St Stephen's Chapel remained largely unchanged until 1692 when Sir Christopher Wren, at the time the Master of the King's Works, was instructed to make structural alterations. He lowered the roof, removed the stained glass windows, put in a new floor and covered the original gothic architecture with wood panelling. He also added galleries from which the public could watch proceedings. The result was described by one visitor to the chamber as "dark, gloomy, and badly ventilated, and so small ... when an important debate occurred ... the members were really to be pitied". When the future Prime Minister William Ewart Gladstone remembered his arrival as a new MP in 1832, he recounted "What I may term corporeal conveniences were ... marvellously small. I do not think that in any part of the building it afforded the means of so much as washing the hands." The facilities were so poor that, in debates in 1831 and 1834, Joseph Hume, a Radical MP, called for new accommodation for the House, while his fellow MP William Cobbett asked "Why are we squeezed into so small a space that it is absolutely impossible that there should be calm and regular discussion, even from circumstance alone ... Why are 658 of us crammed into a space that allows each of us no more than a foot and a half square?"
