Australian interiors studio YSG has updated a holiday home in Sydney's Palm Beach suburb, layering it with a maximalist mix of colours, patterns and textures.

The 400-square-metre house belongs to a young family who wanted a place to escape during the holidays while still providing space for remote working.

The home's original furnishings were included in the sale but the clients were less than enthused by the nautical colour palette, seashells and model yachts.

"The weathered features and cliched seaside tropes, amongst other things, deterred their visits," said Yasmine Ghoniem, founder and director of YSG.

YSG took cues from the rustic beach clubs of Ibiza and Cancun for the revamp, with a touch of French Riviera refinement to create "a palpably playful mood for entertaining".

The house was given a full overhaul, with worn floorboards sanded back to reveal warmer timber accents while windows and doors were replaced with more slimline versions.

In the sunroom, tongue-and-groove panelling was removed for a more contemporary look while a mirrored wall was taken out because it caused the room to overheat.

A new rose-tinted marble floor extends to skirting height, amplifying the sense of space while helping to keep the room cool. In the kitchen, YSG added a stone island "that recalls the ombre shades of a freshly poured tequila sunrise".

The couple also asked for a second master suite, so that they could each have their own retreat while working remotely.

"We designed integrated marble and timber desks, enabling both to simultaneously work privately from their rooms whilst enjoying views from the upper level," Ghoniem said.

For the all-important exterior areas, which wrap around the house on each level, YSG provided a material refresh by removing the old heavy paving and weathered grey timber as they distracted from the views.

The pool area now features a chequerboard pattern of tumbled marble cobblestones while the dark blue pool tiles were replaced with a lighter finish and the chrome fence posts were powder-coated in a soft white tone to prevent glaring reflections.

YSG added a playful painting in the living room that acted as a starting point for the home's entire interior scheme, including the colour palette of ochres, yellows, and reds.

Its motifs such as palm trees and fruit are repeated throughout the house across prints and cushions, as well as being hand-painted onto walls and doors.

Even the painting's chequered top border is continued as a hand-painted datum line across the living room to enliven the otherwise plain walls.

Ghoniem also repeated the same device on the side of the raised step that lead to the dining area, "artistically acknowledging a trip hazard".

In the sunroom, hand-painted swirls soften the beams while in one of the master bedrooms, the vertical red lines of a nude painting were playfully continued onto the wall above the artwork.

The rich material palette features many types of marble, including Giallo, Toledo and Tiberio along with honed travertine and French wash walls, while the textiles include linen and kimono silk.

YSG has completed a number of projects across Sydney, including another house in a coastal suburb with tactile finishes and a penthouse for a couple of empty nesters.
