was adopted as a given.Its initial vertical segmentation was complemented by a second,horizontal segmentation that gives the buildings'exterior a single,homogeneous treatment:a rough skin,formed through an alternating pattern of withdrawn outdoor spaces and protruding living rooms.The chosen material,ribbed colored concrete brushed with exposed multi-colored aggregate pebbles,echoes brutalist architecture and that is not by chance.According to architecture critic Reyner Banham,the term brutalist architecture was invented by Hans Asplund,the son of Gunnar Asplund,when referring to a design of his studio colleagues in a letter to his British architect friends.

總圖 Site plan

創新大樓有182個單元，有44平方米的一室公寓，也有頂層271平方米的公寓，大部分是80至于120平方米的兩室或三室公寓。住宅樓還配有影院、派對和晚宴、客房，帶桑拿和休閑區的健身房和一樓零售區。喜力士大樓包含138個配備完善設施的單元。

兩棟樓高分別為125米和110米，是斯德哥爾摩市中心最高的住宅樓。隨著Karolisnka研究所（頒發諾貝爾醫學獎）的建立，斯德哥爾摩北部新區Hagastaden應運而生，是這個城市的標志性場所。然而，最初建筑立面的應用改變了最初的宏大建筑，其設計更偏重家庭生活方式。之前的形式主義結構應用到住宅上顯得格外不一樣……甚至可以說是人文主義。

Concrete at Norra Tornen comes in the form of prefabricated panels– a construction technique that allows work on the building site to continue even below the five-degree Celsius limit which prohibits in situ concrete pouring.Prefabrication also significantly reduced construction costs.This way a design with a wall-to-floor ratio close to 1– most developers would be discouraged by a 0.5 ratio– was suddenly not an unthinkable proposition.The investment could be channeled in creating apartments with unique layouts,multiple orientations and extra square meters of windows– a precious asset in a country with scarce daylight for half of the year.In a city center with a housing stock largely built before the Second World War,Norra Tornen introduces a new way of living which brings together density with the possibility to enjoy outdoor space (Stockholm ranks fourth among the cities with the highest air quality in the European Union).

The Innovationen Tower comprises 182 units ranging from 44 sqm one-bedroom apartments to a 271 sqm penthouse on the top floor,with the majority consisting of two-or threebedroom apartments of 80 to 120 sqm.The residential units are complemented by a cinema room,a dinner room for parties and celebrations,a guest apartment,a gym with a sauna and a relaxation area,and retail space at the ground floor.The Helix Tower includes 138 units,plus amenities.

At a height of 125 meters,and 110 meters,respectively,the two towers are the highest residential buildings in Stockholm’s city center.Located in Hagastaden,a new district in the north of Stockholm developed around the Karolisnka Institute (which awards the Nobel Prize in Medicine),they stand as a gate to the city.However,the manipulation of the initial building envelopes radically transforms their initial implied architecture of monumentality.It gives way to an articulation of domesticity.A once formalist structure comes to house apartments that are surprisingly informal…one could even say humanist.
