CLOSE your eyes and imagine you are on a long-haul flight; now open them. This contemporary steel, glass and timber house might be in Malibu or overlooking the harbour in Sydney, but actually, it is in south London. It belongs to Eric Lanlard, 36, a pastry chef from Brittany – supplier of gateaux to Fortnum & Mason and owner of Savoir Design, which produces extravagant celebration cakes – and his partner, Paul Newrick, who runs an aviation leasing company.

Their detached house, built by architect HM2 in 2001, sits away from the road, behind video-controlled gates: a modern cube approached by a Big Brother-style timber-decked path.

“A change from our last home,” admits Lanlard, in his strong French accent. “We lived for seven years in a tall, Victorian terrace house in Putney. We modernised it totally – but with old houses you always have to start again. When more cracks began appearing, we just got bored.”

Prior to that, the couple had experienced loft living in the penthouse of a converted match factory in Bow. They rather fancied living like that again.

“We decided to look for a plot on which to build,” says Lanlard, sitting on one of the simple Habitat dining chairs, which they covered in brightly coloured velvets. “The week after we put our home on the market, we saw this house in a magazine. We knew we wanted it, just from what we could see of the outside. We would probably have built something very similar to this anyway.”

The 2,097sq ft property cost £1 million a year ago. “We spent two nights unable to sleep, because we couldn’t afford it,” Lanlard admits. Then they discovered that the owner, a developer, was in a rush to move. So they persuaded him to let them pay a deposit, with another six months to complete. It was not until the week before they moved in that they finally managed to raise the money, thanks to the sale of their Putney home.

TO THE front and rear of the cube house are walls of full-height glass doors, which slide back completely, creating a continuous living space between the house and two garden areas. The steel frame of the building is exposed in an atrium, which has a glass roof. Upstairs there are huge windows everywhere, including internal ones – so ubiquitous are these, you have to remember to pull down a blind when you visit the bathroom.

The open-plan living/kitchen area is white, with more white – white on the wall, white kitchen units and even a white grand piano (this extravagant object can be programmed via a CD-rom to play all by itself). A feeling of space is created by the use of limestone tiles that are laid throughout the ground floor and then out to the garden areas. The space-boosting tricks don’t stop there: holes are punched through the steel in the treads of the glass-sided staircase, the glass coffee table and the windows in every direction all help to cast light around the double-height gallery area.

“The perfect place for summer entertaining, weather permitting,” says Lanlard, of the open-plan area running out to the gardens. “We can fit 100 people in here and the gardens, and our dining table, which normally seats 10, can be extended to 18.”

The house has exposed pipework for air-conditioning, underfloor heating, elaborate lighting and a sound system from Bose that provides wraparound music everywhere from tiny speakers. It’s all very hi-tech, but it still feels cosy.

“We wanted it to be warm. It took ages to find contemporary furniture that was comfy, stuff you could sink into without hurting your back,” says Lanlard. Two swivel leather armchairs and a matching plum leather sofa with a curved back did the business, but cost £15,000. “The sofa seats eight people happily, though,” he reveals.

The developer’s style is seen in the bathrooms, with their taupe anthracite tiles, sleek frameless glass shower enclosures, double-ended Bette baths, modern fittings and large cabinets to hide the clutter.

Similar taste is exhibited in the guest suite, which has a contemporary white B&B Italia bed in the middle of the room, floating shelves and jute curtains – “Yes, they’re sackcloth,” laughs Lanlard.

Did they do any work on the house? “We just knocked down a wall between two bedrooms to make a large master bedroom and extended a few walls for our furniture.” One wall was lengthened to fit their big, glass-fronted cabinet. Constructed of nine glass-and-steel boxes, it has remote-controlled lights that change colour inside and help to set the mood on the outside. “It’s our most expensive piece,” sighs Lanlard. “About £20,000.”

Upstairs they laid a violet carpet in the master bedroom and painted the walls mauve. A faux leopard-bedspread adds to the drama. The walk-in dressing rooms are piled with Louis Vuitton luggage.

“I’m the freak who collects Louis Vuitton,” laughs Lanlard, who has lived in Britain for 15 years. Outside, on the gallery, he has hung a horizontal painting vertically. The artist painted one of the panels using a baguette instead of a brush.

Ah, the French influence …

‘Our £20,000 light show’

The dining table may seat 18 and the grand piano play all by itself, but the most astonishing object in the house is the £20,000 wall of illuminated storage cabinets – made up of nine glass boxes. Eric Lanlard (above) says the unit is the pair’s most expensive purchase, but its remote-controlled coloured lighting (below) can be set to suit any mood …
