Landmark Architecture Ltd. is dedicated to transforming people’s lives and communities through architectural design and programming of municipal, institutional, commercial, industrial and residential projects. Since 1997, our team of architects at Landmark Architecture has been helping clients achieve success, from large multi-million dollar projects throughout British Columbia to small space planning or renovation projects around Vancouver and the Lower Mainland.

With an approach based on collaboration and respect, Landmark has developed a reputation for building stakeholder buy-in and making the architectural process easy and pleasurable. We believe that great design can be accessible to every community. And with a talent for pre-design and technical specification, we know how to maximize value and deliver successful projects that are on time and on budget.
