The first idea was a detached workshop / garage ..... however, in that configuration it would not pass the "spousal approval" stage.... so I have added a poolhouse and pool into the plans.
Ideally I would like to go two story with the bathroom, changeroom, balcony and guest suite / party area upstairs (woodshop, machineshop, and garage on lower level). I was reviewing my local ordinances last night and noticed a detail that states that any detached building must maintain the character of the house - in my case a brick 1 story ranch design.... have to look into that in more detail because aesthetics would obviously matter more .
Thanks for the offer to scratch plans/ dimensions but not necessary - get back to work on your "garage" - I can't wait to see it completed.
