Karen Stonely, AIA LEED AP began independent practice in Maryland and New York in 1991 developing a substantial catalog of residential and commerical projects while concurrently studying at the Urban Glass Workshop in Brooklyn, New York.  Her fabrications are a part of the permanent collection at Rice University, the Garrison Forest School, and are privately collected.  She is LEED accredited and is NCARB certified and currently holds a liscence in New York, Maryland, Connecticut, Florida and New Jersey.  Prior to founding the studio with Peter Pelsinski in 1995, she interned at Robert A M Stern Architects (1990-91) as well as managed and completed the Plaza de Los Ancianos De Wilson, a $7 million HUD-funded elderly housing project in Brooklyn, New York (1991-1996) with late architect Penny Wells Yates.  

Stonely and Pelsinski work collaboratively on all studio projects and Ms. Stonely’s expertise lays in her design and management skills, business accumen, mentoring skills, flexiblity, and her broad ranging curiousity about the both how both the built and phenominal  shape the human experience.

Ms. Stonely has led a parallel career in public service.  She currently serves as the Vice President of Open House New York, is a member of the Charlie Byrd Society at The Mainstay Cultural Foundation, and resides on the Student Leadership Team and the Chair of the Inclusion Committee at The Spruce Street School. She founded LAAB (Life as a Brain) in 2012 to sustain rare neurological research and support.  She was on the initial Advisory Committee of the NYC’s Downtown Alliances “Volume-Voices of Lower Manhattan”, Vice President The Bindery Condominium Association for 11 years, participated in the Mentor Program at the NJ School of Architecture, on the Development Committee for the Architectural League of New York, and was a founding chair of the “Friends Committee” for the Design Trust for Public Space.  SPAN completed the office for the NY Council for the Humanities pro bono, participated in the Kips Bay Boys and Girl’s Club Design Showroom, and she leads the studio’s annual philantrhopic endeavors. She speaks regularly at architectural events such as Dwell on Design, the Architectural Digest Home Show, and as a juror for annual awards for the Architectural League of New York, the Architect’s Newspaper and CC&G to name a few. 

Ms. Stonely graduated with a Bachelor of Art followed by a Bachelor of Architecture from Rice University, was awarded the Edward B. Arrants Medal and inducted into the Tau Sigma Delta Society.




Principal Peter Pelsinski, AIA LEED AP, is one of the youngest recipients of the prestigious Architectural League of New York’s Young Architects Forum.

He is a founding member of the award-winning collaborative Operatives (1991-1996, now LTL), leading multiple urban competitions and designing and fabricating exhibitions. These included “The Pull of Beauty” exhibition with curator Kiki Smith, and “Slip Space” curated by Mark Wigley, both at the Storefront for Art and Architecture.  Each was awarded ID Magazine’s “Best of Category – Environments,” in 1996 and 1994 respectively.  He is the designer of “Metroscopes,” the award-winning public art installation in the UMSL South station in the St Louis light rail system. Prior to practicing with Karen Stonely, he interned at Diller Scofidio Architects and Michael Graves, and was the lead designer of the residential and development practice for developer Peter Moore.  He is LEED acredited and NCARB certified and currently holds a liscence in New York.

In addition to the studio’s prolifically built work, SPAN continues to work on speculative development projects, pursue competitions, and Mr. Pelsinski is deeply invested in the advance of architectural education.  He currently is a professor at Princeton Univeristy and runs the integrated building design seminar and laboratory.  Pelsinski coordinated a reconstruction-focused traveling studio between the New Jersey Institute of Technology School of Architecture and the schools of architecture at Poznan and Warsaw Universities, comparing the building site of the WTC with post-war sites in Berlin, Warsaw and Poznan.  Pelsinski is a member of the Charlie Byrd Society at The Mainstay Cultural Foundation, formulated budgets and curriculum as one of four members of the inaugural Student Leadership Team at the Spruce Street School (PS/IS 397) from 2009-12, and was a founding chair of the Friends Committee for the Design Trust for Public Space.  He is an invited guest on many architectural juries and reviews, including the AIA DC Unbuilt Awards, and the Brooklyn Builds Design Awards and frequently lectures about SPAN’s work publically.  SPAN was selected as one of five national firms to participate in the “Friends of Hudson Square Design Charette Workshop & Exhibition” lead by Mr. Pelsinski. 

Pelsinski and Stonely work collaboratively on all studio projects and Mr. Pelsinski’s expertise lays in his design, collaboration and fabrication skills, wide ranging intellectual expertise, boundless determination, and his pursuit to explore, experience and create within our built and natural world.

Pelsinski graduated with a Bachelor of Science from the University of Maryland and a Master of Architecture from Princeton University, where he received the Susannah Underwood Scholarship, the Pella Thesis Prize for outstanding design, and was a finalist for the SOM Traveling Fellowship.  He is a recipient of the American Institute of Architects Henry Adams Medal.
