 The properties at the front of the site would typically be bought first, so if news broke of the skyscraper then those owning property at the back of the plot would have little choice but to sell anyway.The funding for skyscraper developments was normally lent by banks, insurance companies, or raised through bonds sold through a specialised bond house, with the latter becoming increasingly popular after World War I.Efforts were made to improve the processes for erecting skyscrapers, largely through the work of general contractors such as Louis Horowitz and Frank Gilbreth, who in turn drew on recent work by efficiency specialist Frederick Taylor.
