建築始於對人類的保護，皮層的製作是建築的開始，皮層讓自然的空間轉換為人造的空間。皮層是個具有高度活躍性的邊緣，其重要性在於它作為「對話」，內外可以相互滲透並產生多種關係。它有著精巧的設計讓不要的阻絕於外，讓彼此需要的自由流通，也能傳遞訊息。皮層和其所圍塑的空間共享生命，同時枯榮，如同細胞膜和細胞質的關係一般。
皮層最簡單的形式是一扇功能適切的窗，也可以是一面可翻轉的格柵、一層可濾光的擴張網；它也可以是一個空間，比如一個可供活動的陽臺空間、走廊或是騎樓。具有自主性的皮層，就會有引人入勝的美。

Architecture had its beginnings in protecting human beings. The work of architecture begins with construction of an “outer envelope” for a building, an envelope that transforms natural spaces into artificial ones. This highly active layer is a boundary through which exterior and interior engage in a dialogue as they interpenetrate and generate new relationships. An ingeniously designed outer skin blocks what is unwanted but allows the essential to flow in, while also transmitting information. The outer skin and its enclosed spaces have shared lives, just like the membrane of a cell and its inner cytoplasm.
In its simplest form, the envelope appropriately functions as a window, which may become an adjustable grille or an expanded mesh through which light is filtered. The envelope can also contain spaces such as balconies, corridors or arcades where people can gather. An autonomous envelope creates an intriguing new kind of beauty.
