Part of the enjoyment of a work of art lies in appreciating the detail that contributes to the finished piece. A similar kind of pleasure can be taken in a decor where craft skills dovetail with great design.

This master suite, which includes an office, has broad expanses of wall to showcase artworks, such as a piece by pop artist Alex Katz. The design, part of a condominium renovation by Mick De Giulio, includes sculpted walls and ceiling planes that demarcate areas of use and offer an appropriate setting for the paintings.

The wishlist here was for a light-filled space and a gallery-like ambience, says De Giulio.

"As this is an adult space, separating out the bathroom and ensuite wasn't necessary. However, large leather-covered panels can partition the space and a tall headboard on the bed offers a degree of privacy."

Perhaps the most dramatic element in this design, seen from all areas, is the treatment of the bathroom walls. A giant slab of Calacatta Gold marble has been painstakingly cut into myriad brick-size pieces. These form the walls and the ceiling over the shower. With all the tiles from exactly the same source, the tones are highly consistent. Grouting was kept to a minimum to enhance the effect, says the designer.

"The ceilings are also an important aspect of this design. The dropped ceiling over the bathroom includes concealed lighting that creates a floating aesthetic and helps lighten the space."

Beside the shower and in front of the vanity, the ceiling features backlit cutouts in a rectilinear form. This shape is repeated in other areas for example, in the wall tiles and the bench seat that punctuates the shower stall. The cutouts look like skylights and give the impression of a natural light source.

"In general terms, the decor in the master suite is muted to let the art take pride of place," says De Giulio.
