Welcome to Design Exterieur
Design Exterieur Inc. is a family owned and operated landscaping business servicing Montreal and the Laurentiens since 1987. Initially based out of the Montreal area, Isa Lane started off by designing and constructing small scale gardens in Westmount and the surrounding burroughs.

Through word of mouth, the company quickly began to be involved in some of the largest privately owned gardens in Montreal and with the addition of John Lane, the business expanded to the development of our client’s large country estates in the Laurentiens north of Montreal.  At this point the company was ready to expand and in 2001 Design Exterieur Inc. opened a second office in Mont Tremblant.

Specializing in natural stonework and water gardens, we are proud to offer a unique service to our clients in creating some of the most awe striking gardens in Quebec. Our quality of service is exemplified by the fact that we have been working with some of our clients for more than 10 years.
