I need to see your plan IMO a shed is best hidden and where it works best for use . I never put my BBQ away in the winter we BBQ all winter where I live in Canada nd honestly I have no clue as to what a 2 storey shed attached to a home would look like . So post pics of the architects plans please.

Why don't you build some sort of storage closet on each floor accessible from the outside on each level instead of tacking something onto the house design after the fact.

In the right conditions, and with the right engineering, and architecture, this may be work. The wrong conditions, bad engineering and architecture and it could be a disaster.

With that said and your kitchen on the 2nd floor it may be an ideal place to design additional sq footage for an elevator /dumb waiter type of system to move groceries, etc from the car to the kitchen without messing up the rest of the house. From a safety point of view it would give an escape path if the inside exit from the kitchen area were blocked ie fire.

At picture and topo map of the area would help with getting ideas

In my area we call that a covered deck with storage below. You can get as fancy as you want...

My mom has a storage box on her deck that holds cushions year round and puts a canvas cover over the BBQ. I have a covered deck and grill year round. We got rid of our lawns but used to store the lawn mower in the garage, my neighbor has cute little storage house in the yard for his tools as his garage is taken up by all his kids stuff... lol

Hello Colin,

Has the town or municipality where this home is to be built been determined yet? If it has, you should obtain a copy of their Building Code. The Building Code will contain all sorts of rules that you must comply with, some of which may seem counter-intuitive. Also, do you intend to hire a builder? A good builder is familiar with local building codes and he (or she) can supply guidance on a variety of matters. Selecting exactly where to build your house involves many things.

Why not have an area/room that is inside the house that is only accessible from the 2nd floor balcony.
