Wihlborgs Fastigheter is the leading commercial property company in the Oresund region. The company was originally founded in Malmo in 1924 by master builder O P Wihlborg. Activities grew over the years and eventually comprised properties in Stockholm in addition to those around Oresund. On 9 May 2005, the properties in Stockholm and the Oresund region were separated. The property stock in Stockholm remained with the parent company and, at the same time, changed its name to Fabege AB. The Oresund property stock was incorporated in a new company which retained the name Wihlborgs Fastigheter. On 23 May 2005, Wihlborgs Fastigheter AB was listed on the Stockholm stock exchange's O list. Since then the company has grown from 197 properties with a market value of SEK 7.9 billion during 2005 to 253 properties and a value of SEK 20.5 billion as at 30 June 2013. Wihlborgs' offices and stock of properties are now in selected areas of the market in Malmo, Lund, Helsingborg and Copenhagen. The property portfolio has developed and steadily improved through sales, purchases and refinement.
