Keep the design simple and uncluttered.
Be resourceful with inexpensive tiles by creating a border using two sizes or versions of matching tiles, laminate or hardwood.
Expand wall treatments from counter to ceiling.
With neutrals use unexpected combinations: grey with a selection of pink from pale to a deep rose and with beige a selection of blues, just make sure that the undertones are the same.
Define perimeters with borders of plants, an open shelf unit or a screen where there is no wall.
Add mirrors for addition light and reflection.
Add an outstanding architectural element.
Add a piece in black such as a lamp or an ottoman to ground the look.
