**TBA / Density / C Int / P Ver** are all stats of your design visa. Short description:

**TBA** is the Total Build Area of all the floors of the basic and supplementary construction on and above the terrain, including the entire areas of balconies, loggias and terraces in the above the ground floors calculated by their outer outlines. The TBA does NOT include:

- The floors below the terrain.
- The built areas in the under-roof spaces of buildings, provide they are storage rooms.

**Density of the construction** is the ratio of the [sum of the built areas of all the basic and supplementing constructions in the plot **(BA)**] to the [area of the plot] – expressed by percent.

**Intensity of the construction** is the ratio of the [TBA of all the buildings in the land plot] to the [area of the plot] – expressed by absolute number.

**Percent of green land** of the plot (P Ver) is the ratio of the [area under the natural vegetation] to the [area of the plot] – expressed by percent.

Formulas and an Example (let’s assume we have the following information on our visa):

- The area of the land plot is 300 sq. m.
- We are allowed 50% density
- We are allowed 2.5 C Int
- We have P Ver no less than 30%

We want to find the allowed TBA and the BA of our future building. This means that:

BA/300 = 50/100 => BA = 150 => our building could be erected on a maximum of 150sq.m.

TBA/300 = 2.5 => TBA = 750 => the total build area will have a maximum of 750 sq. m.

P Ver/300 = 30/100 => P Ver = 90 => we must have at least 90 sq. m. of vegetation (green land) in the land plot.
