Massive T-shaped victorian style library, with dome at the top, 58x42 blocks in width, Go rectangular with a central nave and two flanking wings, Aim for 3 stories minimum. The interior needs tall bookshelves, so give yourself at least 15–18 blocks of interior ceiling height for the main hall. Steeply pitched roofs with dormer windows. Use dark oak stairs for the main pitch and spruce slabs for detailing. Add iron bars as decorative cresting along the ridge. Using lanterns (hanging or floor placed) instead of torches, glow lichen on walls. Add pilasters (2-block-wide deepslate brick columns) projecting 1 block out from the walls every 6–8 blocks along the long faces.
