What We Think

Certain experiences we’ve had working with communities have shaped how we think about our work, what is our role as a designer and advocate. What can we bring to a situation by virtue of coming from the outside, as we often do? What can we learn from a site? What can people there teach us?


It’s important to join communities we work with so we can gain their trust, get to learn their priorities, values, deep passions, and hot buttons. It’s the same with their sites. One of the great values of being new to the problem and the site is the fresh eyes that we can bring to what is really powerful, beautiful, and provocative. These features or qualities may be so familiar that they have been hiding in plain sight.


We hate importations. We’re always looking for those things that the city is already made of, that make cities unique, turning the familiar into the strange and beautiful experiences that resonate with native culture and create vivid memories that could never exist anywhere else.


Healthy design processes are shaped by deep engagement with the client and community, learning their stories and experiences, not just what they wrote on a note card. In the end, the project is about a communal vision that is forged by the values of the public it will serve. Our job then becomes translating that vision into a physical, material sensibility that resonates with people, that feels both familiar and new at the same time. It’s about the hard work of making things fit and cohere, making them practical, logical, affordable, and something you never forget!

Pablo Alfaro


Pablo’s life has been always shaped by landscape. He was born during one of the biggest floods in Santiago de Chile in 1982, grew up next to the Andes, surfed in the cold waters of the Humboldt current, and studied architecture surrounded by nature in a colonial “casa Patio.” There he did his thesis about fog collection as a sustainable landscape infrastructure to provide water in the Atacama Desert. After obtaining his architecture degree in 2008 he worked in several important landscape infrastructure and public architecture projects in Chile, most of them funded by the Chilean government. His search for arid landscapes of fog brought him to California where he earned an MLA degree from UC Berkeley.


Pablo doesn’t believe in a division between architecture and landscape, hence his work consistently creates linkages between the two disciplines. He’s been awarded the Stephen Lenci Award for Architecture and Landscape Architecture Research, the Randy Hester Award for Ecological Democracy 2015, the ASLA Certificate of Honor, and the ASLA Honor Award 2016 for his project FOGFEST, featured on the cover of LAM Magazine.

Yuqing Nie

Project Designer

You know that “a-ha” moment that parents experience when they see their kid fall in love with something? Not barbies, not cartoons, not playgrounds. Instead, her parents experienced that moment when she first touched a Lego. And thus began Yuqing’s lifelong love affair with Lego and – you guessed it – Architecture. At this point, you may be wondering if the previous sentence is missing the word “Landscape”. You’re right, but please read on; you’ll find out. Here’s her story.


She first began studying architecture as an undergraduate at China’s Central Academy of Fine Arts. It was there where she built a strong foundation, learning about – no pun intended – foundations of structures, technical skills, and developing a profound understanding of arts and design. She practiced her skills over a four month internship at the Beijing office of RSAA, a German architecture firm.


As she began understanding different architectural styles, she yearned for more exposure. That instigated her next move to UC Berkeley’s College of Environmental Design, where she obtained a Master of Architecture Degree. It was there where she took on projects of increasing complexity, blending her creative imagination with meticulous planning, while not forgetting practicality. It was also there where she realized that Architecture and Landscape isn’t as distinct as people make it out to be, and that each complements the other. She wanted to be able to show that in her work, and this goal led her to Harvard’s GSD, where she embarked on a path to obtain a Master of Landscape Architecture degree.


This new foray excited her, and she worked hard to earn an opportunity to intern with Meyer + Silberberg Land Architects – helping to realize their projects by performing concept design, creating construction drawings, as well as rendering and diagram representation.


And if Harvard and M+S LA were initial steps towards her goal, she’s truly fulfilling her goal right now at TLS. She is now diligently utilizing her experience in both disciplines, her technical expertise, and her interest in ecological solutions to design and portray Landscape Architecture projects of TLS. She hopes that these projects will improve people’s quality of life and as a bonus, add a new series to her lifelong love affair’s portfolio.


Xiaoye Xing

Project Designer

Xiaoye joined TLS in 2017. She never hesitates to become a landscape architect with her love of natural landscape. She has deep interests and experiences in hydrological issues, oceans, rivers, creeks, which makes her a good fit for ecological projects. She believes a good design comes from critical analysis and consistent observation.


She will continue to explore landscape design as a living, shifting process but not a static artifact and utilize big thinking with elegant craftmanship

Prior to joining TLS, Xiaoye worked at the OLIN Studio in Philadelphia and SWA Group in Laguna Beach for both deep local and international projects. She holds a Master of Landscape Architecture from University of Pennsylvania, a Bachelor of Agronomy at Landscape Gardening as well as a minor in industrial design from Zhejiang University, China.

Jiawen Chen

Project Designer

Born and raised in a scenic city of China, Hangzhou, Jiawen spent numerous weekend excursions into the mountainous lake circles. She thus grew up with a mystical connection to the sights, sounds, and smells of nature. She studied environmental design at Tongji University to explore the power of nature, followed by obtaining her MLA degree from the Harvard GSD.


Jiawen has a broad interest on topics from geopolitical territory to ecologies. Her work Korea Remade has been awarded the 2018 ASLA Student Award of Excellence. She was also awarded an ASLA Honor Award at the same year for her work Bloom! A Dynamic Landscape Biological System.


Jiawen loves Pikachu, Beethoven’s Piano Sonata No. 8 in C minor, and Unaju(grilled eel over rice).
