歴史的な文脈に溶け込む

チューリッヒの北東に位置するスイスの都市ヴィンタートゥールは、かつて機械工業と機関車の生産で知られていた。現在では高等教育や文化の先進地となっているが、ヴィンタートゥールにあるロクシュタット地区は、19世紀の産業環境を大切にしており、この地区の建築には、当時の工業建築の特徴である高度なディテールが残っている。

シュミット・ハマー・ラッセン・アーキテクツは、この地域の特性を、文化の中心地として生まれ変わらせるための指針とした。

この地で生産された機関車に由来し名付けられた〈Rocket&Tigerli〉は4棟の建物からなり、一般住宅、学生住宅、レストラン、店舗、スカイバー、ホテルが混在している。

さまざまなプログラムが交わることで1日を通して地域を活性化し、4棟の建物によってつくられる緑のオープンプラザに活気を与えるよう設計されている。各棟はそれぞれ独自のビジュアル・アイデンティティを持ち、居住者の間で、自分が住んでいる建物だけでなく、近隣地域全体への強い帰属意識を生み出している。

強いアイデンティティを持つアクティブな街並み

〈Rocket&Tigerli〉は活発で開放的な地域とするため、人と人との交流が生まれるような魅力的な屋外・屋内空間をつくり出している。

国際的なランドスケープ建築スタジオであるフォクト(Vogt)が設計したマスタープランのデザインをより強化するため、シュミット・ハマー・ラッセン・アーキテクツは、大きな空間と狭い通りの間で起こる出会いについて着目した。これは工業建築の中に自然に存在する空間や区切りからインスピレーションを受けたものである。

4つの建物を使ってランドスケープを縁取ることで、シークエンスによる都市空間が構成されており、店舗やレストランとともに、明るい通路や街路レベルの緑地が、特徴的なアイデンティティを持つ活発な地域社会をつくり出している、居住者だけでなく、ゲストにもさまざまなアクティビティを楽しんでもらえるような街並みである。

住戸のデザインでは、全住戸に角度をつけることで日照を最大限に利用し、将来のニーズにも対応できるフレキシブルな空間となっている。

画期的な木造建築システム

〈Rocket&Tigerli〉は、100mという高さが木造建築の記録を更新したというだけでなく、コンクリートに代わる木造の革新的な建設システムを導入しているという、木材の可能性を示すプロジェクトである。

スイスのインプレニア社(Implenia)とスイス連邦工科大学チューリッヒ校が共同で開発した新システムは、コンクリートコアを木材に置き換えることで、個々の梁の重量を低く抑えることを可能にする。これにより、木造高層建築が可能になると同時に、建築プロセス全体が低炭素化を実現できるのである。

木材は、伝統的にコテージや別荘で使われてきた自然素材であり、現在では建物におけるトータルなエネルギー消費に対する優れた性質が注目されている素材である。
私たちは、木材の美しさだけでなく、技術的な施工の可能性から、積極的にこの素材を取り入れてきた。〈Rocket&Tigerli〉には、今回発表された新しい製造方法により、私たちの素材への想いを現代的なビルに反映している。

〈Rocket&Tigerli〉は2026年までに完成し、入居可能となる予定である。

Design the World’s Tallest Residential Timber Building

Danish architecture studio, Schmidt Hammer Lassen Architects, has won the international architecture competition to design the world’s tallest residential timber building. The winning proposal focuses on creating an active neighbourhood rooted in the area’s historical context.

WINTERTHUR, SWITZERLAND – In the next four years, the world’s tallest residential building with a load-bearing structure in wood, will rise above the ridges in the Swiss city Winterthur, close to Zürich. The 100-metres-tall tower, Rocket&Tigerli, is designed by internationally renowned Danish architects, Schmidt Hammer Lassen Architects (SHL). Working from three focus points, the architects’ winning proposal envi- sions an active and attractive neighbourhood, deeply rooted in the area’s historical context, which offers modern, high-quality housing with maximum inflow of daylight.

Integrated in a historical context

“We approach this project with a great sense of humbleness. It is a big project that will have a signif- icant influence on the community, socially as well as aesthetically. Because of the strong expertise Switzer- land has, when it comes to building in wood, we are particularly proud to be working on this ground-breaking project,” says Kristian Ahlmark, partner and Design Director at Schmidt Hammer Lassen.

