Truly personal spaces

Curated interior design services for ‘outside the box’ designs.

Dual Design Co.

Dual Design Co. is a residential design studio located in Vancouver, BC, servicing the lower mainland and various areas near Belleville, Ontario.

Principal designer and owner Kayla Coulas started Dual with two main things in mind: to craft spaces for clients that didn’t look like anyone else’s and to create accessible design services for all budgets through full service design or curated E-design packages.

Born from the principles of duality, Dual Design Co. recognizes that humans are multifaceted beings that move, evolve, and grow. Growing up in Belleville, ON and now living on the westcoast, Kayla experiences the power of duality on a daily basis. Vancouver is home but much of her life story is still firmly planted in eastern Ontario, where her family resides.

This duality influences the entire design process at Dual. We curate designs that reflect your uniqueness and harmonize opposing traits, bringing to life a truly personal space.
