In the first place, the woeful experience in this late heavy visitation hath sufficiently convinced all men of the pernicious consequences which have attended the building with timber, and even with stone itself, and the notable benefit of brick, which in so many places hath resisted and even extinguished the fire: and we do therefore hereby declare our express will and pleasure that no man whatsoever shall presume to erect any house or building, great or small, but of brick or stone; and if any man shall do the contrary, the next magistrate shall forthwith cause it to be pulled down, and such further course shall be taken for his punishment as he deserves. And we suppose that the notable benefit many men have received from those cellars which have been well and strongly arched, will persuade most men, who build good houses, to practise that good husbandry, by arching all convenient places. We do declare, that Fleet Street, Cheapside, Cornhill, and all other eminent and notorious streets, shall be of such a breadth, as may, with God's blessing, prevent the mischief that one side may suffer if the other be on fire, which was the case lately in Cheapside; the precise breadth of which several streets shall be, upon advice with the lord mayor and aldermen, shortly published, with many other particular orders and rules, which cannot yet be adjusted: in the mean time we resolve, though all streets cannot be of all equal breadth, yet none shall be so narrow as to make the passage uneasy or inconvenient, especially towards the water-side; nor will we suffer any lanes or alleys to be erected, but where, upon mature deliberation, the same shall be found absolutely necessary; except such places shall be set aside, which shall be designed only for buildings of that kind, and from whence no public mischief may probably arise.
