Kochi apartments must be placed where the sunlight falls on them directly. Skylight - the latest addition to the list of comforts - is a kind of window built into the roof and provides natural light. Aesthetically uplifting, it reduces eyestrain and power consumption and may increase productivity. It is a case of old reborn into a new device. In the olden days, a traditional artefact in rural houses was a large opening in the roof through which the sunlight would bear down on the space. An instant advantage, though few would venture into the space braving the heat, was that the floor would dry up and look tidy.

The obvious inference is that on a cloudy day it serves little purpose. It is commonly made from glass, glass composites, plastics and plastics composites. It is treated with dyes to reduce light transmission or by adding a reflective surface. Like all ingredients it has pros and cons. An advantage of glass is its durability, hardness, high light transmission and rigidity. Glass can be made more resistant to breakage by heat-treating it to increase its thickness and combining it with reinforcing materials. Plastic materials are much lighter in weight, and are resistant to shattering, so they pose only a minimal safety hazard. The skylight is another medium of transmitting natural light and with venetian blinds or any window covering can keep the house adequately lit to one's satisfaction. To ward off the possibility of excess, intense heat pervading the room one is given the right choice of fabric for greater light diffusion.
