When it comes to adding character to a lean, clean, minimal scheme, it's all about the details. Simple lines, uncluttered spaces and pared-down colour palettes create serene living spaces and can help Hong Kong's boxy apartments feel larger but (whisper it) minimalism can be dull.

"I hate spaces with all-white walls; you see it again and again," says designer Yu-Chang Chen, founder of interiors company hoo. "I'm a fan of minimalism, but you need to live a minimalist lifestyle to make it work - it's not practical for everyday life."

And it doesn't mix well with children and all the cheerfully coloured toys and paraphernalia that accompany the average primary schooler.

So when the Lai family of four acquired a 2,028 sq ft, all-white apartment in Jardine's Lookout last year they called in Chen and his team, led by designer Arsan Law Wai-san, to remodel the colourless space and give the three bedrooms and public areas much-needed personality as well as extra storage.

"We kept it simple and clean over-all, but we wanted to add character," Chen says.

While the colour palette is dominated by shades of grey sandwiched between crisp white ceilings and pale oak flooring, the hoo team adopted a diverse collection of materials to create unexpected pops of interest. There are striking patterned tiles in the master en-suite shower, an opaque glass-and-steel sliding door into the kitchen ("the Lais' favourite piece," Chen says, demonstrating its soft-closing feature), luxurious white-marble kitchen countertops, stainless-steel splashbacks and two mismatched pink dining chairs to break up the tasteful grey. A large contemporary Chinese abstract in the dining room - a gift - adds a welcome splash of colour.

There's still a lot of white paint but there is now a feature wall in each room, with different treatments to add texture, colour and interest in keeping with the space. The living room has different but complementary treatments on two walls: small, dark tiles behind the television face a hand-painted grey wall behind the sofa (see Tried + tested). One wall of the master suite features fabric-like grey floral wallpaper, while the children's bedrooms each have one coloured wall with hand-painted details and stickers: dusky pink with a funky fairy for the couple's five-year-old daughter and grey with a panel of blue stripes and red stars for their seven-year-old son.

"We didn't want to overdo it in the children's rooms - so many people go overboard with pink and blue," Chen says. "We kept the colour tone clean and the decoration simple; toys and books add colour and interest. The family brought very little with them from their previous place - almost everything is new - but they did bring the children's furniture. We built in the wardrobes and the bookshelves in the boy's room."

Elsewhere, there's more storage behind a wall of discreet white cupboard doors in the dining room and an L-shaped swathe of wardrobes in the master suite. A floor-to-ceiling shelving unit in the study has just one door that slides to reveal a grown-up book collection on one side and children's games on the other.

Immovable structural walls define the living and dining space, so the remodelling work focused on reorganising the bedroom areas.

Chen added extra square-footage by reconfiguring an air-conditioning utilities area to create a new master bathroom. The old guest bathroom is now a dressing area in the master bedroom and the former en-suite and walk-through wardrobe has been turned into a study nook and a family bathroom. The internal walls of both children's bedrooms were moved further into the hall to accommodate built-in wardrobes.

However, Chen wasn't the only person the Lais rang when they acquired their new home. They also called in a feng shui master.

"There were quite a few feng shui requirements," Chen says. "They were mainly related to colour - some black in the entrance, grey in the bathroom and red in the study."

Accordingly, the front door now opens into a small entry foyer created by a floor-to-ceiling cupboard with glossy black doors; there are red chairs in the study; and the family bathroom has been swathed in large grey ceramic tiles.

"We used different tiles from the same range to add texture to one wall of the bathroom and create a subtle feature," Chen says.

Different strokes French artist Assia Bennani hand-painted the living room wall. "We were going to create a cement wall in the living room, but that was expected and this wasn't," says Yu-Chang Chen, of hoo. "We supplied a grey wall and she sponged extra layers of paint over it. Everyone loves the pink." Bennani can be contacted through Marguerite & Gribouilli (14/F, Greendale, Discovery Bay, tel: 6698 0870).
