Flax House is a five-story Victorian building with red brick, warehouse style construction, located on Adelaide Street, in the Linen Quarter of Belfast, Northern Ireland.

Originally home to handkerchief manufacturer, McBride & Williams, the warehouse building was designed by Young & Mackenzie and built in the 1906-07 period. Straidorn Properties acquired 83-91 Adelaide Street, in 2016, after it had been derelict for 30 years.

Flax House

The refurbished and fully extended Flax House now offers five floors of exceptional Grade A office space, with each floor plate typically configured to provide around 5597 sq. ft. lettable space. 

AET Flexible Space’s underfloor air conditioning, with full underfloor supply, and underfloor return air was specified so that the warehouse loft ceilings could be left exposed, highlighting the retained features and building characteristics.

CAM-C downflow units and TU4 Fantiles installed

Flax House is the second building on Adelaide Street to make use of plenum air conditioning. A total of 11 CAM-C downflow units and 128 TU4 Fantiles from AET Flexible Space were supplied for the five-story building.

Completed in 2018, the Flax House building is now fully let, each floor with a different tenant, and the businesses include the modern, tech-focused firms, which the developer has looked to attract.
