Philosophy

In Gaelic, Síol means seed. It is our belief that the seeds for authenticity, potentiality, and balance are sown via design. Design is multi-disciplinary by nature and our practice endeavors to fuse the language of architecture, interiors, and landscapes into a single voice that is manifested in each project. As professionals we guide you in a process of inquiry into self and place. We assist in defining the project while balancing the constraints of budget, time, and quality in what is both a rational and intuitive process.

We want to grow with you. We are under no illusion, the spaces we create are for others. Your complexities inspire us. We create a safe container for expression that is essential to our design process. We see design as a tool for cultivating awareness and unlocking potential.

Self
There is more than meets the eye. Our current paradigm is a victim of the visual. No longer shall we place a hierarchy of the senses. Space, with its materials and shapes, light and shadow, solid and void, is perceived with our whole bodies. These aspects unfold and create relationships that connect us to our environments in a multitude of layers.

Spatial
Site

Where you are matters. Whether urban, suburban, or rural, the site is the foundation of our design process. We are trained to listen and gather information from the multitude of sources that define a site. It is our role as designers to interpret this body of knowledge and uncover the genius loci of the site.
Nature

Nature is our teacher. We have reverence for nature as a process that guides our explorations into sustainable development. From building footprints to outline specifications, every decision is navigated within this lens. We align our practice toward restoring balance in the human ecosystem.

People

ROBO GERSON

Robo Gerson’s design philosophy draws on his experience in photography, work on vintage cars and motorcycles, carpentry, and horticulture. A LEED-certified, registered architect in the State of California and a member of AIA, his wide range of work has included parks, bridges and municipal projects to single and multi-family homes (including his own in San Francisco’s Ingleside neighborhood).

Over the last several years, Robo has had the good fortune of learning from a diverse group of talented architects, as an intern designer for the astute and technical Wayne Barcelon of Barcelon + Jang and a project manager for the visionary Paul Endres of Endres Ware. He eventually transitioned into Senior Architect for Pentagram.

Joining Síol as partner in 2012, he brings to the practice a belief in simple and honest materials and an extensive understanding of how to bring a project seamlessly from conception to completion. Robo, with his extensive experience, continues to guide the team through increasingly complex, creative, and challenging projects.  

KEVIN HACKETT

Kevin Hackett was born in Limerick, Ireland. His childhood was spent immersed in the rugged landscape of the Irish West Coast.The environment anchored his respect for nature and nurtured a passion with the ocean. In his youth, Kevin travelled across the urban landscapes of Europe and was exposed to a richness of architecture and culture. It was his artwork that wove these experiences into the desire to become an architect.

After completing both undergraduate and graduate studies in Architecture at the University of Plymouth in the U.K., Kevin worked at award-winning firms in Ireland, Paris, and Shanghai before moving to San Francisco, where he was appointed Design Director for British architect Johnny Grey’s U.S. office.

In 2007, he co-founded Síol with Jessica Weigley with the intention of promoting a multidisciplinary mindset. Together, they have established a new typology of practice, one focused on an integrative design process that explores a deeper connectivity between self and place.

Kevin has been lecturing on Architecture and Design in the Bay Area since 2006. He previously taught studio at California College of the Arts and currently teaches a class on Design Philosophy at Academy of Art University.

JESSICA WEIGLEY

Design literally runs in Jessica Weigley’s blood as both sides of her family have designed and built homes. So, it was only natural that, she undertook a design project of her own in the eight grade: a remodeling of her bedroom, for which she created not only drawn plans, but also a budget.

Jessica began her career not in design, but in education, earning a master’s degree in the field and subsequently spending time teaching both in Namibia with the Peace Corps and in Hawaii. Upon moving to San Francisco, she transitioned her personal interest in design to the professional realm, beginning with her appointment to Johnny Grey’s U.S. design team.

In 2007, Jessica co-founded Síol with Kevin Hackett. Since that time, she has co-designed several rooms for the San Francisco Decorator Showcase House and was named a “designer to watch” by California Home and Design. Her work has been featured in the San Francisco Chronicle, Houzz, and Remodelista, among others.

Jessica leads the interiors team at Síol and believes that designed spaces are akin to a second skin: something we inhabit, reflecting who we are internally to the external world. Her work with clients on both residential and public projects is characterized by deeply examining the relationship between a space and its future inhabitants.
