Most often, a living room has a focal point like a fireplace or a television set. You can arrange your furniture around your focal point. As you do this, allow some open space for easy access when one walks into the living room. If you have a large area, you can have more than one set of sofas or conversation area to do away with an empty look. You can also use larger furniture for your space.
Place your furniture according to your space requirement. Your living room might be rectangle, square, octagon or triangle. Whatever the shape is, just make sure you have good furniture placement so that the place will have good traffic. You can place your sofa in a diagonal position and you may even experiment the arrangement in different angles. Traffic is very important to make sure that homeowners can move around the place without stumbling into anything. Your furniture pieces should be arranged well to have good traffic. You can place your furniture in right angles for this will make it easier to converse with other people in the area.
Use elaborate window treatments like swags, valances and tiebacks. Use fabrics that are silk, brocade and damask. Trim these with tassels, cords, braid and crystals to add more embellishments. You can also have a stained glass window if you are willing to spend money for it. To get that Victorian look, use decorative mouldings, ornaments, plasterwork and arches for your walls. Arches can create a grand look while plasters and mouldings give that look of authenticity. These things may cost a lot but would certainly give you the look you want. But if you want to save money, you can opt for walls with deep rich colors like red. You may also apply unique wallpapers with metallic or ornate prints.
