Many saw the gigantic task of rebuilding the City as an opportunity. Christopher Wren and John Evelyn, among others, submitted designs to sweep away the cramped, winding streets of old London, replacing the muddle of the medieval city with orderly, open avenues and plazas. These schemes were controversial: one would-be city planner, Captain Valentine Knight, was arrested for publishing his his redesign for London. Knight had suggested that King Charles II could raise money from people paying him fees when renting the new houses. Charles was offended by the suggestion that he might "draw a benefit to himself, from so public a Calamity of his people".
Much of the land in the City of London was in private ownership with complicated mix of landlords, tenants and sub-tenants. Cutting across this complex tangle of rights with an ambitious new street plan was not a priority in 1666, when so many Londoners needed to rebuild their homes as quickly as possible. The winding streets of the medieval city were restored in the rebuilt London.
This dense network of streets have guided the future growth of the city, even into the 21st century. It's difficult to build American-style skyscrapers amid the narrow lanes and small blocks of the City of London. St. Paul's Cathedral, rebuilt to the designs of Christopher Wren, still influences London's planning regulations: new buildings must not block certain "protected views" of the cathedral from locations as distant as Richmond or Parliament Hill.
