There are tons of ideas for interior decoration but the key is to stay specific and know what one really wants to see around the house. Have that firmly established prior to planning the actual buying and setting for the house.
As far as living room is concerned, warm colors tend to be only one way of bringing the cozy feeling. One could use pops of some shocking red which can contrast with cement bricks as well as other furnishings for one exciting and vibrant space. Plush seating could be used for living room too which makes anyone want to just sink in for any casual evening with bright conversation.
In the living room or the bedrooms, some personal touch could also be added like artwork and books which will give the house a homey feel and a unique appearance. A combination of turquoise and grey could be used subtly to add to the feminine and warm effect. A neutral option could be use of geometric pattern over few walls to make them stand out against furnishings f calm colors.
Sometimes decadence tends to be the specific aspect one is after. Many of the people will never own grand piano, though if one does, he should surely make it the focal point within a living room with small furnishings that sink into background.
If there is to be some open floor, it demands creative decor and furniture use. One area rug as well as large and heavy pieces should be there to keep living area distinct and separate from foyer. One coffee table that’s elliptical could be placed in center of a spacious living room. If there is a color scheme which involves white, red and grey that would give a good effect too.
So, there are a plenty of ideas but to be applied on one house. Appear tasteful with what you choose!
