Dear Admissions Committee,

I am writing this letter to highly recommend Sun Yao as a candidate for the Master’s program in architecture in Canada. I, Zhang Runzhou, am the CEO of HZS Architecture Design Ltd., and I have had the privilege of working closely with Sun Yao since she joined our company in the summer of 2012.

During her time with us, Sun Yao has exhibited great enthusiasm for work and a strong ability to learn, leaving a lasting impression on me through her work on numerous projects. One standout project was the bid for the Yinchuan Wanda Hotel in 2013, where she actively participated in brainstorming sessions and provided key ideas for the team. Her design proposal was ultimately approved by the client and we won the bid. During the design development and construction coordination phase, Sun Yao was responsible for the detailed design of the building. She paid great attention to details and strived for accuracy and innovation. In order to control the cost of the facade construction, she constantly communicated with the curtain wall company and material suppliers. Through material selection and repeated optimization of different structural nodes, she assisted the client in achieving a 20% cost reduction compared to the winning proposal. This project also received recognition as an outstanding project of Wanda Group in 2016.

Sun Yao has always been proactive and eager to learn new skills, which has greatly improved the efficiency and quality of our design team’s work. One particular instance that impressed me was during the design of the Guangzhou Nansha Wanda Commercial Complex project in 2015. When the design team encountered challenges in efficiently addressing the architectural complex surface design, Sun Yao took the initiative to self-study Rhino design software and mastered the skills within 20 days. This brought great convenience to the team and ensured the timely and high-quality completion of the project. Her outstanding work was highly appreciated by the design team. What pleased me the most was that her proactive attitude also influenced other colleagues in the company, creating a better work atmosphere and self-improvement environment.

Aside from her work performance, Sun Yao’s personality and approach have made her popular among her peers. She is a very confident person who never hesitates to express her opinions during the work process. Whether facing colleagues or clients, she can articulate her ideas well and receive positive feedback. At the same time, Sun Yao is also a humble person who listens attentively to the instructions from leaders and suggestions from colleagues, constantly optimizing her work in a team collaboration setting.

Sun Yao has always been committed to her professional development. During her spare time, she continues to consolidate her professional skills through learning and practice, and continuously develops new knowledge and skills in the field of architecture based on practical needs. In our conversations, I learned that she obtained the LEED AP certificate in 2016 and the national first-level registered architect professional qualification in 2020. I believe she has enough experience and competence to realize her ambitious goals for her professional development. Therefore, when she told me about her plan to pursue further studies abroad, I fully support her. I am delighted to write this recommendation letter for Sun Yao and sincerely hope that she will be admitted to your esteemed university.
