It's nice how you have the shutters separating the sitting room from the room with the television. I've never seen a setup like that. This looks so peaceful!
What aspects of your house/apartment makes you feel at home,
The master bedroom makes me feel at home. It is mostly black, white, and grey and is the most comfortable room in the house.
what elements have you added to make it feel "yours"
Black, white, and grey is currently our favorite color combination. I've painted our garage walls grey and doors black to make it feel "ours". Also painted the kitchen cabinets black with stainless steel hardware and added white countertops.
Colours are an easy way to add some character and individualism to a house...cheap too, so can be changed easily.
