9. The unexpected failing of the Water thereabouts at that Time; For the Engine at the North End of Tower Bridge, called the Thames Water Tower (which supplied all that part of the City with Thames Water) was out of Order, and in a few Hours was itself burnt down, so that the Water Pipes, which conveyed the Water from thence through the Streets were soon empty. 10. Lastly: An unusual Negligence at first, and a confidence of easily quenching it, and of its stopping at several probable places afterwards; turned at length to a Confusion, Consternation and Despair; People choosing rather by Flight to save their Goods, than by a vigorous Opposition to save their own Houses and the whole City. To all which Reasons must not be passed over the general Suspicion that most then had of Incendiaries, laying combustible Stuff in many Places, having observed divers distant Houses to be on Fire together.

That there shall be only four Sorts of Buildings and no more; and that all manner of Houses so to be Erected shall be of one of those four Sorts of Building and no other. The first and least sort of Houses, fronting By-streets or Lanes. The second Sort of Houses, fronting Streets or Lanes of Note. The third Sort of Houses, fronting high and principal Streets. The fourth and last of Mansion Houses for Merchants, Citizens or other Persons of extraordinary Quality; not fronting either of those former Ways. And the Roofs of each of the first three Sorts of Houses shall be uniform. 3. That all the Outsides of all Buildings in and about the said City be henceforth made of Brick or Stone, or of Brick and Stone together. 5. That the Houses of the least sort of Building, fronting By-streets or Lanes, shall be of two Stories high.... The first Storey Nine Foot high from the Floor to the Ceiling; and the second Storey Nine Foot. That all Walls in Front and Rear (so high as the first Storey) be of the full Thickness of two Bricks at length; and upwards to the Garrets of the thickness of one Brick and a half; and the Walls at the Eves of the Garrets not to be less than one Brick. 9. And for the greater Grace and Uniformity of the Buildings in the high and principal Streets, it is Enacted, That all Houses hereafter to be erected in any of them shall have Balconies Four Foot broad with Rails and Bars of Iron, equally distant from the Ground....
