Office-to-Residential Conversions: Case studies from Tuath Housing

The Housing Agency, a government body dedicated to improving housing solutions in Ireland, published a report detailing innovative office-to-residential conversion projects undertaken by Tuath Housing. This initiative responds to the pressing need for social housing amid rising commercial vacancy rates, which have reached a ten-year high, with nearly 30,000 vacant commercial units recorded across Ireland as of June 2023.

The report highlights the increasing vacancy rates in commercial properties since 2018, particularly exacerbated by shifts in working patterns towards remote and hybrid models. In Dublin, the commercial vacancy rate is at 13.1%, contributing to a national rate of 14.1%. The report underscores the urgency for sustainable solutions to repurpose these vacant spaces into residential units.

According to the Summary of Social Housing Assessments, over 57,000 households are in need of social housing support, with Dublin City reporting the highest demand. The pressure to provide adequate housing solutions is critical, particularly for vulnerable populations.

Recent changes in planning regulations, particularly the Planning and Development Act (Exempted Development) Regulations 2022, facilitate the conversion of commercial buildings into residential spaces. This act extends exemptions for eligible properties until December 31, 2025, promoting the efficient use of existing structures while addressing housing shortages.

Repurposing vacant buildings can significantly reduce embodied carbon emissions, with potential savings of up to 73% compared to demolition and new construction. The report cites international examples, including successful conversion initiatives in Canada and New York City, demonstrating the viability and benefits of such projects.

Tuath Housing has successfully converted two properties: Park West Plaza in Dublin, transforming long-vacant office blocks into 86 apartments, and Springville House in Cork, repurposing a vacant office building into 35 social homes. Both projects are designed to meet high sustainability standards while addressing immediate housing needs.

Collaboration between Tuath Housing, local authorities, and developers was crucial for the success of these conversions. Engaging with future tenants during the design process ensured that the residences met their needs and expectations, fostering a sense of community.

The conversions have resulted in 121 new homes, with Park West Plaza fully occupied and providing housing for over 200 individuals previously on the waiting list. The average cost per unit in Park West Plaza was €309,000, significantly lower than typical new build costs, while the developments achieved high energy ratings, contributing to lower utility bills for residents.

The report concludes that office-to-residential conversions can serve as a sustainable housing solution across Europe. With many commercial properties at risk of obsolescence, such projects present a viable avenue for addressing housing shortages while promoting environmental sustainability. Tuath Housing aims to replicate these successful models in other areas, advocating for innovative measures to enhance housing provision in urban centers.
