The original OSM height15m is preserved as contradictory evidence. Authored overall crown is approximately20.7m: dome55ft plus separate13ft finial from the mirrored operator-authored Lowland Tropics Gallery brochure;55ft=16.764m and13ft=3.9624m are unit conversions, not millimetre survey accuracy. Relative wall/wing/drum heights remain current-photo proportional inferences, scaled to the dome crown. Rear service heights are uncertain.","National Park Service1971 nomination71000184, downloaded from https://npgallery.nps.gov/NRHP/GetAsset/NRHP/71000184_text and reviewed atp2, describes an elongated octagonal dome, flanking L-shaped wings, brick foundation, wood arches and shingled rigid glass with side-room finials. Its250ft width agrees with the76m mapped span. Current selected Commons2014/front/angled photographs were individually inspected; the1879 original lower dome and postcard were not used as current geometry.","The operator history at https://gggp.org/about/ records the1883 fire and subsequent dome raised6ft. The nearly60ft figure is unsourced secondary description and its finial scope is unclear; the historic LoC guide gives58ft dome, also without specifying finial. The brochure mirror distinctly separates55ft dome and13ft finial; Chronicle2009 first-hand architecture reporting gives68ft dome, consistent with that combined crown. The unavailable original brochure URL/date/page and mirror provenance uncertainty are explicit in dimensions.json; no source is represented as a present surveyed measurement.","The photographs show opaque whitewashed glazing and white-painted wood, represented with the shared warm white trim surface and slightly contrasting stone frame. Restoration architect https://www.argcreate.com/portfolio/conservatory-of-flowers/ confirms annual spring whitewashing. Supported blue-grey window panels appear only on the actual vertical door, dormer and clerestory faces. Curved roof glazing uses closed white solids with a raised wood-rib grid, not a flat conventional roof or transparent sorting-dependent glass.","Both LODs independently preserve the mapped E-plan, central octagonal stepped drum and dome, two curved side rooms with cupolas, curved connecting wings and projecting front vestibule. The low LOD reduces roof sections, fine frame subdivisions, ridge ornaments and panel rows while keeping the principal structural rhythm. Landscaped terraces, palms, flower beds, interior plants and current exhibition fittings are outside the building footprint and omitted."],"source":{"url":"/objects/2ee9a7920112aa4e75f12be589f2a27b4c0ee10fd82885ef59ef95becddd5d51/source.blend.gz","bytes":587671,"sha256":"2ee9a7920112aa4e75f12be589f2a27b4c0ee10fd82885ef59ef95becddd5d51"},"spatialSource":{"url":"/objects/e37c2c7a439fe9fc17b1fc80059b2080145ef06c353421dea0490857e13ccf07/spatial-source.json","bytes":8698,"sha256":"e37c2c7a439fe9fc17b1fc80059b2080145ef06c353421dea0490857e13ccf07"},"preview":{"url":"/objects/5c6931b92415739ba531894873e194ab5c3d9a52f4787daacf4e1871f8016b5e/preview.webp","bytes":12582,"sha256":"5c6931b92415739ba531894873e194ab5c3d9a52f4787daacf4e1871f8016b5e"},"previewDirection":[1,0.7,2],"revision":"ee230840abfc68ffe342c3540b27578b588ee9dd2c8baed19d415b6e57c51b99","publicationRevision":"f19bd0a8385115ef7a6578b9b7fef97395805662e6cb5ad411bb69dbfdbab006","bounds":[-122.4606534,37.7724394,-122.4597955,37.7727897],"approved":false,"materialLibrary":{"schemaVersion":1,"sha256":"7afc40cf0b82b7c3c054f287817be2a37e52192aa734f187f8b20ee3277187dd","url":"/materials/7afc40cf0b82b7c3c054f287817be2a37e52192aa734f187f8b20ee3277187dd.json"},"metadata":"/assets/conservatory-of-flowers/f19bd0a8385115ef7a6578b9b7fef97395805662e6cb5ad411bb69dbfdbab006/asset.json","validation":"/assets/conservatory-of-flowers/f19bd0a8385115ef7a6578b9b7fef97395805662e6cb5ad411bb69dbfdbab006/validation.json"}
