A Curated Record of Craft & Constraint.
Each project below is a complete case study. We present the problem, the material decision-making, and the documented outcome—not just the final photograph. This is how we work.
The Parisian Facade Reimagined
The client brief was a paradox: preserve the soul of a 19th-century Haussmannian facade while engineering a fully modern, open-plan living space within. The original structure suffered from severe structural decay and obsolete utilities. The challenge wasn't aesthetic; it was gravitational.
Our solution was surgical. We installed a discreet steel reinforcement system within the original shell, avoiding any visible change to the facade. For utilities, we routed a new, high-efficiency HVAC system through the original cornices—a meticulous process requiring 3D modeling to locate centuries-old plasterwork without damage.
The outcome is a study in seamless integration. Original parquet floors, painstakingly restored, now incorporate underfloor heating. A central glass atrium—engineered to meet strict daylight codes—floods the open-plan core with natural light. The custom kitchen cabinetry was crafted from reclaimed oak harvested from the building’s own original beams, a detail noted in the project’s architectural review for its material honesty.
Façade restoration, 7th Arrondissement. Original limestone cleaned, repointed, and treated for durability.
Technical Constraint
Historic Preservation Mandate: No alterations to the primary facade shell permitted. Internal steel reinforcement was the only structural solution, requiring coordination with the city’s heritage department.

The Montmartre Atelier: Constraints as Catalysts
A 60-square-meter former artist’s studio. No elevator. A spiral staircase. A strict budget. The client needed a home office, guest suite, and a private terrace. The constraints were not obstacles; they were the design brief.
We simulated the entire construction cycle in 3D, mapping the exact delivery path for materials. The historic spiral staircase could only fit components under 1.2 meters in length. This forced a modular approach: pre-fabricated wall panels and custom furniture built off-site, assembled on-location. To preserve the skylight—a primary light source—we sacrificed a wall of built-in storage, opting instead for a vertical library system that reached the ceiling.
Micro-Scenario
Delivery Day Simulation: Every material piece was CAD-modeled to navigate the 2.1m high, 0.9m wide staircase turns without a single scratch.
Material Glossary
Venetian Plaster: Chosen for its seamless, tactile surface. Applied by hand to avoid the need for paint or drywall seams, saving space and time.
A Portfolio of Material Mastery
Our sourcing ethos: provenance, durability, and tactile truth.
French Limestone
Bourgogne Region
Quarried for countertops and vanities. We manage the entire chain from extraction to the final silicone seal, ensuring consistent porosity and grain.
Reclaimed Belgian Oak
19th Century Demolition
Sourced from decommissioned barns. Our carpentry team stabilizes, planes, and refinishes for flooring and custom millwork, preserving its structural history.
Venetian Plaster
Specialist Application
Applied by hand by our artisans. Creates seamless, breathable surfaces that add depth without requiring drywall seams or paint, ideal for curved walls.
How to Evaluate Our Portfolio
A Real Scenario
“As a homeowner in a historic district, my fear was a generic, soulless renovation. Ironexa didn’t just give us a modern space; they helped us find the story within our own walls, and delivered a final product that feels both honest and entirely new.”
— A Client in the 6th Arrondissement (High-Network Homeowner)
This vignette isn’t unique. It reflects a common challenge: the emotional weight of working within a historic context. Our portfolio is designed to show not just *what* we built, but *how* we think through that specific tension.
What Changes Our Mind
A Detailed, Itemized Quote
We avoid ballpark figures. Transparency in cost breakdown is non-negotiable.
A Site Visit with a Past Client
A glossy brochure is less valuable than seeing craftsmanship firsthand.
A Specific Material Sample
Digital renderings are supplemental; tactile proof grounds the decision.
Scenario: Sourcing a specific French limestone with 4-week lead time to match existing floors. This is a constraint we manage, not a surprise.
