It sounds like someone is excited about a particular design or structure they found on FESHOP, possibly imagining it as their own garden or backyard shed. The enthusiasm expressed with "Love this" and "this could be our shed!" suggests they see potential in the design and are considering it for a future project. The "X" at the end adds a friendly, affectionate touch to the message.
If this is a reference to a specific item or design from a legitimate site called FESHOP, it could be related to home improvement, design inspiration, or something they found online that they want to implement.
