The house is from NH 4 lot 4 and the DT is from NH 3.

You can put these lots in any NH you'd like.

Where to put these lots.
For the house lot you unzip it to userdata 1-8, houses, in the sims file of the maxis folder.
You can also unzip it in to the import file of the userdata folder, in the sims file of the maxis folder.

As for the DT Lot.  You unzip it to either the import file (userdata folder) or unzip it to any export 
file in the userdata 1-8 files, in the sims file of the maxis folder.
