Union Investment has commenced the extensive redevelopment of 4/5 Grand Canal Square, the former Dublin headquarters of Meta and one of the city’s most recognisable waterfront office buildings.

Construction works, led by Walls following a competitive tender process, began this week with the redevelopment being managed by Lafferty. The scheme is targeting completion for early 2027 with an estimated construction value in the order of €70,000,000.

The 18-month programme aims to transform the building into 250,000 sq ft of premium, sustainability-led workspace at the heart of Dublin’s South Docklands. Savills and Cushman & Wakefield have been appointed as joint letting agents.

The scheme plans to deliver enhanced public realm and landscaped external spaces at street level, creating a benefit for the wider community as well as occupiers. Savills said 4/5 Grand Canal Square is the only speculative new office scheme targeting delivery in 2027, making it a unique opportunity for future-focused occupiers.

"By retaining the existing structure, and reimagining it to the very highest sustainability standards, we are setting a new benchmark for low-carbon development in Dublin," said Asset Manager for Union Investment, Seb Wilson.

"With its exceptional location, premium amenity offering, and best-in-class environmental credentials, we believe 4/5 Grand Canal Square will be one of the most attractive workplaces in Europe when it completes in 2027."
