Firstly, for those who have just bought a house, interior planning can be quite challenging due to the abundance of various choices, budgets, timelines, and design decisions. However, if you follow our flat interior design checklist, you will not only avoid making expensive mistakes but you will also make sure that the home you choose is beautiful, functional, and future-ready.
This 3BHK flat interior design checklist is designed to help you go through the process from starting to understand your space platform and continuing through to the final execution.
