Sir Joseph Paxton, The Crystal Palace 1850-51Originally in Chatsworth, England
Queen Victoria's husband Prince Albert, and the Duke of Devonshire's gardener, Joseph Paxton.

• 1848' X 454' feet
• September 1850 to January of 1851
• based primarily on an earlier greenhouse design Paxton used to house the giant Victoria Regia lily in Chatsworth.
• iron, wood and glass was lighter and cheaper than other designs submitted
• The dimensions of the building based on 24 foot intervals were a result of the maximum size of a sheet of glass that could be manufactured at a reasonable cost (49 inches was the cheapest for reliable 16 oz glass).
• Mostly site construction using pre fabricated componets, some of which were cast less than 24 hours earlier. The cast iron columns were tested on site, and on site milling and machine painting included miles of wood glazing bars.
• Even temporary fencing material was designed to be used in the final building so little was wasted. The transept was strategically placed to preserve and temporarily cover the large elm trees on the site. When the building was torn down and moved to Sydenham, broken glass was remelted providing some of the replacements.
