had a little job we finished up last month....I think it came to around $38,000 for the kitchen (residential)...this is just labor/lighting/panel (no appliances) ....
fellow had a real need for excess...walk in frig, walkin wine cellar, walkin beer vault, multiple beer taps, 3 sinks (1 on each side of the kitchen + island), think we had close to 30 circuits in there, two different French stoves (gas, but needing electronic ignition) - believe the general charged him over $250,000 for his part.
