At Somerleyton Road, the existing fan house had to be demolished and re-built with existing air paths re-routed and new service rooms built within the existing structure. The existing fan house and main building wall were structurally linked requiring new wind post strengthening works to allow for full demolition and commencement of new building works. The main structure consisted of three separate tower areas for two new fans / cowlings, with internal vertical access ladders and removable floor plates at maintenance lifting zones. The external face of the building was brick clad with horizontal aesthetic feature steels to the 3 rd floor with continuous rain-water louvre system above to the underside of the roof. The roof was constructed of 3no segmented sections profile roof sheets and overlapping / co-ordinated flashings and gutters for later removal for fan replacement if required. The roof structure incorporated steel safety balustrades with access gained to the roof via vertical ladder and roof hatch.
