Crude outbuilding

The crossword question is asking for a four-letter word that means a simple and usually small, rough, and often temporary building or shelter used for storage or as a workshop. The answer is SHED, which fits the description perfectly. A shed is typically made of simple wooden material and is often used to store gardening tools, bicycles, or other equipment. It is also used as a workspace to undertake various crafts, hobbies, or repairs. Its crude construction and simple nature make it an ideal solution for those who require some extra storage or workspace.
