There were 3 branches and 2 houses (in the legislative branch) i hope i answered your question.
VA Plan
it was first Madison idea and made to a VA plan but there was some problem
The VA Plan was: "a plan, unsuccessfully proposed at the Constitutional Convention, providing for a legislature of two houses with proportional representation in each house and executive and judicial branches to be chosen by the legislature." This would create a powerful legislature, and one dominated by populous states. The states with lower populations rightfully feared that this would reduce their power to control the laws and operation of the federal government. The plan was applied solely to the lower branch of Congress (the House) and the representation of slave states was settled by the 3/5th Compromise.
New Jersey plan only wanted one house in the legislative branch. One vote per offical per state. The VA plan wanted 2 houses. An upper house or Senate and a lower house the House of Representatives ( the people's house).
James Madison
There are many websites and companies that offer information on VA loan eligibility. Some of these websites that offer information are the VA government website and Military website.
The Senate and The House of Delegates

I am pretty sure that James Madison, The 4th president, wrote the Virginia plan.
Democracy
One of the major problems/differences was that the smaller states were afraid that the larger states would have more power in the government. The discussion concerning if there would be two houses in Congress compared to one brought this out. States like Del were afraid that a southern state like VA who counted slaves as part of the population would have more votes in Congress. In 1790 35% of the population in VA was slave giving them a large population count. The compromise came in the VA Plan where two houses were set up in Congress. The Senate gave each state two Senators and the House was based on population. To eliminate the advantage of slaves in the count each slave was counted as only 3/4 of a person.
