Decor & Design Week #303: From Warsaw to Cap Ferret, ten interior design finds

For issue #303, Planète Déco explores ten new interiors featuring designer decor or contemporary one. But it also showcases inspiring and dream-inducing outdoor spaces. This week’s roundup takes us on a journey from city apartments to seaside homes.

In Paris, a Haussmann-style apartment is transformed into a family duplex on Rue de Rivoli. A 40sqm apartment overlooks the Ligurian Sea. In Barcelona, an endless hallway disappears to make way for light. An apartment blends soft tones with the vibrant colors of Brazil in Poland. In Copenhagen, a former carpentry workshop is transformed into a 234sqm home.

We discover in Bordeaux, an 18th-century mansion that hides a complete transformation. In Barcelona, another early 20th-century villa regains its full splendor. In a Catalan village, two old houses merge into one. A 42sqm summer retreat appears twice as large as it actually is. In Cap Ferret, a wooden house boasts the most beautiful view of the Arcachon Basin. Ten locations, ten stories, one shared desire to live well at home.

In Barcelona, an endless hallway disappears to make way for light

In the Sarrià neighborhood, this 180sqm apartment hid its spaciousness behind dark wood paneling. An endless hallway and massive doors had closed off the space for far too long. Interior architect Sandra Mora opened up the space and let in abundant light. The owners love the new kitchen so much that they never want to leave it. Source: El Mueble

In Warsaw, an apartment blends Polish charm with the colors of Brazil

The Furora studio designed this apartment for a family split between two countries. Diana Żurek and Gutek Girek opened up the closed-off rooms and created a fluid flow between spaces. White dominates the walls and serves as a backdrop for strategic pops of color. A colorful chandelier by Hakola and pink and orange stripes add vibrancy to the kitchen. Source : Livingetc

In Copenhagen, a former carpentry workshop becomes a 234sqm home

They removed part of the upper floor to reveal the original timber frame and its 7.5-meter-high ceiling. The exposed brick walls and terrazzo floors give it a warm, artisanal atmosphere.
