Services decide the fit-out
Container rooms and cabins can look simple on a drawing, but power, water, ventilation, insulation and drainage need routes before walls and finishes hide everything.
Early map
Draw where cables, pipes, vents, access panels, tanks, batteries and heaters might live. Then check what needs specialist review before any finish layer is installed.
Review note
Container projects can involve planning, structure, condensation, fire and electrical risk. Treat this as project planning, not a construction tutorial.
