Context & Intent
Located in a dense urban fabric combining artisanal activity, local shops, and residential buildings, the VLR project is part of a broader strategy of local renewal through the construction of a new R+2+attic building housing a mixed program: retail space, a company showroom, office areas, and a family apartment. The operation is set on a plot formerly occupied by a single-family house, now demolished.
The proposed architecture is based on a rigorous alignment with the street, a stepped massing toward the garden, and a restrained design language in harmony with the surrounding scales and materials. Through a rationalized structure, a clear hierarchy of functions, and careful construction quality, the project aims to reconcile controlled density, legible uses, and long-term durability.
Functional Program:
-Basement: Parking (10 spaces), storage rooms, cellars, and technical area
-Ground floor: Dual-aspect retail unit (in shell condition) facing the street, company showroom opening onto the garden
-First floor: Office space — headquarters of TRX Agencement
-Second floor + attic: Duplex family apartment
Each unit operates independently yet remains interconnected, with clear circulation paths and separate access points. The showroom, accessible by appointment only, is internally connected to the company headquarters by a private staircase.
Architectural & Constructive Approach:
The street-facing façade respects the rhythms and proportions of the neighborhood. A tinted precast concrete base defines the commercial ground floor, while the upper levels are clad in light brick, echoing the spirit of surrounding buildings. Powder-coated aluminum elements — cornices, lintels, shutter boxes — ensure detail consistency and alignment with the surrounding context.
The building adopts a load-bearing masonry structure, with timber or mixed wood-concrete floor systems depending on the level. The envelope is designed using dry construction methods, with bio-sourced and recyclable materials (wood, low-carbon concrete, natural insulation).
Energy & Environmental Performance:
The project complies with RE2020 regulations for residential and office areas, and RT2012 standards for commercial spaces.
It integrates a series of simple yet efficient technical systems:
-Enhanced exterior insulation (façades, roofs, and floor slabs)
-Triple-glazed windows and motorized external solar shading
-Air-to-water heat pump for heating and domestic hot water
-Underfloor heating with complementary emitters (radiators, towel dryers)
-Dual-flow mechanical ventilation / cross natural ventilation
-Healthy finishes (lime-based plasters, bio-based paints, recycled acoustic panels)
Together, these choices aim for energy efficiency, long-term durability, and ease of maintenance — without technological excess.
