The building is clad with a mix of distinctive rusty and green metal sheets, similar to that of surrounding structures. A wayfinding sign pointing towards Valentine Detective Agency hangs next to the front door. On the southern façade is an unlocked door and large swaths of fabric are hung up between the greenhouse building and those across the street, creating a canopy. A single chimney is located on the roof.
Inside, plants are grown in the center and far edges of the dimly lit room. On the western end of the main room is a single extractor fan on the rear wall. Several mist sprayers are located near the plants, alongside wooden boards and bare soil on the ground.
Four tato plants, three mutfruit plants, and three wild mutfruit plants are cultivated within. On the western end of the main room is a single extractor fan on the rear wall. Scattered around are various tools amidst a few junk items.
The Diamond City greenhouse appears only in Fallout 4.
