Current structure
The interrogation of the current roof structure is vital for further developments of vertical extension. Because of the pitched roof wood structure, a new structural system has to be implemented to host the vertical extension. Simultaneously the sketches are testing out the idea of internal/external insulation and continuity or lack there of with the floor above.

The current wooden structure spans 14 meters and is spaced out roughly every 3.7m. at the structural grid points of concrete reinforcement in the walls. The structure is roughly 3.5 meters tall from top to bottom, however, it hangs at around 1.2 meters into the theatre space (above 2nd floor wall height), and the rest is an extension on the roof.
The first option is the cold-formed open web steel truss. Although the truss is slender regardless of heavy loading it is not an ideal solution because this type of structure has to be continuous with vertical support elements in order to be fully functional. Meaning steel columns would have to be used alongside the current concrete structure. Which is not financially viable or environmentally friendly.
Current roof structure
A new structural system is heavily important for safety and sustainability factors. As stated in previous pages the building is not insulated; thereby, if insulating internally the roof finishes would have to be removed, additional joists and trusses would have to be added to fixate the insulation boards and because the structure is bent it would be slightly more expensive. Additionally, the frame is assumingly not in a great state, while the extension above the theatre space is not used or maintained; thereby, the removal of these features is crucial for the theatre to reopen its doors.
New proposal detail
In this instance, insulation is done on the outside face behind the brick finish. This would mean that in order to maintain a brick facade a current building face would have to be torn down and replaced after being insulated. This is a direct juxtaposition of the vision for my Phase 4 proposal as I intend to maintain the historic facade.
