Thank you Architect for posting the Balmoral castle plans - I've seen the main block before, but never seen the entire structure (with the ballroom and kitchen block included). Raised a few questions for me. First, was the Ballroom added at a later time? (It seems to be, given the odd angle of the corridor connecting it to the main block).
And also thank you for the early 19th century Windsor plans - copies I've seen previously cut off the large room now labeled "Library" adjacent to the Queen's Drawing Room at the corner where the Queen's and King's apartments intersect. I know that today that room is part of the Royal Library, housed in the entire extending wing. But back in the days when these rooms were actually occupied by monarch and consort, was that room divided into multiple rooms - one being the Queen's Bedroom? The King's suite shows Drawing Room, Bedroom, Dressing Room, and Closet / Writing Room (and with a couple of small closet type rooms behind which likely held his bathroom/ toilet. But plans never show a corresponding set of rooms for a queen (bedroom, dressing room, toilet). Where were those located? Also - what is (and was) located in the rooms above these apartments? Were those staff rooms, family / guest bedrooms, or something else?
