I am looking for a word to describe the products or solutions to problems that are made at a very low cost, often home-made or by a very small organization. The products or solutions perform their function very well, but lack the aesthetics found in major brands or finished products at retail stores designed just for that purpose.
- hand bags that are reasonably strong and functional, only a lot less attractive compared to expensive ones
- a home-made camera mount built by a few pieces of wood, glues and rubber bands
- blocking sunlight from the window with aluminum sheets
EDIT: There have been a few suggestions with "hack" and "improvise". However I do not wish to convey the meaning that the solution is temporary or rushed under time pressure. The key point is low cost and sacrificing elegance, decorations which are unnecessary to make it functional. The goal is cost-effective. I think "utilitarian" comes pretty close.
