noun \ˈkwȯr-əm\

DQI believes in architecture that values simplicity and efficiency. Our thoughtful designs create pleasing spaces within minimal footprints. Smaller can be better… better for the client, better for the community, better for the environment.

DQI believes in architecture that values input from each member that is involved in a project. The ultimate goal is to bring the sum of all the dreams, expertise and skills to the next level…beyond what any one element could have created independently.

DQI believes in architecture that values the building process. By offering design and building services together, we are able to create a seamless flow of ideas and execution.

The Team

Without a doubt it is our experienced, skilled and cohesive team of professionals that has been the key to DQI’s portfolio of successful projects. Our group has been working together for many years and brings an extremely high skill set in each of their areas of expertise. Equally important, the DQI team works hard to create a positive, friendly and accommodating atmosphere throughout the project.

DQI provides design services to develop a unique and creative solution to your project. Within the design process DQI is efficient and experienced in the many steps that may be included in the design. Among others, these steps could include pre-purchase property assessment, zoning checks, zoning by-law amendment applications, site plan approval applications, minor variance applications, consent to sever applications, working drawings, permit acquisition, and dealing with conservation authorities and heritage planning.


In addition to our Design Services, DQI offers our clients the option of also having our team complete the construction phase. DQI extends beyond the design phase to be able to seamlessly take your dream from paper to reality. We have a team of trades and suppliers that work with our experienced DQI Project Manager and Interiors Team to build a high quality, custom home. Organizing and actually building a home can be an arduous task, but our team works with you through the entire project.  The Project Manager will schedule and supervise the site and the trades in order to keep the project safe and moving as efficiently as possible. Our in-house design team for both interior finishes, landscaping and exterior finishes will work with you to ensure the finishes and style of your home match your needs and tastes. Effective communication is one of the most important elements of a construction project. Over the course of the project, the DQI team provides a weekly summary of scheduled tasks in order to keep the client fully aware of project progress. As the construction phase progresses, site visits and consultations with Jonathan ensure that the construction team incorporates any further customization of the plans into a truly spectacular finished project…your new home.
