    Usually used to level up flooring from the kitchen to living room, or from the balcony to living. The idea is to make the floor level the same height so that there is no more drop. Most of the times this is reserved for making the space look bigger by creating an extension of space from living to balcony.
    When a door opening is needed, the designer will determine whether the wall needs to be hacked. If so, a door opening may be created, simply by hacking a non-load bearing wall.
    This means to cover up a former door opening by using either hollow blocks or other materials and finish it with plaster.
    Usually for kitchen or bathrooms. The concrete support is to house the sink or stove. It will be finished off with tiles or just plain cement screeding.
    This is also known as plinth. The plinth acts as a skirting from the flooring so that the cabinet will not be in contact with the flooring. For example, in the case of wet flooring.
    It acts as a base for the shower screen. Otherwise it may also be used to deviate water from the shower area to the rest of the bathroom.
    A membrane known as waterproofing will be needed to apply on to the surface before tiles are laid. This is necessary as water may seep into the apartment downstairs if it is not applied.
