David Mitchell is a great interior designer, product designer, upolstropher, who with just including flowery textures on the furniture material or walls, makes the place look really nice, cozy, simple but still fancy enough.
His style does not go too deep back in old times. It is like he found a style which suits to every part of time. That style was and will be always popular.
Materials and colors used there are good for the living, products are amazing and shapes are not too sharp. He really knows what he is doing and he discovered how to make a great piece.
