At this wooden A-frame retreat in the Normandy region of France, architect Jean-Baptist Barache designed a home that's both casual and elegant, low-key and surprising. A large central window on one of the end gables of the house is accompanied by a scattering of smaller, square "peek-a-boo" windows. The two windows on the third floor bring light and views into the bedroom, and the window on the first floor fits perfectly into the camouflaged rear door.
