The shed started as an 8' x 8' barn type design. I increased it to a 8' x 16' shed with a 10' center and used an exterior metal door for the entrance. I actually used the half walls of the original building to construct the side walls. The outside is stuccoed and the roof is architectural shingles with a roof vent. The inside is finished with shelves and plenty of area to store outdoor tools. Total cost was around $2,000 and used exclusively Ryobi 18 volt and 110 volt tools.
