Typical Block - Eixample (Ensanche)

The Eixample plan proposed a square shaped block of 113.3m (372ft), with chamfered corners at 45 degrees, and three typical block layouts. The blocks would have only 50% of their plot ratio constructed with perimeter coverage, the remaining left for central patios or gardens that would offer public open space as well as appropriate light and ventilation to the plots. A maximum height of 20m (65ft), or four stories, was also established and coincided with the typical street width of the plan.

During implementation, however, the plan suffered many transformations. The typical blocks initially with an open layout became closed, and the courtyards were built up rather than remaining as open space. Changing ordinances eventually allowed for buildings to grow in height and depth, considerably increasing the density of the plan. Consequently, many of the Eixample blocks today have varying building forms, which reveal the evolution of ordinances over time.

The block selected as a case study was chosen since it contains buildings representative of these various ordinances. Using plans, sections and aerial images, a 3D massing model was generated and used to calculate the Gross Floor Area (GFA) and Floor Area Ratio (FAR) of the selected block. "
