Seoul’s Strategic Expansion of Rooftop Gardens to Combat Urban Heat
Table of Contents
Seoul is proactively addressing the challenges of urban heat islands and limited green space with a important expansion of its rooftop garden program. This actionable initiative aims to transform unused rooftop areas into vibrant gardens and relaxing community spaces for residents.
New Gardens Planned for 2025
By the close of this year, six additional rooftop gardens will be completed across the South Korean capital. These include installations at Boramae hospital, adding 2,227 square meters of new garden and rest areas to both public and private buildings.
Earlier this year, projects were successfully completed at Wolgye Library in Nowon-gu, Yega Daycare Center in Eunpyeong-gu, and the Onjo Daewang Culture and Sports Center in Gangdong-gu, collectively adding 1,013 square meters of green space.
Further expansions are slated for Boramae Hospital in Dongjak-gu, Seoul Metro’s Gunja Depot in Seongdong-gu, and Hanmaeum Church in Jungnang-gu. These spaces are designed to serve diverse needs, from providing respite for patients and caregivers to creating staff lounges and community gathering spots.
A Two-Decade Commitment to Green Infrastructure
Since its inception in 2002, Seoul’s rooftop garden program has outfitted 785 buildings with green roofs, creating approximately 330,000 square meters of green space. This is equivalent to the area of 45 standard soccer fields.
Did You Know?
Rooftop gardens can reduce building temperatures by as much as 3 to 4 degrees Celsius,mitigating the urban heat island effect.
The benefits extend beyond temperature regulation. These gardens also provide vital insulation during colder months, enhance urban biodiversity, and contribute to the overall well-being of Seoul’s citizens. Research from the Environmental Protection Agency highlights the positive correlation between access to green spaces and improved mental health (EPA, 2023).
Financial Incentives for Private Building Owners
The city is committed to supporting the continued growth of the rooftop garden program. Currently, Seoul offers to cover up to 70 percent of the installation costs for private buildings that are selected through a competitive application process.
Pro Tip:
Consider native plant species when designing your rooftop garden to maximize biodiversity and minimize maintenance.
| Year | Buildings Equipped | Total Green Space (㎡) | Equivalent Area |
|---|---|---|---|
| 2002-2025 | 785 | 330,000 | 45 Soccer Fields |
| 2025 (New Projects) | 6 | 3,240 | N/A |
What impact do you think these rooftop gardens will have on Seoul’s air quality? And how might this model be replicated in other densely populated cities around the world?
The Growing Trend of Urban Greening
Seoul’s initiative is part of a broader global movement toward urban greening. Cities worldwide are increasingly recognizing the importance of integrating nature into urban environments to address climate change, improve public health, and enhance quality of life. Strategies include green roofs, vertical gardens, urban forests, and the creation of green corridors.The benefits of urban greening are well-documented, ranging from reduced stormwater runoff to increased property values (UNEP, 2022).
