There were several glass manufacturers in this area, around where the Fleet River joined the Thames. For a while a Glass House Alley marked this spot, visible on this 18th century map, at the junction of Water Lane and White Fryers. The area, and many of its alleys, are now covered by an office block.
The overlays that highlight 17th century London features are approximate and derived from Wenceslaus Hollar’s maps:

Glass House Alley, Whitefriars and Blackfriars, marked the site for some years: The Whitefriars Glass Works of Messrs. Powell and Sons are on the old site, now Temple Street.
This text comes from a footnote on a diary entry in the 1893 edition edited by Henry B. Wheatley.
Glass House Yard is east of Water Street in the lower SE quadrant of this 1746 map.
There were glasshouses at various times on both sides of the Fleet river and near the Duke of York's Playhouse. Glass House Alley (north out of Tudor St) still bears witness to them. In 1696 there were said to be 24 glasshouses in London and Southwark, making a variety of glass: looking-glass, crown-glass, flint- and bottle-glass etc. (Per L&M footnote)
