Dual-Purpose Man Cave
With all of the bedrooms in our home filled up one at a time by our three kiddos, we needed more space for my home office. We built a wall in our 2-car garage, dividing it in half, and converted this half into a home office. The front half of the garage is still available for storage.
Although primarily a home office, I added an attic ventilation fan that allows to enjoy an occasional cigar while visiting with clients and friends.
