Land and buildings are immovable properties. But that is not where the question is significant. The question becomes complicated when we extend the meaning of immovable property to include things which are embedded or fastened to earth, commonly known as “fixtures”.
Fixtures may be done to civic structures – for example, doors or windows to buildings; fixtures may also arise in case of variety of plant, machinery, equipment, installations, such as furnaces, boilers, towers, and so on.
To describe it in more detail, immovable property includes land, buildings, hereditary allowances, rights to way, lights, ferries, fisheries or any other benefit which arises out of land, and things attached to the earth or permanently fastened to anything which is attached to the earth.
It does not include standing timber, growing crops, nor grass. It includes the right to collect rent, life interest in the income of the immovable property, a right of way, a fishery, or a lease of land.
