Threadneedle House Refurbishment

Unex Group

Unex Group appointed Lindum to carry out a major refurbishment of this 19th Century building to create office accommodation and associated car parking areas.

Threadneedle House was originally constructed as a linen store for GNER (Great North Eastern Railway), with approximately 1920m² of space and a clear internal height of 7m, the building had more recently been used as a furniture outlet.

Transforming the building included the installation of an intermediate floor level throughout the whole area to create 850m² of high spec office space and an impressive feature helical staircase greets you as you enter the glazed lobby area.

To create the additional floor, cellular steel beams spanning over 10m were constructed between existing masonry walls and internal cast iron columns. Due to the age of the building, a series of geotechnical investigations had to be carried out first to establish the extent and depth of foundations to ensure there was the capacity to bear the additional load.

Other works to the building envelope included re-roofing to incorporate additional insulation, replacement of all windows and sand blasting of the original masonry walls.
