Adaptive Reuse: Retrofitting the Honolulu Real Estate Crisis
Adaptive reuse, the process of repurposing underused buildings for new functions, is gaining momentum in Honolulu as a strategic response to two pressing issues: the surge in commercial real estate vacancies and a severe housing shortage. This blog explores how Honolulu is leveraging adaptive reuse to not only address its urban and housing challenges but also to reinvent its architectural heritage and community spaces.
The Growing Trend of Adaptive Reuse in Honolulu
Nationally, the commercial real estate sector is grappling with high vacancy rates, a trend exacerbated by changing work habits post-pandemic. On Oahu, this situation presents unique opportunities for innovation in adaptive reuse, turning empty offices and commercial spaces into vibrant residential, retail, or mixed-use developments.
The vast majority of Oahu island is governed by city ordinances that limit building height restrictions, focusing the density of high rise buidldings and business zoning to the city of heart of Honolulu. Downtown Honolulu is the economic powerhouse of Hawaii, hosting numerous businesses, government offices, and international corporations and as a result but for many years, Downtown Honolulu has lacked the vibrancy and "soul" that characterizes a lively urban neighborhood.
This image starkly contrasts with the exciting developments in nearby Kakaako, where new condominiums and mixed-use developments have sprung up, offering a modern urban living experience. Critics of these new Kakaako condos will cite the lack of affordable housing inventory for local residents, given that many of these buildings see prices well into the $1M - $3M range.
However, the winds of change could begin to blow through Downtown Honolulu, with concerted efforts underway to breathe new life into this historic area, including but not limited to some of the most recent revitalization projects:
- Modea - a condo-conversion of the former Davies Pacific Center office building by The Avalon Group. This new Honolulu condo plans to bring 352 residential units to market by 2025 with prices estimated to start in the $400,000's.
- In 2021, we saw the old Remington College building converted to a 104-room boutique hotel; the AC Marriot Honolulu.
- We should also see the 86 year old Wo Fat Chop Suey building transformed into a new boutique hotel in Chinatown in 2024.
- Douglas Emmett recently converted a 25-story office building in 500 rental units at 1132 Bishop Street.
Opportunities created by Adapative Reuse
Adaptive reuse construction presents a multifaceted opportunity to blend environmental sustainability with economic growth and cultural preservation. By repurposing existing buildings, this approach conserves natural resources, reduces waste, and minimizes the carbon footprint associated with new constructions, thereby contributing significantly to environmental conservation. Carl Elefante, former president of the American Institute of Architects, said it best in his National Trust's Forum Journal article; "The greenest building...is one that is already built."

Economically, it offers developers and investors cost savings, potential tax benefits, and the chance to stimulate local economies through the revitalization of neighborhoods and increase in property values. Culturally, adaptive reuse serves as a bridge between the past and the present, allowing communities to retain their historical essence while accommodating contemporary needs, fostering a sense of identity and continuity.
Moreover, adaptive reuse sparks innovation in design and architecture by challenging professionals to integrate modern functionalities into old structures, creating unique and appealing spaces. It promotes urban renewal, reduces urban sprawl, and makes efficient use of existing infrastructure. These projects not only cater to a wide range of uses, enhancing community engagement and social cohesion, but also offer businesses a distinctive positioning in the market.
Additionally, the integration of sustainable design principles and modern energy-saving technologies improves the energy efficiency of repurposed buildings, leading to long-term operational savings. Through these diverse benefits, adaptive reuse stands out as a sustainable, economically viable, and culturally enriching strategy for future development.
Challenges facing Adaptive Reuse Construction
Assuming a developer perserveres through limitations related to local zoning laws, preservation requirements, hazardous materials, and environmental assessments:
Structural issues: Older buildings may not meet current building codes or standards, requiring significant structural upgrades. This can include reinforcing the building to withstand earthquakes or updating it to comply with modern safety and accessibility standards.
Energy inefficiency: Many older buildings are not energy-efficient, with outdated HVAC systems, poor insulation, and single-pane windows. Upgrading these systems to meet contemporary energy standards while preserving the building's character can be challenging.
Design limitations: Adapting an existing structure to a new purpose often requires creative solutions to overcome design limitations. This can include issues with natural light, ceiling heights, or the layout, which may not suit the new use without significant alterations.
Integration with modern technology: Integrating modern technology and infrastructure (like high-speed internet, modern electrical systems, and plumbing) into an older building without compromising its structural integrity or aesthetic can be difficult.
- Building Permit Delays: Honolulu has long been plagued by excruciating delays in its permit processes with 12-18mo wait times becoming the rule and not the exception.
Despite it's challenges, successful projects in Honolulu demonstrate the potential for adaptive reuse to transform urban spaces innovatively:
The Role of Technology in Adaptive Reuse
Technology significantly enhances the adaptive reuse of buildings by enabling precise planning, efficient execution, and innovative solutions to complex challenges. Through Building Information Modeling (BIM), 3D laser scanning, and photogrammetry, professionals can create accurate digital representations of existing structures, facilitating detailed assessment and informed decision-making.
These tools help in visualizing the potential transformations, assessing structural integrity, and integrating modern sustainability and energy efficiency standards. Virtual and augmented reality further allow for immersive previews of proposed changes, engaging stakeholders and refining designs before physical work begins.
On the sustainability front, technology plays a pivotal role by enabling the integration of smart building systems and the application of sustainability analysis software, ensuring that adaptive reuse projects meet contemporary environmental standards. Structural analysis and simulation software provide critical insights for reinforcing and upgrading buildings to comply with current codes, while prefabrication and modular construction techniques offer efficient ways to add new elements with minimal disruption.
Together, these technological advancements make adaptive reuse a more feasible and attractive option for revitalizing old buildings, blending historical preservation with modern functionality and efficiency.
The Future of Adaptive Reuse in Honolulu
Looking ahead, adaptive reuse is poised to become an integral part of Honolulu's urban development strategy.
Adaptive reuse represents a forward-thinking solution to some of Honolulu's most significant challenges. By reimagining the potential of existing spaces, Honolulu can pave the way for a more sustainable, inclusive, and vibrant urban future.
