WEEK 9 - STUDIO JOURNALThe axonometric view clearly shows the length of the bricks, which the 2D detail drawing could not show. As previously stated, the blockwork is from scoria rock and the header of the blocks have dimensions 140mm x 190mm. Each brick also has a length of 390mm.

The concrete slab must have been precast and reinforced with steel before delivering on site where it is laid down. The blockwork masonry was delivery block by block, where it was installed with mortar. The glass roof would have been installed last.Pros/ConsThe concrete slab is strong in compression, can withstand heavy loads, has a low maintenance cost and is durable. However, the concrete is also prone to degredation and because the blockwork is an existing wall, it will be old and require maintenance. Also, the glass roof is brittle and prone to shattering.Sustainability & Environmental AnalysisThe mass production of cement and masonry from factories is a large contributor to greenhouse gas emissions which is degrading the environment. These materials also require water during manufacture so it has a lot of embodies energy and water. However, these materials, including the thermal insulation are 100% recyclable and can be reused again in the future. The glass roof is not re-usable as it cannot be re-molded or changes once it has set.

Thin sarking boards are used, shown in the axonometric view to prevent water from penetrating the building beyond the exterior masonry wall.
