I had to go the other way. I extended out the front 28 feet. The
foundation size of the whole building is now 20 x 50.

I went for flexibility.
In the nominally 20 x 20 parking garage I have 12 string-switched sockets
(with grounded outlets, since sometimes I might not want to step over/under
a cord to one of the 6 duplex wall outlets).
In the nominally 20 x 30 heated shop I have 18 string-switched sockets (with
grounded outlets, since sometimes I might not want to step over/under a cord
to one of the 16 duplex wall outlets). Over each of the two workbenches I
have a 4-foot double fluorescent fixture.
The flexibility is that I only have to turn on what lights I need. I can
put whatever wattage bulb I like in any of the fixtures. If I decide to put
up more fluorescent lighting later, I can just hang it up and plug it in.

1/3 of a watt. Volts times amps equals watts.
14 bulbs x 1/3 watt = 4.67 watts.

Memory not good, but I think 12 gauge for 20 amp, and 14 guage for 15 amp.
