Of course, building a desk is also an existing option, and can actually be profitable. But it all comes down to what kind of desk you are looking for, and whether it requires expert skills to design. For example, it is much more practical to build a standard, wooden desk rather than getting a store-bought one. But this wouldn’t be the case for building a multi-tiered desk, for which you would require exceptional carpentry skills, not to mention the cost of the materials and the risks involved. There are YouTube videos on making your own desk that rounds off to cost about $100. In the Indian context, it will be cheaper to buy a desk from a furniture store.
