Style guide: 
Here are few styles that best suit for home staging, with picture examples 
Contemporary: contemporary means living or occurring at present. Refer to current design trends and constantly evolving with the time. Use the latest designs and innovations with modern futuristic or art deco inspired elements. 
Modern: think Bauhaus – the roots are the Scandinavian and German architecture, simple, functional. Use natural materials, earthy colours, white wash walls, patternless fabrics. 
Minimal: simplified contemporary, emphasise the functionalism, clean and airy with square shapes, the beauty of functionalism 
Scandinavian: lots of white, functionalism, natural materials, light woods, innovative designs, sustainability 
Mid-century modern: those popular ‘retro' furniture we all know, square shapes or the Ercole styles, darker woods; lots of brown yellow and dark green. Avoid to use those bold original pattern though, in a big amount can be overwhelming, better if you use lighter, more neutral coloured fabrics on furniture and go bold with few cushions only. 
Transitional style: balanced mix of antique, vintage and contemporary with luxury fabrics, attractive artworks and decorative accessories, well suits for all kind of properties, but important to find the balance, the few focal point and right scaling.
Classical style: elegant, well balanced decorative furniture, antique or antique style, rather dark woods, deep rich colours, lots of soft furnishing, often symmetric arrangement. Classical style can be very appealing, but it is more suitable for period properties, bigger rooms with high ceiling. I would not suggest using in a modern house, seems just out of place and can make smaller place overcrowding with too many decorations, accessories
