To complete a remodel, it requires a lot of work behind the scenes. Which encompasses many different avenues, including: finalizing the scope of work, shopping for selections, ordering materials, mapping out the lead times, deliveries, schedules, inspections, and so on.
This list does not change from remodel to remodel. It is the same for a kitchen remodel, bathroom remodel, basement remodel, or even a whole house remodel. The same list does not change from a 10k project to a 300k project.
