Here's what I did. I wanted a little storage space as well so it is bigger than need be. It's built elevated for ease of maintenance, to keep the pump up out of water (standing water can occur in this area of my property) and to keep critters from burrowing underneath to make homes. To insure good ventilation, the floor is constructed with spaces between each board and the side walls only go up as far as required to get under the eaves. BTW, you can buy small pump enclosures with ventilation fans built in. You can see an enclosure like that in my pics actually sitting inside the pump house.
Bill, I like your cabinet a lot. I think I will go this direction but mine will have to be totally enclosed around here or I will have wasp nests galore.
