Please explain separately below 3 categories of land can be revalued without any issue or not?

An owner of a company wants to sell his company to a listed company. He wants some advice regarding the possibility of revaluing some or all the land assets to better reflect their current value in the balance sheet. Some assets were acquired many years ago and are still recorded at cost. He believes increasing these asset values will bolster the balance sheet. And the lands he owned fall under 3 categories.

1. Orchards (at several locations) that produce apples for sale via the Hobart fresh produce market or for use in the production of apple juice 2. Land located next to the main orchard, where apple juice production and storage takes place in a building located there 3. An unused parcel of land on a hillside overlooking ________________ Valley (acquired with the intention of building a weekend visitor centre for orchard tours, upmarket apple-based products, coffee shop and on-site accommodation for tourists).
