The project, which commenced in January 2024 and was completed in June 2026, represents a significant repositioning of the 45,000 sq. ft. office building, one of the most prominent properties within Blanchardstown Corporate Park.
The extensive programme of works was designed to enhance the building’s environmental performance, improve the day-to-day occupier experience and ensure that Block One continues to meet the evolving requirements of modern businesses.
The upgrade included the complete replacement of the building’s glazing, the installation of new mechanical and electrical systems, the modernisation of common areas and toilets, and the delivery of enhanced end-of-trip facilities. Significant improvements were also made to the building’s overall energy efficiency and operational performance.
Most notably, the works have improved Block One’s Building Energy Rating from a C-rated BER to an A-rated BER, marking a substantial advancement in the building’s sustainability, efficiency and long-term asset performance.
Occupying a prominent position within Blanchardstown Corporate Park, Block One has been transformed into a modern, efficient and flexible workplace environment. The upgraded building now offers enhanced comfort, improved amenities and modernised systems designed to support both occupiers and visitors.
Delivering a project of this scale within a live, occupied building presented a particular challenge. Regus remained in occupation throughout the works, while JJ Rhatigan & Company moved into the building during the upgrade programme. Channor extends its thanks to the project team, contractors and occupiers for their patience, collaboration and professionalism throughout the process.
The repositioning of Block One is already generating increased occupier demand. Regus has expanded its presence in the building by taking an additional 5,000 sq. ft. of accommodation, while JJ Rhatigan & Company has recently opened its new Dublin office at Block One. A further letting is also currently at the legal stage.
Darren Harrison, Chief Executive Officer of Channor Real Estate Group, said:
“The completion of the Block One upgrade is an important milestone for Channor and for Blanchardstown Corporate Park. The project reflects our continued commitment to investing in our existing portfolio, improving sustainability performance and delivering high-quality, modern workspace for occupiers.
“It is particularly rewarding to see the building’s repositioning already translating into increased demand and further leasing activity.”
The project reflects Channor’s broader approach to long-term ownership and active asset management. By investing in the quality, performance and occupier experience of its existing buildings, Channor continues to strengthen Blanchardstown Corporate Park’s position as a leading business location in Dublin and Ireland.
A 10,000 sq. ft. floorplate remains available to let on the third floor of Block One, together with a 3,000 sq. ft. penthouse offering access to a roof garden. The available accommodation is being marketed by Paul Hipwell and Deborah Mahon of Lisney Ireland.
Channor would also like to acknowledge the project team involved in delivering the works, including TOT Architects, TQM Fitout, Eden Windoor Ltd and Sean Murphy of Channor Real Estate Group.
