Here is a question about this article: London's buildings are too diverse to be characterised by any particular architectural style, partly because of their varying ages. Many grand houses and public buildings, such as the National Gallery, are constructed from Portland stone. Some areas of the city, particularly those just west of the centre, are characterised by white stucco or whitewashed buildings. Few structures in central London pre-date the Great Fire of 1666, these being a few trace Roman remains, the Tower of London and a few scattered Tudor survivors in the City. Further out is, for example, the Tudor period Hampton Court Palace, England's oldest surviving Tudor palace, built by Cardinal Thomas Wolsey c.1515.
What is the answer to this question: What, in part, is the reason for London's lack of a singularly characteristic architectural style among its buildings?

So... their varying ages


Here is a question about this article: Windows in all types of buildings were large and regularly placed on a grid; this was partly to minimize window tax, which was in force throughout the period in the United Kingdom. Some windows were subsequently bricked-in. Their height increasingly varied between the floors, and they increasingly began below waist-height in the main rooms, making a small balcony desirable. Before this the internal plan and function of the rooms can generally not be deduced from the outside. To open these large windows the sash window, already developed by the 1670s, became very widespread. Corridor plans became universal inside larger houses.
What is the answer to this question: What aspect of windows generally varied between floors?

So... Their height


Here is a question about this article: By developing commercial centres and routes, encouraging people to extend the area of cultivated land in the country and international trade through its dominions, the state performed basic economic functions in the Empire. But in all this the financial and political interests of the state were dominant. Within the social and political system they were living in Ottoman administrators could not have comprehended or seen the desirability of the dynamics and principles of the capitalist and mercantile economies developing in Western Europe.
What is the answer to this question: What were the types of economies that were being developed in western Europe?

So...
capitalist and mercantile economies
