David Thompson
Architect Ltd / Services

Architecture is a rapidly changing, knowledge-based, service industry, where firms can specialize in a particular market sector and team with other practices and other specialized consultants to broaden their service base. DTAL is proud of our achievements in smaller public and private projects in Ontario, but also has experience in teaming with larger firms on cultural, secondary educational and post-secondary educational projects. The is committed to maintaining a high-level of design service and promoting client satisfaction.


Traditionally, Architectural services were limited to the design, tender review and construction review of buildings, reflected in the six typical sequential stages of a project:

  • Pre-Design
  • Schematic Design
  • Design Development
  • Contract Documentation
  • Tender Review and
  • Construction Administration

For a small firm, the scope of work provided by DTAL is diversified and can easily be modified to suit a particular client’s needs. Site assessment and Feasibility studies, for example, are often overlooked by many clients, but are a valuable part of our services. These allow a client to explore a means to deliver the project, test the extent of constraints, discover unforeseen possibilities, define the parameters of site, space program, potential building technology, evaluate sustainable opportunities and refine a realistic budget prior to committing to a project.
