The Secret of Land Plots: How to Read a Master Plan and Discover "Gold" Where Others See Bush

Our Valuation Approach: Before putting a plot of land on the market, our technical team requests or consults the Master Plan and the PDM (Municipal Master Plan) regulations. We create a preliminary "Mass Study" (a simple 3D sketch) that shows the buyer exactly what fits there: "This is where a 4-bedroom house with a swimming pool and underground garage fits." By making the abstract potential tangible in concrete square meters, we eliminate doubt and defend the maximum price per buildable square

For the average investor, a plot of land is just a piece of earth. For us at Royal House, a plot of land is a mathematical equation defined by the Municipal Master Plan (PDM). The difference between selling a plot of land for R$50,000 or R$150,000 often lies in an incorrect interpretation of urban planning indices.

Diving into Technical Indices: It's not enough to ask "is it possible to build on it?". You need to calculate the exact volume:

Land Use Index (Iu): This is the profit multiplier. If your plot is 1,000m² and the Iu is 0.6, it means you can build 600m² of gross building area (GBA) above ground. But be aware: basements for parking generally don't count towards this index, which is a construction "bonus" that many owners forget to value when selling.

Impermeability Index (Ii): Defines how much soil you must leave free for rainwater to infiltrate. If the Ii is 70%, it means that 30% of the land must be garden or natural soil. Ignoring this leads to projects being rejected by the City Council and sales being canceled.

Building Implementation Polygon and Setbacks: The rules regarding "views" and distances to neighbors (generally 3 to 5 meters) can make a narrow plot unviable, even if it has a building index.
