You have to be kidding. Design and build?. All Plastic. Dimensions 18" high x 11.5 " wide x 9.5" Deep. you put in standard size garbage bags that have draw ties on top when you remove the garbage back. Handle swings up and you push down the rectangle inside that compacts everything. Easy to keep clean. Sits in galley area. We have had one that we purchased from A RV Store in Florida back in 2004 for around $30 and still working like a charm. I will try and find the name of the unit and the supplier and post it as soon as possible.
