as per my understanding, u means that the entity has invested in other company by giving building as purchase consideration.I would give answer on this assumption.
As per Provisions of IFRS,he purchase consideration for an acquisition (business combination) is the sum of:
the fair values, at the acquisition date, of the assets transferred by the
acquirer, such as cash , Building etc
So the building shall be removed from balance sheet of parent company and building shall be shown in consolidated account at fair value
