“Villa Malevart”: old car parks transformed into an office building

Located in the 11th arrondissement of Paris and nestled at the bottom of a cul-de-sac, the creativity of the H2O architectural agency focused on improving light intake and optimizing existing surfaces in order to maximize spaces. of work. As Natalia ORBAI points out, “The H2O architects agency develops its field of expression on projects varied in terms of size and destination. Our know-how is also expressed through the Eugène heritage architects entity created in 2016 dedicated to resolving the challenges of restoring Historic Monuments.

Modernize the building while retaining the original spirit of the architectural elements

Anxious to bring the building into line with current requirements in terms of performance and living comfort for the occupants, “Villa Malevart” has been fitted with a new exterior curtain wall envelope with integrated openings allowing light to generously penetrate into the interior. interior of work spaces. “The concrete frame, almost completely preserved, accommodates two side patios, as well as a large raised glass volume, symbol of this openness. The existing half-levels are used to create continuous work surfaces and a central staircase serves and structures the space. The roof terrace benefits from a greening program, in order to make it a work space, but also a living space with vegetable garden areas which benefit the rooftop restaurant” specifies the H2O architecture agency.

Curtain wall facades with a design similar to period steel joinery

The exterior envelope of the “Villa Malevart” project highlights large glass surfaces treated with the CONCEPTWALL50-SL* curtain wall and the integration of windows from the Slim Line 38 series, a line of systems combining finesse, elegance and tradition. The aesthetic characteristics of these two technical solutions made it possible to combine the need for energy performance and the desire to maintain the design reminiscent of traditional steel joinery. The ConceptWall 50-SL* curtain wall offers great design freedom while maintaining maximum transparency thanks to extremely thin visible masses (15/50 mm interior and 50 mm for the exterior covers). Designed for building renovation, the design of the aluminum profiles of the SlimLine 38 window allows you to rediscover the charm of steel joinery. As Frédéric DEPRIEZ of the Leuillet company points out, “This rehabilitation project is characterized by the integration of curtain walls with clamping hoods from the ConceptWall50 SL* series, with alternating glass and sheet metal parts, and SlimLine 38 opening frames. The combination of these two products offers the advantage of a coherent aesthetic recalling the charm of old steel structures while being in an optimal economic framework.
