PENTHOUSE S | Sitges, 165 sqm

Hand-brushed pine wood and warm white tones give this Penthouse a suspended atmosphere between Nordic and Mediterranean. The kitchen is the open place that unites the two terraces facing the first line of the sea and the mountains, creating a convivial and dynamic spatial continuum.
Sliding panels and integrated doors allow flexible spaces to adapt to the intensity of variable use according to the different occasions, from a weekend as a couple to a meeting of the whole family.

PENTHOUSE L | Barcelona, 54 sqm

The Japanese inspiration, interpreted in the sense of praise of the void that allows the absolute flexibility and adaptability of spaces, is the Concept of this house.
The spatial device that materialises this void is the system of sliding panels, “shoji” made by hand, which fluidly and flexibly articulate the space. The materiality of the place is expressed through natural and raw finishes: the delicacy and apparent fragility of the rice paper framed by light frames of wenge tinted wood, the texture of the brushed oak parquet, the palette of warm and earthy tones of the microcement and the stuccos.

CITIZ HOTEL | Toulouse, France

4 Star Boutique Hotel, 64 rooms, tea room, seminar, meeting rooms.
At heart of this restoration of a listed building in the historical centre of Toulouse, the interior design defines an elegant style inspired by the dominant pink color of the town. The mauve tone is the leitmotiv of the hotel decoration in the rooms and the public areas.
The combination of precious materials such as velvet fabrics and gold lamps with industrial finishing as the glass and the natural iron, establishes a dynamic relationship between the historical atmosphere of the building and the contemporary personality of an urban hotel. On the ground floor a cosy and relaxed Tea Room allows the guest to relax whilst keeping a visual connection with the city life thanks to the full-height glass openings in the façade.
