Shall you looking for ideas to make your living room visually sizable, here are some tips for you.
First of all, make sure all your main elements like wall, floor tiles and plaster ceiling in the same white or light tone colours while have a black or dark grey TV backdrop. This will make the living space appear more three dimensional and create visual depth to the area.
Secondly, while many designers will advice having mirror panels to doubling the adjacent space visually, you can opt for reflective colour glass panel that has similar colour to the TV backdrop to achieve the same effect while maintaining the intact colour scheme.
Next, make good use of spot lightings under wall shelving or ceiling to highlight certain spots like tv cabinet, display shelving and decorations. The impact of lighting beam and its shadow effects will blurring the actual space boundary lines.
A carefully blend of Colours and Lights always make Nice Interiors.
