蔡宅村位于松陽縣大東壩鎮，四面環山，石倉溪串村而過。這里已經有兩百多年的歷史，尤其以各種豆腐產品為特色。從前，傳統家庭作坊的制作的豆腐因為環境條件的限制無法達到食品認證的標準，因此銷路并不廣泛。

豆腐工坊的建筑與村莊環境融為一體，順著地形原有的趨勢，從村口綿延向上。工坊在村級成立了原材料和加工戶的合作社，使得傳統豆腐制作工藝的品質得到了提升。工坊的整體運營由合作社完成，村民成為了直接受益人。現在也有不少農戶加入了合作社，收入水平也得到了提升。

“我們村的村民，以前種大豆都是拉出去自己賣，零售，現在工坊建成后由工坊統一收購，方便了村民，價格也抬高了很多。”---村民 闕梅香

工坊的車間功能按照生產的工藝流程沿地形階梯向上。在空間上由原料準備區，磨漿區，煮漿區，炸制區，攤晾區及品嘗區等六個功能區組成。

“工坊豆腐制作的環境條件比家里作坊好很多，做出的產品質量更高。” ---工坊工作人員 孫清根

工坊內的所有生產空間的設計以及設備的選用都達到食品安全檢測的標準，保證了豆腐產品的質量。從而工坊的產品能夠在大城市的超市中售賣，這也使得村莊的整體經濟水平得到了提升。

工坊建起來以后，我們夫妻兩人每天要做兩三百斤豆子，現在收入比前一年增加三四萬塊錢。

建筑的一側設有供游客參觀的通廊，游客可以順著樓梯按順序觀看到豆腐制作的整個過程，最后到達最頂端的品嘗區。這里不僅可以嘗到新鮮出爐的豆腐，也能欣賞到溪水對岸歷史村落的美麗景致。工坊整體采用木裝配結構，在實現現代工坊生產目的的同時，也與村莊內傳統的榫卯結構房屋相呼應。

工坊不僅作為生產空間，同時也是蔡宅村傳統文化和工藝的展示空間。前期，工坊已經接待了幾批學校小學生，參與體驗豆腐的傳統工藝制作。

Location: Caizhai Village, Dadongba Town, Songyang

Completion: 2018.12

Caizhai Village is a traditional mountain village built along both banks of a river over the past two hundred years. The village has always been known for its best tofu production in the

county region. But the products from the traditional family workshops could not fit into current food certificate standards to be able to sell in supermarket.

A new factory is programmed on a linear slope following the river by the village entrance, as a village collective economic entity and to upgrade the traditional tofu production. The building volume is spreading along the slope by six production functions: preparation room, grinding compartment, boiling compartment, deep-frying compartment, drying compartment, and tasting hall. All the production spaces are designed and equipped to upgrade traditional tofu products fitting with food certificate requirements. This will allow the tofu products to sell in city supermarkets and to increase the village economic revenue.

A covered walkway for visitors takes the steps up to observe the traditional tofu making process in sequence, and finally arrive at the tasting hall facing an open plaza to the south

and the historical village fabric across the river. Assembly timber structure system is applied to the building as a modern production factory and also creates a dialogue with the vernacular "tenon & mortis" wooden structure in old farm houses in the village. 

The factory is both production and exhibition space of traditional heritage for Caizhai village. A villager union has been set up to operate the factory to engage family workshops as

shareholders of this collective economic entity.