The city of Winterthur, Northeast of Zürich, has formerly been known for its machine industry and locomo- tive production. Today, the city has become a progressive place of higher education and culture, but in the Lokstadt area – a city within the city – they cherish its 19th century industrial environment. The architecture exhibits the high degree of detail that characterises the industrial architecture from that period of time. In the development of the project, SHL have identified the qualities of the area as a guiding principle for the trans- formation of it into a beating culture heart.

Rocket&Tigerli, named after locomotives, produced at the site, consists of four buildings in a tight choreog- raphy that mixes regular housing, student housing, a restaurant, retail spaces, sky-bar, and hotel. The wide range of facilities are designed to activate the neighbourhood throughout the day, thus bringing life to the green open plaza, orchestrated by the four buildings. Each building has its own visual identity to help create a strong sense of belonging among the resi-dents, not only to the building that they are living in, but to the entire neighbourhood.

The new timber tower breaks with the original masterplan principles for the development of the site, which prepared the ground for a closed block structure. This was, among other things, one of the reasons why the jury chose SHL’s proposal:

“The overall quality of the project, the wide variation in apartment layouts, and clear organisation and addressing of each of the buildings results in a convincing project. By dissolving the original block structure and integrating the detached buildings a larger façade area is achieved and thus more daylight, as well as a stronger connection to the surrounding environment”, states the jury assessment.

Upon its realisation, the tower will seem like a natural continuation of the surrounding architecture. The façade will be covered in dark red and yellow terracotta bricks combined with details in dusty green; a colour palette that reflects the red roofs and yellow bricks of the historical buildings in the area.

An active neighbourhood with strong identity

SHL’s winning project opens up the area by creating attractive outdoor and indoor spaces that call for human interaction. In the original masterplan, the landscape was designed by international landscape architecture studio Vogt. To support the existing masterplan, SHL was inspired by the spaces and breaks that naturally occur in the industrial architecture in the meeting between large spaces and narrow streets. By using the four buildings to frame the landscape, an urban space is composed by sequences. Together with retail and

a restaurant, bright passages and green spaces at street level will create an active neighbourhood with a distinctive identity. A neighbourhood that invites residents and visitors alike to make use of the different activities.

In the design of the residential units, SHL challenges the classical high-rise typology by focussing extensively on the integration of daylight and spaciousness. This results in apartment spaces showered in daylight with double height. All residential units are angled to make most of the inflow of daylight and are designed with a high level of flexibility allowing the spaces to adapt to future needs.

Ground-breaking timber construction system

The project marks a milestone in the construction of timber buildings – not solely because of its 100 metres, which set the record for residential buildings with a load-bearing timber construction, but also because it introduces an innovative construction system that examines wood as a natural replacement for concrete. The Swiss company Implenia and the Swiss Federal Institute of Technology of Zürich, ETH, have worked together in developing the new system, which allows the construction of taller timber buildings. In the new system, the concrete core has been replaced with wood, resulting in the fact that the individual beam comes in at a lower weight. This makes it possible to build taller constructions while, at the same time, ensures that the entire building process achieves a lower amount of embedded carbon.

The marking of an aesthetic and technical shift

The architecture competition was about examining the architectural possibilities of the new construction system. SHL’s proposal celebrates the structure of the construction itself through architectonic effects, where the wooden beams are highlighted as a distinctive element that gives the residents a sense of living inside the construction.

From considering wood as a natural material, traditionally used in cottages and holiday houses, the material is now being treated with focus on its eminent qualities in relation to a building’s total energy consumption. Innovative construction technologies allow the wood to join the mainstream in the built environment both when it comes to all timber construc-tions, and when it comes to hybrids between timber and concrete con- structions. A trend that the SHL studio is excited about, says Kristian Ahlmark as a final note:

“At SHL it is a tradition to design in wood, which is expressed through on-going projects in Oslo, Dor- drecht, Toronto, and Vancouver. We have always been proactive in our use of the material, not just because of its aesthetic qualities, but also because of the technical construction possibilities it paves the way for. The new production method, presented in this project, brings our love for the material into a modern building.”

SHL has worked with timber buildings as a competency for some time now. Currently, the studio is working on interna-tional timber projects in the Netherlands and Canada and delivered several completed projects with load-bearing timber constructions in Denmark, including Framehouse in Dragør.

Rocket&Tigerli is expected to be completed and ready for residents to move in to by 2026.
