Overview of service

ORS provided Civil and Structural Engineering services for the redevelopment of The Plaza, Park West, Dublin 12, on behalf of Harcourt Developments.

The project involved the conversion of two long-vacant office buildings into high-quality residential accommodation, supporting Dublin City Council’s housing objectives while delivering much-needed homes within the city. As one of Ireland’s first large-scale office-to-residential retrofit developments, the scheme demonstrates the potential of adaptive reuse to create sustainable, modern housing.

ORS delivered comprehensive Civil and Structural Engineering services, including detailed structural assessments, retrofit design, and construction-stage support. Working within the existing precast concrete structures, the team successfully integrated new residential layouts, additional storeys and upgraded circulation systems while maximising the reuse of the existing buildings.

Project Outcome

Acting as Civil and Structural Consulting Engineers, ORS was responsible for the structural design and coordination of the redevelopment throughout the project lifecycle. The primary objective was to transform two redundant commercial buildings into high-quality residential accommodation while delivering practical, durable and sustainable engineering solutions.

Completed in 2022, the €26 million development delivered 86 social housing units, providing homes for more than 200 people. Through close collaboration with the client, contractor and wider design team, the project was successfully delivered while balancing the constraints of the existing structures with modern residential, accessibility and acoustic standards.

The redevelopment also delivers significant environmental benefits through the retention and reuse of the existing buildings, reducing embodied carbon while incorporating energy-efficient systems, including heat recovery ventilation and photovoltaic solar panels.

Challenges & Solutions

The redevelopment presented a number of complex engineering challenges associated with adapting existing precast concrete office buildings for residential use. Extensive structural investigations, surveying and material testing were undertaken to assess the condition and capacity of the existing frame, enabling the redesign of floor layouts, new stair cores, lift extensions and the addition of a new penthouse level.

Close coordination between the structural, architectural and MEP design teams was essential to successfully integrate the new residential layouts within the existing buildings while ensuring compliance with current building regulations and modern residential performance standards.

These challenges were successfully addressed through detailed structural analysis, collaborative design and innovative retrofit solutions that maximised the reuse of the existing structures. The completed development demonstrates ORS’s expertise in delivering complex refurbishment and adaptive reuse projects, creating sustainable residential developments while extending the life of existing buildings.
