    RAYHAN BEN LETAIFA – FOUNDER

    Rare Technical Expertise in Interior Design in Montreal

    Before founding Darelle Design, I led project management on large-scale construction sites, including residential towers of over 20 floors. This hands-on experience forged my method: zero tolerance for improvisation.

    I don't just design beautiful spaces. I create technically feasible interiors, mastering construction plans, municipal permits and complex budgets. I am the solid link between your dream and the reality of the construction site.

    OUR VISION

    Expertise in Interior Design & Real Estate Valuation

    At Darelle Design, we go far beyond simple interior decoration. We conceive interior design as a strategic value-enhancement lever. Each project is designed to optimize space, improve functionality and create coherent, sustainable and aesthetic environments, adapted to the realities of the Montreal market.

    Our approach is based on solid experience gained through renovation and interior design projects carried out within established structures, particularly on plexes and residential rental projects. We know how to identify interventions that generate real impact, both on daily use and on the value of a building. From the design phase, we integrate the principles of real estate enhancement to ensure profitable, thoughtful projects adapted to the Montreal context.

    Why choose an interior designer in Montreal for your project?

    Calling on an interior design firm based in Montreal means benefiting from expertise that goes far beyond aesthetics. We design sustainable and functional spaces adapted to the specifics of the Montreal real estate market. Each neighborhood has its particularities, technical constraints, and valuation potential that we master, from Plateau Mont-Royal to Griffintown, including Westmount and Mount Royal.

    Municipal By-laws & Permits

    Renovating in Montreal requires perfect knowledge of municipal by-laws. Whether you are in a downtown condo, a Plateau triplex, or a historic building in Westmount, we know how to prepare compliant plans and obtain necessary approvals.

    Local Suppliers & Montreal Network

    Our network is firmly established in Montreal. We collaborate with trusted local suppliers and artisans for your materials (ceramics, lighting, custom furniture). This reduces delays and guarantees smooth management.

    Profitability & Real Estate Market

    Each Montreal neighborhood has its own dynamic. Investing in a high-end kitchen does not have the same impact in the Plateau as in Griffintown. We help you avoid over-improvement while creating the "wow" effect that maximizes value.

    Varied Architectural Styles

    From the contemporary apartment of a downtown penthouse, to the typical Plateau triplex or renovated duplex, we master the technical challenges specific to the Montreal housing stock.
