Though home renovation costs are mostly about local labor costs for tradesmen. I suppose I could spend an ungodly amount in a kitchen on super-premium appliances but more likely the bulk of the cost is masons, electricians, plumbers, carpenters, the local shop putting together the cabinets/counters/etc. You can also save a lot of money by being selective as opposed to hiring someone to do a complete makeover.
