gh3* is a Canadianarchitecture, urbanism, and landscape design practice based in Toronto, led by founding principalPat Hanson and Raymond Chow.[1]
Employing both architects and landscape designers,[2] gh3* has worked on a variety of projects including private residences, pavilions, public parks, commercial buildings, and civic infrastructure, and describes itself as merging modernist values with sustainable design strategies.[3]
Replacing the existing public pool atBorden Park inEdmonton, AB, Borden Park Natural Swimming Pool is the first publicchemical-free outdoor pool in Canada. The project included the creation of a central pool as well as a single-story building housing changing rooms and bathrooms, and a landscaped area with sandy beaches.[4] The building's exterior is made up ofgabion basket walls filled with dark Alberta limestone and has a flat roof.[5][6] The Borden Park Natural Swimming Pool was awarded the 2014 Canadian Architect Award of Excellence and 2019 RAIC Award of Excellence for Innovation in Architecture.[7][8]

Selected by the City ofEdmonton after a 2011 design competition,[9] gh3*'s concept for the Borden Park Pavilion incorporated the site's history as an amusement park and curving pathways.[10] They built a single-story cylindrical structure to house the park's amenities and walkway surrounding it.[11] The exterior is covered in triangular sheets of reflective curtainwall glazing while the interior has a similar triangular motif.[10] The project was awarded the Governor General's Medal in Architecture in 2018.[11]
In 2010, gh3* completed Boathouse Studio.[12] Located onStoney Lake, in Southern Ontario, the photography studio is a glass cube on the edge of the water. The building uses adeep water exchange system for low energy heating and cooling year round.[13] Boathouse Studio received the Governor General's Medal in Architecture (2010).[14]
The Stormwater Facility, on Toronto'sLakeshore Boulevard in theWest Don Lands area, was commissioned byWaterfront Toronto andToronto Water.[15] Completed in 2020,[16] the facility includes a stormwater reservoir, a treatment plant, and a landscape of channels and gutters linking the two.[17] It was constructed from exposed, cast-in-place concrete.[17]
Kathleen Andrews Transit Garage is a bus maintenance and storage facility for Edmonton Transit Services.[18] It is 540,000 sf[19] with five skylit stairways that are topped by topographic installations by German artist, Thorsten Goldberg.[20] The building's corrugated stainless steel exterior is made of freezer panels, normally used for cold storage facilities.[18]
Windermere Fire Station in Edmonton's most notable feature is a pitched roof, with a subtle curve.[21] As part of the City ofEdmonton's sustainability commitments,[22] the station is powered by a rooftop solar array and geothermal heating and cooling, making it the first net-zero emissions building in Edmonton.[23]
