The professional offices of Me Douglas Yip are located in a business centre at the eastern end of the downtown area of Vieux-Longueuil. The historical building was originally constructed in 1864, and has been entirely renovated, with the construction of additional offices in 1989. There are two conference rooms available for meetings.

Rue Saint-Charles is a bustling area, home to many businesses, including all of the major banking institutions, and numerous excellent and reasonably-priced restaurants. The good weather ensures the occupation of the outdoor terraces throughout the summer. All of these amenities are within walking distance of the professional offices.

There is ample street parking on either side of Chemin de Chambly near the offices of Me Douglas Yip, except during rush hours when parking is prohibited on one side.
