Studio

Where Disciplined Craft meets Creative Vision.

Metz Design Group is a Toronto-based interior design studio creating refined, modern spaces for commercial and residential clients across the GTA and beyond. We bring together technical rigor and creative intelligence to design environments that feel calm, intentional, and built to last.

The Founder

Metz Design Group was founded in 2013 by Ioanna Metz Ionescu, who brought together a strong technical foundation with a considered approach to interior design. Since then, the studio has built its practice around creating thoughtful, sophisticated environments shaped by the requirements, character, and context of each project.

Ioanna is a Registered Interior Designer with the Association of Registered Interior Designers of Ontario (ARIDO) and an NCIDQ Certified Interior Designer since 2016. Her background in both engineering and interior design informs a practical, analytical approach to space planning and construction, balanced by a strong sensitivity to proportion, material, detail, and atmosphere.

She leads the studio with the belief that successful interiors require both clarity of process and confidence in design judgment, resulting in spaces that are thoughtfully conceived, technically resolved, and distinctly unique.

Our Philosophy

Design with intention. Build with care.

For every project, we adopt a holistic approach, considering the architecture, scale, budget, and the people and business within the space, all while keeping the long-term objectives in mind. Our work is rooted in clarity and elevated through refined materiality, warm tones, thoughtful lighting, and complex detailing.

We don’t decorate. We design with precision, deep construction literacy, and a clear understanding of how a space will look, feel, and function years after the project is complete.

 

What Defines Our Work

Our Process: Not a Signature Style. Just the Right Response.
Every project reveals its own direction. We uncover what it can become, shaping every design as a response to its purpose, context, opportunities, and constraints. From concept through construction, we guide that vision with precision, clarity, and intention.

01 / Context & Opportunity

We do not look at a space with a preconceived aesthetic. Instead, we analyze the architectural bones, the surrounding environment, the natural lighting and your unique project needs to identify the hidden opportunities within your project’s physical and logistical constraints.

02 / Purposeful Response

We translate those insights into a highly intentional design concept. Every finish, layout choice, and lighting plan is engineered specifically to answer the spatial problem we are solving, resulting in an interior tailored to your purpose.

03 / Guided Precision

A great idea only succeeds if it is executed beautifully. From procurement through construction, we act as disciplined stewards of the design—working side-by-side with builders and trades to deliver the finished space with complete technical clarity.

04 / Technical Expertise

As ARIDO-registered and NCIDQ-certified professionals, we seamlessly navigate the complexities of the Ontario Building Code, zoning, and municipal approvals. By identifying regulatory issues early, we eliminate friction, prevent costly delays, and move your project forward with complete compliance.

05 / Intelligent Value Engineering

Value engineering should protect a design, not dilute it. We continuously evaluate materials, systems, and specifications to optimize performance and respect your budget—all while preserving the integrity of the original design intent.

06 / The Full Package

We lead every project from first sketch to final walkthrough. By handling concept, documentation, sourcing, and construction, we provide a single point of view and a single team accountable for the whole result.
