Apparently the House of the Year show was axed in January and isn't related to the recent cull. By the sounds of what you said it had probably reached the end of its shelf life anyway.

Perhaps more indicative of it's woes is the axing of House of the Year - shown under the Grand Designs brand for many years. Must admit though creatively I found the last series was essentially showing us versions of things we'd seen over the year.
