Brick was once very common to build a house, but as times changed this burnt red material has been used
for aesthetics. So if you are lucky enough to have exposed brick in your
bedroom, then you need to take full advantage of this vintage style. These
days, exposed brick has become extremely trendy and can be found in many high
end lofts in Brooklyn and London, for example. You can either leave this
material in its purest form, as a burnt red, or paint it over to match the rest
of the bedroom, as we see here. A simple coat of white paint creates that
modern, Scandinavian look that the room is going for.
