Deepwater Lighthouse

Lacking inspiration for my town, I decided to build other things in my world. The lighthouse is managed by the lighthouse keeper, an old man who passess his time by fishing and growing wheat. This four-story lighthouse can contain about 30 people in case bandits raid the nearby village, and contain a dinning hall, kitchens, living quarters, and an oil-based light. The floors are connected by a staircase revolving around the walls of the lighthouse, with doors seperating the staircase from each floor. Despite the fact bandits hadn't attacked the village in the last few years, the lighthouse keeper keeps it in perfect condition and cleans it every so often.
This is my first submission, so I hope you guys like it :)
