SPSecurity.RunWithElevatedPrivileges(delegate()

               using (SPSite site = new SPSite("http://sharepoint2013:40000/sites/customsite/"))
               {
                   using (SPWeb newWeb = site.OpenWeb())

                       SPWebTemplate SiteTemplate = null;
                       SPWebTemplateCollection templateCollection = newWeb.GetAvailableWebTemplates(1033, true);

                       foreach (SPWebTemplate wt in templateCollection)
