Then out in the middle of the floor area have an island table either fixed or on locking or jack down casters so you can work on the model from any direction.
That's what I did. A bench for the heavier work & a building table on castors that I can move around.
At my last house I had limited space so I made the table with a metal frame so when I was finished
building I could roll it in front of my car with the table overhanging the bonnet so, in reality, it took up no
room at all in the garage.
No storage under the building table though.
When I lay up a wing or fuselage I have a separate building board which sits on the table. - John.
