Of course, there is a minimum budget. We calculate it based on the technical specifications provided by the customer. On average, you can focus on 130,000 "turnkeys", that is, all work, materials, lamps, kitchen, furniture. If you do not have the required amount, but want to order a project from me, I recommend limiting yourself to a technical project, and spending the saved money, for example, on high-quality Italian cuisine.
I also take projects with a low budget, but an interesting technical specification, in which we can realize some of our fantasies.
