Abstract: A hybrid building system using metal studs and brick ties in a timber framed building. The metal stud comprises an elongated metal section including two flanges joined by a web. The elongated metal section may be a C-section or a Z-section. The metal stud comprises foldable tabs at the top and bottom of the stud, a plurality of fastener holes along its length, service apertures along its length, brick tie fixing holes, a plurality of foldable lining spikes along its length and a wall lining sheet support tab at the lower end of said stud. The primary advantage of the invention is that there is an opportunity to utilize the desirable qualities of a steel stud with timber frames, which are more widely used, to create an improved building frame system.
