Within a few days of the Fire, several proposals for restructuring the city had been put forward by various leading citizens, including Christopher Wren, Robert Hooke, and John Evelyn. Most of the suggested plans involved restructuring the medieval city's roads into a grid pattern, and were rejected on the grounds that re-parceling all the land would have been too difficult, time-intensive, and costly. Keeping Londoners in the city and salvaging its economy were top priorities, and thus the Act focused on putting straightforward, common-sense building regulations into place as soon as possible. In order to prevent improper construction by over-eager Londoners, the Act included a provision to demolish any new buildings that had been erected without adhering to the Act's regulations. Measures were included to attract workmen to the city, and to prevent price gouging of materials or labour.
