It took us (wife, daughter and myself) several hours in the span of a couple of weeks to finish the model. Everything in the box picture is inside in the form of pieces, raw parts and blueprints for fabric cuts. The manual is sufficient guide to complete the project, but the scope of the work required may look overwhelming. If you plan ahead and review the photos on the manual and box you can implement some modifications that may suit your preferences better. We decided to enhance the realism of the bathroom adding a toilet and a lavatory and changing the layout to accommodate these items (see photos). I designed and 3d-printed these (if you want the STL file I can provide it so let me know) and painted some parts to go with the theme.
