Of course, our lawn mower is electric.
So another add on...you know, in addition to pulling out the random outlet in the dining room floor, was to put an outlet on the exterior of the house.
For now, we just did the one in the back yard. It would be good to have one on the front too - but there wasn't an easy access point because of the level of finishing downstairs. I don't have a breakdown of what each element cost but I do have the electric bill that I'll share with you guys soon.
