The heating pipes and ventilation ducts are neatly tucked away and run through the cornice around the module to the units.
The plumbing and drainage systems for the sanitary facilities are integrated in SAM. Thanks to the smart design, you don't see the pipes but they are easily accessible for maintenance.
The main electrical service panel is perfectly concealed in SAM. Through this point, all devices and lighting are supplied with power. Most switches are located on the module, but additional (wireless) switches can also be installed elsewhere.
