Flush Doors: Invisible When Closed

A continuous wall with two hidden doors that are almost imperceptible. The door panels are completely flush with the wall surface, with no door frames or architraves; the door surface and wall surface use the same material and finish, continuous and seamless; there is only a straight seam between the door and the wall, three millimeters wide and of consistent depth, identical on all four sides. There are no visible handles or locks, opening by pressing or via a hidden recess on the side. The hinges are fully concealed, completely invisible when closed. Thus, the entire wall reads as a single, complete surface, and only upon close inspection will the rectangles formed by the fine seams be noticed. In the image, one door is slightly ajar, revealing its presence. Avoid: visible door frames and architraves; visible handles and hinges; inconsistent seam widths; color differences between the door and wall surfaces.

一面連續的牆,上面有兩扇隱藏門但幾乎看不出來。門扇與牆面完全在同一個平面上,沒有門框、沒有門套線板;門的表面與牆面使用同一種材料與同一種塗裝,連續無差;門與牆之間只有一道寬度三公釐、深度一致的直線縫,四邊都相同。沒有可見的把手與鎖具,靠按壓或藏在側邊的凹槽開啟。合頁是全隱藏式的,關上時完全不可見。因此整面牆讀起來是完整的一片,只有仔細看才會發現那幾道細縫構成的矩形。畫面中一扇門微微打開,顯示它的存在。避免:出現門框與門套線板、加入可見的把手與合頁、讓縫隙的寬度不一致、讓門的表面與牆有色差。
