Refurbishment of Glazed Door & Screen, Co. Dublin

Project Story: Leeson Lane Office Development The Leeson Lane Office Development is a landmark achievement in combining heritage architecture with high-performance building design. The project included the construction of a new 7-storey over-basement government office building, integrated with the sensitive refurbishment of Spruce House, a former dispensary.

The two structures connect at the rear, creating a flexible, multi-occupancy headquarters. A central element was the restoration of the historic Leeson Place Laneway, preserving architectural character while enhancing the public realm. The building meets nZEB (nearly Zero Energy Building) standards and complies fully with the European Energy Performance of Buildings Directive.

Passive strategies including natural ventilation and daylighting were incorporated through atrium design and layout. A major scope of the project was the supply and installation of Schüco Jansen steel-framed glazing systems and doors, delivered by Irish Door Systems Ltd (IDS).

These played a key role in achieving fire safety, acoustic insulation, energy performance, and design integration across new and heritage areas.

Key Challenges Overcome: Coordination with OPW, Duggan Brothers, and the design team to meet structural and fire standards Manual handling and installation of large bespoke units under restricted access and tight timelines Precision alignment of glazing systems for fire performance, acoustic control, and visual continuity Integration of access control, automation, and fire-rated components in off-site preassembly Systems Used: Janisol 2 EI30, C4 NR EI60, C4 Rebated EI90/EI120, Economy 60, Pyroguard fire glass, FACE Automation SW80, BEA Flat scan sensors, and Hotron touchless switches.

This project exemplifies sustainable innovation and heritage sensitivity. IDS’s delivery and continued support position Leeson Lane as a model for modern public buildings — and a worthy Irish Steel Awards nominee.
