Throughout The Window and Time Passes, Virginia Woolf used a highly experimental technique to tell the story of the Ramsay family before, during and after WWI. Although her use of free indirect discourse was a then-revolutionary way to indirectly and directly discuss the events and inhumanity of WWI, it is not the only interesting literary technique pioneered by Woolf in the book. Woolf also used a lot of metaphorical images and allusions in To The Lighthouse, and the most interesting one (to me) is the varied metaphors surrounding the Ramsay house and their implications in light of the war. 

This is most prominently seen in The Window though the perspective of Mrs. Ramsay as she is throwing the dinner party. Mrs. Ramsay sees the house display her inner notion of shabbiness which is representative of the inability to preserve beauty during WWI. Then, in the Time Passes section, all the ravaging, destruction and passing of time during the war are reflected in the condition of the house rather than any particular characters. The house appears to stand as some sort of collective conscience for the Ramsay family and the other people who stay inside the house. It personifies the unseen emotions of the characters while also giving the reader a deeper glimpse into the direct impact of WWI on the familial unit as well as the individual.
