THE PROPERTY

A first-floor apartment in a 19th-century mansion block in central Barcelona. There’s an open-plan living space with a kitchen, dining area, living area and study, which is set in an internal glazed room. The rest of the flat is divided into four bedrooms, five bathrooms and a laundry. Two terraces look on to the communal garden at the back of the building.

LIVING AREA

Located on the first floor of a turn-of-the-century building, the open-plan space strikes that requisite contemporary but convivial balance. Sofas are low and slouchy and there’s a long, rustic table for family meals. A cosy reading nook is framed by pillars recalling the building’s 19th-century roots.

In many ways the apartment is the exact opposite of the traditional Spanish aesthetic, which tends towards moody colours and heavy textures. This interior is a fusion of influences – Scandinavian, industrial, bohemian – absorbed from all over the world.

The space has been painstakingly transformed from two separate pokey apartments full ofsmall, dark rooms with damask wallpaper, wood beams and chandeliers – typically bourgeois Spanish – to light and airy oasis.

The interior designer, Marta Castellano, worked closely with local architects Enric Serrat and Albert Tort to unite the two flats. Out went the light-guzzling partition walls; granite pillars and beams were painted white; and the worn and stained parquet flooring ripped up, painstakingly renovated then painted.Now light pours into the 300sq m of space.

This flat has minimal possessions, and is all about space, luminosity and tranquility rather than objects.The less is more aesthetic stretches to every detail –the large white panel, for example, is a period roof tile discoveredin an antiques market in Girona.

Throughout the apartment, the original oak parquet floor was painted white to enhance the low-key mood.

The space is designed so that all the key living areas lead to the terraces at the back of the flat – it adds to that easy living feel.

There is no technology on show in the apartment. So, instead of a TV, a projector and pull-down screen is tucked above the study.

The space is a mix of vintage finds; apleasingly scruffy armchair is Belgian; the linen-clad designer sofa is Dutch; a vintage roof tile became an artwork

READING PLATFORM

The reading platform and black window frames work together to help to break up the space.

KITCHEN

Industrial meets vintage meets modern in this bright and airy open-plan kitchen.

The painted floors create a flow from one space to another.The rustic-looking island was inspired by an antique table, while the metal cabinetry took its cue from a Danish kitchen.

DINING AREA

With the original stone fireplace making an impressive central feature and the new glazed study to its rear, this airily spacious zone is the hub of the apartment.

The bamboo lights above the table (itself made from recycled floorboards) are clad in gauzy drapery, highlighting the height and lofty proportions.

TERRACE

Here, plaster was scraped off to reveal the original 19th-century brickand period-style shutters were installed to create an outdoor room perfect for summer entertaining.

MASTER BEDROOM

Sparsely furnished, but not remotely Spartan, this chic, airy space includes a vast dais to raise the bed, industrial-style rafters in the ceiling and an impressive tiled bedhead/divider that conceals the bathroom beyond.

The ceiling in the master bedroom soars up to four metres high. A pair of matching walk-in wardrobes on either side of the bed help to break up the space. Instead of doors, linen curtains were used for a softer feel. The four-poster was inspired by a Balinese design; a tiled room divider conceals the shower and basin behind.

The wooden stool helps add some warmth and texture to the white space.

A bathfits in perfectly within the large arched window.

MASTER ENSUITE

Throughout the apartment, details such as these hanging Australian light fittings are minimal, so that nothing detracts from the feel that you’ve stepped into a peaceful urban oasis.
