一支不能動的管，決定了這個家最後好不好住
What you cannot move decides everything you can.
接手這個案子的時候，客變已經做完了。
格局定了，比例卻沒有跟著對：一間臥室被壓得太小，它跟書房、衛浴三者的關係站不住。房間小不一定是房間的問題，通常是旁邊那間佔走了它。
要動的不是房間，是衛浴
所以要動的不是臥室，是衛浴。衛浴整個移位，臥室才長回該有的大小，書房也回到合理的尺度。公共空間後來能那樣放開，起點在這裡。
難處不在牆，在管
移位的難處不在牆，在管。糞管的位置是固定的，動不了；馬桶一換位置，橫管就得找地方走。
走地板最省事，代價是把地墊起來，換來一道要跨一輩子的高低差——而業主要的正是不要那道高低差。所以改用壁掛馬桶，橫管收進牆裡，在牆內接回原本的糞管，地坪從頭到尾是平的。
牆做厚之後，剩下的那段深度
壁掛把牆做厚，是這個解法必須付的。但管線走完之後，牆裡還剩下一段深度。
壁龕與鏡櫃就嵌進那裡——櫃子不再站在地上，它的寬度被收進牆裡。東西收得更多，空間反而看起來更大。一個被逼出來的解法，最後變成這間衛浴最好用的地方。
「一支不能動的管，決定了這個家最後好不好住。」
客變表如果現在攤在你面前，你會先看配備，還是先看牆站在哪裡？
By the time we came in, the pre-handover layout changes were already done: the plan was fixed, but the proportions had not followed, and one bedroom had been squeezed too small. What had to move was not the bedroom but the bathroom. The difficulty was never the walls; it was the pipe. The soil stack is fixed and cannot be moved, so once the toilet shifted, the horizontal run had to find somewhere to go. Along the floor would have been simplest, at the cost of raising the level — a threshold to step over for the rest of your life, and that step was exactly what the owners did not want. So the toilet was hung on the wall and the run buried inside it, returning to the original stack within the wall, leaving the floor flat from end to end. Thickening the wall is what that costs; but once the pipework was in, depth still remained inside it, and the niche and mirror cabinet were set into that depth.
