# U.GA Architects Unveils Permeable Mixed-Use Building in Busan Innovative design filters urban noise while embracing cityscape at sharp-cornered site. - **Source:** [ArchDaily Global](https://brifing.si/source/b856ce4a-b51b-4705-954b-40620e034caa) - **Published:** 2026-09-13 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/5e6a12d8-d819-445b-ae7d-fe033109d5f8 ## Project Overview U.GA Architects has designed a 398 m² mixed-use building in Busan's Mangmi-dong district, set for completion in 2025. The structure occupies a challenging acute-angled corner site where a major arterial road meets a historic residential alley. This prime location offers high commercial visibility while requiring innovative solutions to shield residents from urban noise and visual intrusion. The design team led by Dae-woo Yu rejected conventional fortress-like approaches in favor of a permeable filter concept. ## Site Challenges The project site presents unique urban conditions with its position between Busan's dynamic high-traffic road to Haeundae and quaint antique shop-lined alleys. This juxtaposition creates both commercial opportunities and residential challenges. The architects had to address the constant noise from the arterial road while maintaining visual connections to the charming historic neighborhood. The sharp corner geometry further complicated the design process, requiring creative spatial solutions to maximize functionality. ## Design Solution U.GA Architects developed a 'permeable filter' concept that selectively engages with the urban environment. The design allows natural light and city views while providing acoustic and visual buffers for residents. This approach contrasts with traditional closed-off mixed-use buildings by creating graduated transitions between public and private spaces. The architects used the site's angular geometry to their advantage, creating dynamic facades that respond differently to each street condition. ## Material Innovation The project incorporates products from Durastack and Nanumtech to achieve its permeable quality. Material selection focused on balancing durability with aesthetic flexibility to meet both commercial and residential needs. The architects employed innovative construction techniques to realize the complex angular design while maintaining structural integrity. These material choices contribute to the building's ability to filter urban stimuli without complete isolation. ## Team Composition The design team included Soon-jung Shim and Hyo-kyung Kwon under the leadership of Dae-woo Yu. Wooeun Construction Co., Ltd. served as general contractor, bringing the ambitious design to life. This collaboration between innovative architects and experienced builders was crucial for executing the project's unconventional concept. The team's combined expertise allowed them to navigate the site's technical challenges while maintaining design integrity. ## Commercial Potential The building's prominent corner location offers exceptional visibility for retail and commercial spaces. The permeable design creates engaging street-level experiences that attract foot traffic while upper floors maintain residential privacy. This balance makes the project commercially viable while serving community needs. The 2025 completion date positions it to benefit from Busan's ongoing urban development. ## Urban Context The project contributes to Busan's architectural landscape by demonstrating how mixed-use buildings can mediate between different urban conditions. Its location near Haeundae, a major tourist destination, adds significance to the design's contextual response. The building serves as a transition point between Busan's modern transportation infrastructure and its historic residential neighborhoods, setting a precedent for future developments. ## Architectural Significance This project represents an innovative approach to urban mixed-use architecture in South Korea. By rejecting conventional defensive postures, U.GA Architects has created a model for engaging with challenging urban sites. The permeable filter concept could influence future designs in dense Asian cities where noise and privacy are constant concerns. The project's completion will be closely watched by the architectural community. ## Sources covering this story - https://www.archdaily.com/1184999/jh-gwangan-mixed-use-building-uga-architects — --- _Summary written by Brifing from the original reporting.
