Chapter 7

This chapter starts with Solomon building his house.  The 2 Chr chapter begins with details of the furnishings inside the temple.  So they do start quite differently.  The first 12 verses are about Solomon's house, and the house he built for Pharoah's daughter.  Then it describes the temple furnishings.

Solomon's own house takes 13 years to finish. 

This chapter gives details of the construction.  I don't see how you could "reconstruct" this place without a lot of knowledge of the architecture of the time.

More details on the furnishings of the Temple.  It looks like Hiram himself was skilled in bronze work and came to supervise the casting of the pillars.

Vs 13 talks about Hiram from Tyre, who was skilled in working bronze.  2Ch also mentions him but I don't think we saw him before.  Huram-abi is mentioned along with Hiram in 2Ch, so they were different men, both from Tyre.  Hiram was a bronze specialist, Huram-abi specialized in all sorts of things.
