Joseph Paxton, starts the Great Conservatory or Stove, a huge cast-iron heated glasshouse that is to be the largest glass building in the world, in 1837.

The largest sheet glass available at this time, that made by Robert Chance, is three feet long.

Chance manages to produce four-foot sheets for Paxton's benefit.

The building will be heated by eight boilers using seven miles (eleven kilometers) of iron pipe and will cost over £30,000.

There is a central carriageway and when the new young Queen is driven through, it is lit with twelve thousand lamps.

Generally considered a landscape gardener, Paxton's superiority in conservatory design earns him recognition as an innovative architect.

He had developed an interest in glasshouses while in the employ of William Cavendish, 6th Duke of Devonshire, at Chatsworth, the ducal seat.

The principle of using glass houses is in its infancy and those at Chatsworth were dilapidated.

In 1832, after some experimentation, he had designed a ridge and furrow roof to be at right angles to the morning and evening sun, with an ingenious frame design that admits maximum light—the forerunner of the modern greenhouse.
