Joleen Constantis

Principal Designer

Joleen is the Owner of and Principal Designer at Volume’s of Space. With a passion for colour, architecture and design, and 20+ years of experience in the industry, she is committed to helping bring your design vision to life. From consultations and brainstorming, to design, renovations and everything in between, Joleen is here to guide and support you every step of the way.

With career beginnings in the kitchen and bath industry, Joleen has since acquired multiple certificates from the National Kitchen and Bath Association and qualified with the Ministry of Municipal Affairs and Housing to design for the public under the guidance of the Ontario Building Code (BCIN # 27755). She stays up-to-date on evolving design regulations, standards and trends by attending industry trade shows, supplier showrooms and galleries, and relevant seminars.

With an endless energy and enthusiasm for design, Joleen pushed herself to venture into own business roughly 13 years ago, and incorporated Volumes of Space Inc. over five years ago. She firmly believes that every project is worthy of the best design. This approach has resulted in a business that offers a full spectrum of services and flexibility for clients. With strong attention to detail, endless creativity and a highly-skilled team of craftspeople and contractors, Joleen has proudly developed a reputation for going above and beyond the expectations of each and every client.


Kelly Ross

Senior Designer

Kelly approaches every project with creativity and pragmatism. Her effective approach is the result of an education and 15+ experience in both business and design. Kelly has experience in residential interior and architectural design, which originally took place in Toronto, but, in recent years, within her hometown of Guelph. Kelly’s diverse experience includes interior design and project management for whole home renovations, architectural design and building permit services for renovations and additions, detailed kitchen and millwork design, and green building science consulting. Kelly is a qualified designer with the Ministry of Municipal Affairs and Housing (BCIN #38260).

In addition to her work in design, Kelly is also a licensed Realtor® – if it has anything to do with houses, she’s interested! The advantage of this combination of skill sets is two-fold. For her design clients, Kelly can advise on which upgrades will improve resale value. For her real estate clients, Kelly uses her design vision to help them find that diamond in the rough.

While adept in all areas of residential design, Kelly particularly excels at and has an interest in thoughtful and efficient use of space. She believes that bigger does not necessarily mean better, and treats every job, big and small, with the same amount of effort, dedication and enthusiasm. Kelly likes to bring forward innovative ideas, skillfully guiding her clients through the design process to create the best possible living spaces for both their needs and enjoyment.
