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

The document titled "Office-to-Residential Conversions: Case studies from Tuath Housing" is published by The Housing Agency, a government body in Ireland that collaborates with various stakeholders to deliver housing solutions. The report is authored by Nicola Turley and aims to share insights regarding innovative solutions in housing, particularly focusing on the conversion of vacant commercial properties into residential units. This initiative responds to increasing housing demands while addressing the rising rates of commercial vacancy.

The report highlights the growing housing need in Ireland, with over 57,842 households assessed as needing social housing support as of November 2022. Dublin City has the highest demand, with 11,793 households on the waiting list. Concurrently, commercial vacancy rates have steadily increased, with a national rate reaching a 10-year high of 14.1% by June 2023. This situation presents an opportunity for repurposing vacant commercial spaces to meet housing needs, which can significantly reduce carbon emissions compared to new builds.

Recent changes in planning regulations have facilitated the conversion of commercial buildings into residential use. The Planning and Development Act (Exempted Development) Regulations 2022 allows for productive re-use of qualifying vacant buildings, emphasizing sustainability in housing development. The report notes that repurposing existing buildings can save up to 73% in embodied carbon compared to demolition and rebuilding, aligning with Ireland's Climate Action Plan objectives.

Tuath Housing's case studies include the conversion of the Plaza Building in Park West Business Park to 86 social housing homes, and Springville House in Cork, which now accommodates 35 social tenants. Both sites were selected due to high housing demand and the potential for efficient use of existing infrastructure. The report outlines the collaborative efforts among Tuath Housing, local authorities, and development partners to successfully execute these projects.

Three key actions were critical for the success of these conversions: collaboration with local authorities, innovative solutions to planning challenges, and consideration of tenant needs in the design process. As a result, 121 new homes were delivered, with Park West Plaza achieving an average unit cost of €309,000 and Springville House at €353,000. Improved energy ratings were also noted, with many apartments achieving ratings between A2 and B2.

The conversions have fostered a sense of community, with amenities such as community centers and play areas enhancing social interaction among residents. Feedback from tenants has been overwhelmingly positive, highlighting the quality of living and the support received from Tuath Housing. Challenges encountered during the projects included financial risks and the need for design adaptations to meet residential requirements.

The report concludes that office-to-residential conversions present a sustainable solution, particularly given the central locations of many vacant commercial properties. The success of Tuath Housing's projects may serve as a model for future developments across Europe, contributing to environmental sustainability and addressing housing shortages in urban areas.
