Oh no! I think I described this very poorly. Here is our inspiration & I think this would be approximately the same size as our intended shed. I think tracks like above would be difficult to install & keep clear, so I'm trying to brainstorm different ways to build this concept.
We are planning on paving a spot out front to place a shed against our house & underneath our kitchen window. Our proposed two options for building are:
#1: Having the sliding part come out the wide way, like a trundle bed & unlike our inspiration. The bikes would be stored similarly to the inspiration picture but I plan to install some stands to keep them upright & not leaning on each other. The "trundle"/sliding part would be mounted on heavy duty drawer slides & would be approximately 4' x 6'. I'm a little worried about pulling it out so far that it will sag since we'll have 45+ lbs of bikes in there.
#2: Having the sliding part come out the same way as the inspiration pic (long way). This means the sliding part would have to be pulled out approx. 6 feet, which would make drawer slides difficult. I think installing a track & wheels would be a pain, but I like the idea of having individual drawers for each bike for ease of use instead of one big storage area.
Did that make anything more clear? Unfortunately, we're limited on height because this needs to fit underneath our windows, which are about 4.5 feet off the ground. We thought about doing a basic shed in the same spot, but constantly shuffling three bikes in & out of a small space would drive us all crazy pretty soon.
