Metz Design Group is a Toronto-based studio creating sophisticated commercial and residential interiors across the GTA and beyond. Founded by ARIDO-registered designer Ioanna Metz Ionescu, our work is rooted in a refined design sensibility, supported by the rigour and clarity of process that bring every detail into focus.
We lead every project from first sketch to final walkthrough, handling concept, documentation, sourcing, and construction oversight under one roof. Clients work with one studio, one point of view, and one team accountable for the whole result.
As ARIDO-registered and NCIDQ-certified professionals, we bring fluency in Ontario Building Code, zoning, and Committee of Adjustment processes. This expertise removes friction, anticipates issues, and gives clients confidence at every regulatory turn.
Our aesthetic is warm, layered, and quietly confident. Clean lines meet considered materials, architectural detail, and thoughtful lighting to create spaces that feel calm, intentional, and timeless rather than trend-bound.
We specify with intent. Every finish, fixture, and furnishing is selected for performance, longevity, and craft, drawing on long-standing trade relationships to bring the right pieces into every project.
We find the alternatives others miss. When a specified material is out of reach, we know which substitutions hold the design intent and which ones compromise it, aligning ambition with budget without diluting the result.
We work the way we communicate: clearly, directly, and with full accountability. Clients are kept informed, advocated for, and treated as partners in the process, never managed around it.
As creators of the built environment, we recognize the profound influence we have and our responsibility to spearhead environmental and societal change. We are committed to a sustainable and equitable world.
