Cho & Urano is an architecture firm in Salt Lake City, Utah providing a full scope of services on projects of various types and sizes, and engaging in architectural research through experiments and theoretical projects.

We started in 2020 after winning an international competition with our project House for Our Mothers. Prior to that we worked in offices in Los Angeles, Beijing, Seoul, San Francisco, and New York.

We approach each project as a continuing investigation into relationships between architecture, structure, and landscape, using sketches, models, and collected images.

Our research has touched on a variety of subjects, including houses, housing, urban design, and infrastructure. It has been exhibited in Seoul, Los Angeles, and New York, as well as at the International Architecture Biennale in Rotterdam, and has been published internationally in A+U, Shinkenchiku, and others.



Hansong Cho received a Bachelor of Architecture from the University of Seoul and a Master of Architecture from Columbia University’s Graduate School of Architecture, Planning, and Preservation. She has managed numerous residential and cultural projects in New York for the offices of Kyle May, Toshihiro Oki, and Julian von der Schulenburg. Her personal work has been exhibited at the International Architecture Biennale in Rotterdam, the Hunter East Harlem Gallery in New York, and was featured in a retrospective exhibition of Columbia University’s best housing projects produced over a 40-year period. She has served on design juries at RISD, UCLA, USC, and Texas Tech, and is an adjunct instructor at the University of Utah School of Architecture. Hansong is a licensed architect in the State of Utah.


Sasha Urano grew up in Honolulu and Salt Lake City. He holds a BA in Architectural Studies from UCLA, where he graduated with distinction, and a Master of Architecture from Princeton University. He has worked in a number of offices in the U.S. and Asia including Jones Partners Architecture, MAD, Mass Studies, and IDEO. Prior to co-founding Cho & Urano he spent four years as a project architect at Levenbetts in New York where he managed, among other things, a winning competition proposal for a public sculpture in Lower Manhattan and the renovation of a public library in Brooklyn. He has served on design juries at UCLA, USC, and Texas Tech, and is an adjunct instructor at the University of Utah School of Architecture.

Competition, 2024
This is a park for the Banpo neighborhood of Seoul, Korea. It is also a roof, bridge, museum, noise barrier, sculpture garden, bird sanctuary, hiking trail, and viewing platform.


House, 2023
A series of custom wood furnishings for a historic 1,000 sq ft. brick cottage, designed to resolve eccentricities of the 1890’s interior while adding storage, seating, and work surfaces throughout.


Office (in progress)
A video production company headquarters designed to reflect the character of its more manufacturing-oriented neighbors as well as the active railroad line on which it abuts.



Competition, 2023
An everything center built on the former Salt Lake Bees stadium site, dedicated to the mascot of not only the baseball team but of the entire Beehive State, a community of people so industrious as to compare themselves to a colony of insects.


Competition, 2022 (Honorable Mention)
A museum dedicated to the Righteous Army, a civilian militia credited with defending Korea against numerous invasions throughout its history.


Project, 2021
This housing proposal takes its name from the mother-in-law unit, also known as an accessory dwelling unit or ADU.


Competition, 2021 (Runner-up Prize)
Runner-up in the Salt Lake City Tiny Home design competition.



Competition, 2020
A public park formed from the selective modification of an abandoned railroad tunnel and landmark drawbridge on the Seekonk River in Providence, Rhode Island.


Furniture, 2020
A coffee table made from a discarded slab of granite.


Project, 2020
An architectural pavilion for a five-sided traffic island, designed as an in-situ strategy for preserving a cluster of rare trees threatened by industrial pollution.


Furniture, 2020
A study in aggressively low-cost custom furniture-making using materials bought and cut at the local lumberyard (for a dollar a cut) and assembled by the client using a screwdriver.


Project, 2016
This conceptual proposal explores the intersection of architecture, megastructures, and weather through the creation of electrical storms.


Project, 2016
Based on a parody of the “1909 Theorem” cartoon in Delirious New York, this theoretical project for apartment housing uses gardens, galleries, and platforms as a way to fine-tune the boundaries between private and shared domestic space, and seeks to create healthy social interactions between households both vertically and horizontally through the use of three apartment types.


Project, 2015
A radical vision for a heavily polluted five-mile stretch of New York’s East River, dumping ground for 139 combined sewer overflows (C.S.O.’s), wherein the city begins a slow process of expansion into the river through new construction methods applied at the convergence of a number of social and economic forces.


Competition, 2013
In this house two artists are free to shape their own space using partitions that slide and rotate on gridded tracks in the floor and ceiling.


