On Sight Design formed in 2007. We are owned and operated by Wendy Masens. She has been involved with the Interior Design industry since 1992 and has worked for various design firms over the past 20 years. Through her varied experiences she developed a loyal client base and decided that she could better serve them with her own company so On Sight Design was born.

The majority of our experience is within the commercial office sector. We also have clients in the areas of Industrial offices, Medical facilities and Residential.

We have a variety of jobs in our portfolio ranging from under a thousand square feet to over 40,000 sq.ft. We enjoy designing everything from the traditional office to the contemporary all the way to the unique. We have experience working in standard glass and steel office buildings as well as brick and beam loft style spaces.

We are fully BCIN registered for large buildings, small buildings and homes. We are also a member of the Association of Registered Interior Designers of Ontario (ARIDO).

We work directly with clients as well as with General Contractors, Project Managers, Property Managers and Developers. Together we design and co-ordinate new tenant move-ins, building upgrades and general renovations.

We look forward to an opportunity to work with you on your future project and would be pleased to submit a proposal for you to review.
