PHASE 1 _ DATA COLLECTION
1 Plaza Lesseps Plaza Lesseps is located in Barcelona, in between Gracia and SarriĂ -Sant Gervasi districts. Historically, Plaza Lesseps has been amended on numerous occasions, now resulting in an urban space that fails to materialize divided between scale. The lack of urban quality we attribute, in part, to the surrounding buildings. Specifically the walls and facades that are in an unfinished condition. Plaza Lesseps
Plaza Lesseps
2 The Unfinished Undefined walls that build the urban environment. Each wall is defined by its position, height, width and by its area and/ or volume.
unbuilt volume
blind facade

3 Transferring analog to digital data After mapping all the blind walls of the surroundings, to quantify them, they were digitally processed to treat them as objects of information.
Sourroundings buildings that defines the Plaza
Unfinished walls in the sourroundings
Unfinished walls
In orther to structure the unfinished walls information, the following rules were created: - Each unfinished wall will be representing as a point in its site position. - The X,Y will be in the center and the Z coordinate in the highest position. - The diameter will be the surface square meters value.
Conversion of the Unfinished walls in DataPoints. Sphere: x, y, z = space coordinates diameter = wall square meters

Unfinished walls area visualization The image below shows the total amount of all the unfinished walls areas. The intensity of the color tells us the area with the highest amount of unfinished surface, this followed as to analyze the internal space of the plaza, this basic visualization was made in Processing.

4 Visual Analysis In order to undestand the incidence of the Unfinished square meters on the Plaza, this has been divided in a grid of 300 points (new dataPoints), and the Unfinished walls have been organized per orientation (North, South, East and West). After this, we calculated how many square meters per orientation are incident in each datapoint. This process was made with Ecotect Visualization Analisys, where a spreadsheet with the points and values data was exported to Processing.

5 Unfinished wall position + Visual Analysis In order to categorize, organize and clean the values, a process to generate what is defined as Nodes was done based in the following rules: - Each Unfinished wall point generates, per orientation, a 50 meters ratio. - Each Unfinished wall point connects with a DataPoint that has at least one other connection with other Unfinished wall point. - The DataPoints with an area less than 2 are not considered (The squared meters of each DataPoints where previously Remaped from 1 to 8). - The Height of each DataPoint is the addition of the square meters incidence per orientation.

PHASE 2 _ ARCHITECTURAL PROGRAM
1 Plaza Lesseps equipments and uses To buid a relationship between the given architectural program* and Plaza Lesseps programatic context, the Plaza was analyzed in three different program types: - Public - Semi- Public - Private * architectural program given by the Studio
Municipal Library Bus Stop Primary Education Parking Restaurant Farmacy Vocational Training Metro L3
Public programs distributed around the Plaza
Public uses
Semi-Public uses
Private uses
2 Plaza Lesseps and DataScape analysis The relationship of the actual public uses of Plaza Lesseps with the Nodes DataScape, creates a tendency of wich are the areas that might have a tendency for being densified. The densification is divided in three categories depending on the type of program.
public uses semi-public uses private uses
low density position medium density position high density position

PHASE 3 _ POPULATION
1 Generative process: Population rules After the site uses in relation with the Nodes DataScape and the new program relationships and square meteres analysis, in order to intervening the site for further development to achieve volumetric and spatial morphologies, three population rules were created in a generative process with Processing to generate Point Clouds over the Nodes DataScape.
Rule 1 Population for Private uses.

Best population for Public uses
Populations catalog parameters but changing their values.
The resulting population points are exported to Rhino. This process is not linear, is a back foward process between Processing and Rhinoceros, where all the clouds are tested with several ways of connecting the points and evaluate them in square meters in orden to accomplish the program requirements. Public program Final Point Clouds

PHASE 4 _ DIGITAL TECTONICS
1 Generative process: Population rules After evaluating the previous generated points, 5 rules of how to connect this points were created in order to define Polystructures. Per Polystructure, nine different tectonics were created, each one was evaluated in terms of program requierements and spatial conditions.

PHASE 5 _ RULES APPLICATION
From the previous catalog, the rules 3.3 were selectected. In order to understand the global context of the Plaza in relation with a further morphological development, the rules were applyed to all the PointClouds. As each PointCloud have their own boundaries, the parametric process is adapted in order to work properly.