Project, 2012
In this project we explored an alternative formal strategy for a single-family house with an emphasis on the house itself and the objects inside it. Taking the wall as the house’s primary tectonic element, we attached to it all the fixtures and furnishings of a family of four—each implying spatial needs such as floor area, clearances, adjacencies, and privacy—and contoured the wall on radial curves to fit within a legally allowable zoning envelope.


Project, 2012
This study considers a medium-density strategy for an unbuilt flag-shaped lot partially surrounding the client’s cottage, which occupies the smaller lot to the east. The house comprises a single wall that is contoured to fit between the dense formation of trees, capturing a narrow, two-story-high pocket of space and punctuated by enormous windows. It attempts to synthesize the site’s chief characteristics—north-facing slope, dense tree growth, elevated canopy—with an architectural enclosure flexible enough to accommodate two or three households in a variety of configurations.


Project, 2024
An addition to a video editing studio conceived as a camera with two apertures, a larger one in the roof for daylight and a smaller one in the wall—a peephole made from salvaged optics and ground glass—for capturing views of the street.


Competition, 2023
This is the next chapter in the varied history of Jamsu Bridge, a half-century-old bridge on the Han River in Seoul originally designed for military vehicles, but now, and for the foreseeable future, a haven for pedestrian and bicycle traffic linking Seoul's northern and southern halves.


House (in progress)
The needs of a growing family of seven prompted this residential addition, which includes a new kitchen, office, library, outdoor deck, and spa patio, designed as riffs on the original tract house’s vernacular.


Competition, 2022
A master plan for the New Agricultural Resources Management Institute (N.A.R.M.I.) in Gyeongsangbuk-do, South Korea, loosely based on the Roman planning convention of ‘cardo’ and ‘decumanus,’ and integrating indoor storage, seed production, and office spaces with outdoor drying fields and machinery circulation paths.


Project, 2021
To build this ADU (accessory dwelling unit), four triangular structural modules are laid sideways and packed together to serve as the formwork for three concrete walls, then removed through the open fourth side and recombined to become the roof structure.


Competition, 2021
A cultural park consisting of exhibition and educational facilities and a columbarium to commemorate the victims of the Sewol ferry disaster of 16 April 2014.


Project, 2021
This is a speculative proposal for the Great Salt Lake State Park, an existing park with a yacht club and marina that are under threat of obsolescence due to the lake’s ever-changing water levels and annual droughts.


Competition, 2020 (First Prize)
Winning competition entry based on the idea that the challenges of the future might be addressed through big-family living.


Competition, 2020
A ferry terminal on Seoul's Han River shaped to accommodate five 700-ton boats while resolving three misaligned grids from the harbor and park nearby.



Competition, 2020
Restoration and extension of a disused beach lifeguard tower.


Installation, 2016
A design thesis exploring the interplay between heat, air, and architectonic form using non-digital methods, exhibited at Princeton University School of Architecture.


Project, 2016
Conceived amid the fiasco surrounding Zaha Hadid Architects’ competition entry for the New National Stadium, the objective of this theoretical proposal was to explore radically different alternatives to the traditionally un-compact and inflexible Olympic park type. Our approach was to design the park as a dynamic landscape that could accommodate a number of events whose footprints would normally exceed a site of this size, but through careful programming and experimental technology could adapt to different needs at different times.


Project, 2015
Thousands of houses along New Jersey’s coastline are on what used to be zoned as wetlands but have recently been “upgraded” to high-risk flood zones in light of climate model predictions and the damage wreaked by Hurricane Sandy. This study takes much the same approach that local homebuilders have taken, which is to accept the ground as wetlands and to raise the entire house by 11 feet. Where it diverges, however, is in its reconfiguration of basic elements of the suburban American house as a consequence of detachment from the ground.


Project, 2014
Few university campuses deliver the Ivy immersion experience as forcefully as Princeton's, insulated as it is from the outside world since before the nation’s founding. The challenge of proposing any new building here—in this case, one dedicated to the study of art and architecture—lies in balancing expectations of newness on the one hand and deference to tradition on the other.


Project, 2011
This proposal for the Chungmuro bookmaking quarter in Seoul seeks to bring new life to an aging industrial neighborhood following on the global trend of the renewed urban arts district. But it does so with an almost reluctantly light touch, attempting to elude the visitor’s attention and recede into the background through the maximal use of existing elements, a minimal addition of new materials, and the visual concealment of only the most obsolete parts.


Project, 2011
A proposal for a temporary architectural pavilion inspired by a BMW concept car and designed with computer simulations of hair blowing in the wind.
