STRUCTURE
As proposed building volume should provide a corridor for the tram line, the main load bearing system is a skeleton of columns and beams. Comparison of building materials suitable for this system was made to provide best performance.
STEEL
+ light construction + quick assembly
- transports vibration
- acoustically bad- needs permanent maintenance if used in exterior- needs fire resistant coverage
CONCRETE
- high load on foundation- RCC- time consuming, expensive + pre cast concrete- cheaper, quick assembly + bigger building mass extinguish vibration + better acoustic performance + does not need permanent maintenance after construction + min fire resistance of 1 hour
As a result of comparison prefabricated concrete was taken as the main construction material of columns, beams and slabs due to the best acoustic performance as well as sufficient impact noise insulation and vibration resistance, load bearing ability, and high level of fire resistance. Column grid of the building is appropriate for free floor plan configuration and allows various types of apartments. RCC concrete is used for cantilever parts construction.

Structural scheme
Hereby structural scheme of the building is a main load bearing and spatially stable concrete skeleton( 8m x 10m grid) by prefabricated elements, filled with prefabricated timber exterior and interior walls. Wood was selected for wall construction because of the low sound transmittance, sufficient air permeability level allowing natural exchange of air between spaces and unique surfaces and textures. page 138
