planing to post the next 4 tomorrow.... south side elevation, south corner, section and inside the envelope...
This is a rough set up of the Axo...explaining the relationship whole to part - part to whole of the envelope. I'm planing to further show single frames like the one here on the top and how they are inhabited and change. This is what the top part of the AXO should cover .... 
light
I was setting up the column/flat north facade of the envelope to start with.... and also articulated the ground a bit ... were there is a descending staircase that gradually lead down towards the inside .... were I'm planing to test some water reflections tomorrow for the rendering... second image shows the articulation of the column and how the it touches the ground....WIP....
Why
The project is not interested in
Barcelona gets interesting as site because of 2 different reasons- first it offers a very rigid, repetitive, background setting / the white ground/ which is for me the grid – and second as a reference to Mies, and the famous Barcelona pavilion- another white building on white ground- as it is reconstructed and mainly experienced through photographs and media presence.
The specific block I choose is determined by these 2 factors. It is positioned in a relative middle position along the mirror achsis that is determined by the grand via and two significant round abouts. Espanya and Placa de Tetuan.
My project proposal operates in a constant reference to Mies, and I want it to be read like this but it also claims to become its own design position through the introduction of the contemporary building type notion of the building envelope.
I am working on the drawing of the unfolded envelope now, showing the 4 different elevations and corner conditions and the changing density/ articulation in regard to the background of the surrounding block facades.
