After completing the concrete roof on the first section, the adobe bricks were brought out to build up the external and internal walls on the middle section, the utility room, the second bathroom (photo below) and Ed's bedroom.
Of course, another lintel had to be constructed over the full length windows in Ed's room.
Here you can see Florensio and Mariano building the archway linking the living room to the corridor, 
and filling in the gaps between the arched door leading into Ed's room.
