first, clean the home before you move your stuff in, SCOUR IT!!, then at the entrance of the house address the structure of the house and tell it what you want of it, ( to be a place of security, of solitude, of harmonious gatherings, of sanctuary, etc etc) then white dage smudge the rooms individually, THICKLY. Afterwards perhaps a nice summoning spell to summon the spirit of the house( the structure, not a human spirit), maybe using a good Benzoin/ Myrrh combination with whatever other scents you may think are fitting for the purpose you have chosen for the structure, then after proper acknowledgement of the house itself, and respects given, perhaps ( but this is just me) a protection over the house, and a place to set up an alter for the house itself, ( where offerings can be given to the spirit of the home, requests, and spells performed for the benefit of the home spirit).
