1 Chronicles Chapter 22

[1Ch 22:1 ESV] 1 Then David said, "Here shall be the house of the LORD God and here the altar of burnt offering for Israel."

So the first temple was built on the threshing floor of Ornan.

This verse is interesting also:

2 David commanded to gather together the resident aliens who were in the land of Israel, and he set stone cutters to prepare dressed stones for building the house of God. [1Ch 22:2 ESV]

Non-natural born citizens could be appropriated as labor.  I expect they were supported, fed, and clothed, rather than treated as outright slaves, but still.  And who do we have today claiming they are not citizens but mistreated aliens who deserve to be repaid for the injustices done to them.  Perhaps they would see things differently if they realized that what they are asking for is resident alien status in a country they were born in.  They are actually asking for, demanding, to be given LESS than they deserve.

Though David has been prohibited from building the Temple, he gathers huge quantities of materials to be used.

God has determined that Solomon will be a man of rest, and war will not trouble his kingdom.  Remember that David was cursed with violence all his days for his sin with Bathsheba and Uriah. 

David charges Solomon with building the Temple, and also the elders of Israel to help Solomon.
