LSS Architecture is an award winning architectural studio inspired by innovation in design, the craft of construction, and a collaborative approach that places our clients’ needs at the center of the design process.

LSS Architecture

LSS is a dynamic and collaborative architecture studio: we value experiences over objects, open dialogue over ego, authenticity over artifice.


We define architecture as a process of restless discovery and collaboration. We define success as a carefully designed space that can be truly felt, lived, and experienced.


We are a communal practice—from the artists and makers who surround us every day as colleagues and collaborators, to the clients and communities that we design our work with and for.

LSS Community

In 2001, Leroy Street Studio founded Hester Street Collaborative, a nonprofit participatory design/build workshop, to improve the physical environment in underserved NYC neighborhoods. HSC’s guiding principle is that civic engagement in participatory design helps disadvantaged residents create a profound impact on their communities. HSC works with local residents to transform neglected public spaces in parks, schools, and affordable housing developments through a design/build process which allows community stakeholders to play a hands-on role. This approach encourages a sense of ownership in the built environment by offering members of the community the opportunity to plan and realize a shared vision. In addition to running an extensive design/build education program in several New York City public schools, HSC uses its architecture, design, and community-visioning expertise to initiate site-specific projects that work in tandem with community-led efforts to improve parks and other neighborhood spaces.

LSS Construction

LSS founded our construction management company to intensify our pursuit of design rooted in craft, adopting a wholistic approach to design and construction that offers hands-on project delivery and results.


Through this multidisciplinary, collaborative approach, we bring a high level of quality and value to every project—optimizing design, cost and schedule, and providing a single point of communication and responsibility.


This attitude is central to our firm's culture, and reflects our core values: that a deeper understanding of construction informs our architecture, and our experience as architects makes us better builders.
