階段を降りると、青々とした竹林に囲まれた空間が広がり、様々なアクティビティが用意されています。屋上には、パフォーマンスやイベント用のガラスボックス、さまざまな座席、ジム、トランポリン、ブランコ、茶室、ダイニングルーム、ダンスフロア、チェスセットなど、さまざまなアクティビティが用意されており、竹でできた「迷路」のようになっています。竹は涼しい日陰を作り、密集した都市環境の中で生物多様性をサポートし、アクティヴィティルームは歴史的に恵まれない地域に社会的・レジャー的な空間を提供します。

MVRDVの設立パートナーであるヴィニー・マースは言います。
「アイデア・ファクトリーは、『老朽化した』とか 『耐用年数を超えた』と思われている建物にも、さまざまな可能性があることを教えてくれます。」「私たちは、既存の建物を利用するだけでなく、一層を追加して利用価値を高め、さらに屋上を緑化して南投の公共空間に組み込むことができました。これは、『超新（hyper-new）』都市である深センが、古い建物を再利用・更新して『新旧（new-old）』に変える段階に入っていることを示しています。」

MVRDVは、深セン市南山区公共事業局と深セン万科開発のためにアイデアファクトリーを設計しました。設計は万科の都市研究所、vaLue Design、深センBowan建築設計研究所との共同作業で完成しました。

MVRDV transforms disused industrial building into a “creative factory” with a green public roof in Shenzhen

MVRDV has completed construction of the Idea Factory, a transformation of a former factory building in the Shenzhen urban village of Nantou that sustainably reusing and improving the building instead of demolishing and rebuilding it. The project contains a mixture of offices for the Urban Research Institute of China Vanke and offices for rent – yet despite this programme, its distinguishing features are public in nature: a stairway cuts its way through the six-storey building, leading to a rooftop with a series of “rooms” enclosed by living bamboo “walls”, offering a variety of amenities and activities.

Nantou has roots as an ancient historic town but is now an urban village of Shenzhen, dwarfed by the skyscrapers that surround it. The Idea Factory is the largest project in a number of renovations proposed by Vanke, all with designs by nationally and internationally renowned architects, which aims to accelerate Nantou’s transformation into a cultural and creative hub.

Rather than demolish and rebuild, the design sustainably renovates a disused factory building, maintaining a piece of Nantou’s history while also having lower embodied carbon emissions than a new building. The building’s original structure has been strengthened so that an extra floor could be added on top to maximise floor area. Meanwhile, the original façades have been removed, with the building’s concrete frame exposed and preserved to show traces of the building’s history. The new façade is set back from the edge of the structure, creating open loggias that wrap around the whole building. These allow for circulation and enable the chance encounters with colleagues that make for a dynamic creative environment.

Facing a small public square on the ground floor, a protruding tube-like structure clad in wood marks the entrance to the public staircase that carves its way through the building. Inside, the staircase is clad in mirrors and festooned with bright neon signs, creating an aesthetic reminder of the early days of Shenzhen’s urbanisation. On the fourth floor, this staircase protrudes out the other side of the building – a chance to take in a view of the surrounding rooftops – before turning and continuing up to the roof.

Upon exiting the staircase, visitors are greeted with a green bamboo landscape packed with amenities and activities. This is arranged to form a bamboo “maze” that divides the rooftop into different rooms, each containing a different activity: a glass box for performances and events, a variety of seating areas, a gym, a trampoline, swings, a tea house, a dining room, a dance floor, and a chess set. This roof makes the project more sustainable both ecologically and socially: the bamboo creates a cool, shaded space and supports biodiversity within a dense urban environment, while the activity rooms provide social and leisure spaces in a neighbourhood that has historically been disadvantaged.

“The Idea Factory shows us the wealth of possibilities offered by buildings that some may think are ‘dilapidated’ or beyond their useful lifespan”, says MVRDV founding partner Winy Maas. “Not only were we able to make use of this existing structure, we intensified its use – adding an extra floor – and wove it into the public realm of Nantou with its green and public rooftop. It shows that the ‘hyper-new’ city of Shenzhen is entering its phase of reusing and renewing old buildings and turning them into the ‘new-old’.”

MVRDV designed the Idea Factory for the Shenzhen Nanshan District Bureau of Public Works and Shenzhen Vanke Development. The design was completed in collaboration with the Urban Research Institute of Vanke, vaLue Design, and the Shenzhen Bowan Architecture Design Institute.
