MHouse: Toronto Interior Design Studio

Toronto interior designer Shirley Meisels has spent over two decades refining what great design looks—and feels—like. Known for her editorial eye, fearless material pairings, and the ability to bring clarity to even the most complex residential projects, Shirley is equal parts creative, practical, and instinctive.

Her interiors are livable but layered, refined but relaxed—always grounded in the real lives of the people who inhabit them. Her hands-on approach, sharp instincts, and creative problem-solving have made her a trusted name in Canadian design.



Shirley’s work has been featured in top design publications including House & HomeToronto Life, Style at HomeThe Globe and Mail, and Rue Magazine but it’s her reputation among homeowners, architects, and fellow designers that truly sets her apart. She doesn’t just design homes—she designs experiences.

In addition to leading MHouse Inc., Shirley is also the founder of WHouse, a mentorship platform for emerging designers. Through this sister brand, she shares her process, lessons, and industry wisdom with the next generation of creatives.

Full-Home Renovations & Remodels

WHouse:  A New Kind of Mentorship for Interior Designers

WHouse is Shirley’s companion platform for emerging designers and design-adjacent professionals looking to sharpen their instincts and avoid costly project mistakes. Built from decades of experience running MHouse Inc., WHouse delivers the kind of real-world education that most programs leave out.



Through the Design Wisdom course, downloadable DesignBytes, and 1:1 consults, WHouse offers clear, candid insight into the design process—from reading floor plans to understanding lighting, cabinetry, and managing client expectations. It’s not theory—it’s what Shirley and her studio actually use.

Whether you’re a junior designer, a new hire at a growing firm, or a contractor looking to better understand your design counterparts, WHouse was built to bridge the gap between design education and project execution.
