A small nursery with a big roof
This project is a small nursery in Yamanashi prefecture, Japan.The site offers a spectacular view of Mt. Fuji. With some houses and farms spread out in its neighborhood, it creates a peaceful, but at the same time, a bit deserted atmosphere.
The client manages three elderly facilities at the site. They wanted to make a community space for the users of the facility and the local people in the middle of the site where it is surrounded by the three facility buildings. The idea was then developed and specified to create a lounge area for having a tea and a nursery to take care of the children in the local area.
▼ 建筑形态柔美的大屋顶，the roofs with gentle curvature
▼ 屋顶下创造的连续的空间，the roofs creates a sequence of connected space
Located in the center of the enclosed site, the roofs are lightly positioned in various angles, opening towards all possible directions to allow physical and visual approach from anywhere. Gentle curvature of the roofs creates a sequence of scenery, dividing garden, lounge, lunchroom, nursing room and office, while the spaces are still kept connected as one.
Children play around, the elderly take a rest, mothers stand chatting with each other, and cats bask in the sun – there is a place for everyone under the roof. It is designed in hopes that this small nursery creates a core space for the community, like a big tree.
▼ 屋顶的搭建，construct process of the roof
混凝土基脚梁上架设着100x100H型钢搭建的轻钢结构，将不同的房间划分。然后在这个轻钢结构中架设50×50的单板层积材 (LVL)。另外，为了获得足够的刚度，LVL楔入两个9mm结构胶合板之间。弯曲的木屋顶跨度10m，厚度仅86mm，是利用木材易于加工成各种形式和尺寸这一特性建造而成的。 它将创造一个气氛温暖的大开放空间。
A steel portal frame by H-100×100, which stands up from a footing beam of reinforced concrete, sets a boundary between rooms, then a 50×50 laminated veneer lumber (LVL) sits between the steel portal frames. To gain stiffness, LVL is wedged between two 9mm structural plywood. The roof can cover a large span of maximum 10m by just 86mm thickness. A soft and light curvature of the roof is achieved by utilizing wood, which can easily be manipulated into variety of form and size effectively. It thus would create a big open space filled with a warm atmosphere.
