项目 – LRO建筑事务所为斯图加特1960年代的符腾堡州立图书馆设计的新扩建副楼，在与原有的野兽派建筑实现完美融合的同时，打造出崭新的城市大道与地标。其新添的2万平方米附楼延续了原建筑的原始混凝土美学，采用复杂的手工制作木模板来浇铸新的混凝土外墙。这添加了有机的、栩栩如生的质感，与建筑内部的顺滑表面质感形成了出色的对比。四层高的建筑新体量沿原有图书馆线性延伸，直面繁忙的康拉德·阿登纳大街，重塑了庄严的城市边界。中庭在视觉上联通各层，引入柔和的天然光线。一层还设有新的咖啡厅空间，使建筑向城市开放。一层的人行天桥形成主入口,通向一个明亮的双层高大厅,设有查询服务台、展览空间和安检。建筑处处体现了设计师巧夺天工的智慧，如外立面的锯齿状混凝土及铜板装饰，与旧阅览室互相和谐呼应。室内空间则使用了轻质地毯和木材装饰，增添温暖调性。通过对环境、材料和用户体验的精心考虑，设计团队为这个重要的斯图加特设施创造了一个功能性的、引人入胜的新篇章。

团队 –来自德国的 LRO设计团队的历史可以追溯到其创始人Arno Lederer于1979年在斯图加特创立的建筑工作室。1985年Jórunn Ragnarsdóttir加入成为合伙人，1992年Marc Oei也加入成为合伙人。40多年来，事务所稳步发展壮大，现有约50名员工。LRO以其创建引人入胜的空间而闻名，通过丰富的材料和工艺来唤起人们的精神共鸣。事务所不断推动设计创作边界，重视建筑传统，同时保持对设计环境的质疑精神以打造崭新的当代设计形式。采用密集、整体的设计方法，其团队可以从设计竞赛到项目施工保持全程来保证项目落地。随着创始合伙人Lederer和Ragnarsdóttir在近年逐步退出管理层，新加入的合伙人Katja Pütter、Klaus Hildenbrand和Heiko Müller在2021年与Marc Oei一起掌舵，公司更名为LRO GmbH & Co. KG Freie Architekten BDA。新一代领导人在秉承LRO设计卓越的传统的同时，也发挥出自身的独特优势，始终如一地坚持那些将用户体验置于首位的人文主义价值观。 Feature：

Project - The recent expansion of the 1960s Württemberg State Library in Stuttgart by Lederer Ragnarsdóttir Oei Architekten creates a new urban boulevard while seamlessly integrating with the existing Brutalist structure. The 20,300 square-metre annex sensitively continues the raw concrete aesthetic of the original building, with intricate hand-crafted wooden formwork used to cast the new exposed concrete façade. This adds an organic, lively texture, contrasting beautifully with the smooth interior surfaces.

The four-storey volume extends the library’s linear form, directly addressing the busy Konrad-Adenauer-Straße to reform a stately urban edge. An atrium visually connects the levels, drawing daylight into the centre. The ground floor also houses a new café, opening the building to the city. The first floor pedestrian bridge forms the main entrance, leading into a bright double-height lobby with information, exhibition space and access control.

The building’s zig-zagging white concrete façade, with intermittent copper panels, establishes visual harmony with the older reading room. Inside, amenities like light carpeting and wood cladding bring warmth. Through sensitivity to context, materiality and user experience, the architects have created a functional, inviting next chapter for this important Stuttgart institution.

Design Team - LRO has its roots in the architecture office founded by Arno Lederer in Stuttgart in 1979. He was joined in partnership by Jórunn Ragnarsdóttir in 1985 and Marc Oei in 1992. Over the past four decades, the firm has steadily grown into an award-winning practice of around 50 staff.

Known for creating spaces that engage the human spirit through rich materiality and craft, LRO continues to push creative boundaries. The office prizes both architectural tradition and the questioning of existing contexts to forge new contemporary forms. An intensive, holistic design approach sees small teams nurture projects from competitions through construction.

As founding partners Lederer and Ragnarsdóttir stepped back from management in recent years, leadership transitioned seamlessly. Directors Katja Pütter, Klaus Hildenbrand and Heiko Müller joined Oei at the helm in 2021 when the firm became LRO GmbH & Co. KG Freie Architekten BDA. This new generation stewards LRO’s legacy of design excellence, implementing their own vision while remaining true to deeply rooted humanist values that put user experience first.
