Comparison of architecture projects in slope
What is a sloping terrain?
A sloping terrain is a terrain that has an inclination with respect to a horizontal plane. This slope can be slight or extreme, and its presence has a considerable influence on how the architectural design will be approached.
Classification of slopes according to their inclination
Slopes are commonly classified into three categories:
Gentle slope: up to 10% slope.
Moderate slope: between 10% and 20%.
Steep slope: greater than 20%.
Building on a sloping site presents technical and logistical challenges, but it also provides opportunities to design with panoramic views and harmonious integration with the landscape.
Below, we present a hypothetical case of a 600 m² house on two levels, located on a 500 m² lot with a 30% slope, to help you make the best decision.
Option 1: Elevated Platform with Supporting Structure
The first solution in this example, is to develop an elevated platform supported by a structure of at least 5 levels, with prices between $15,000 and $20,000 MXN per m², due to the use of materials such as concrete and steel, and the need for specialized engineering, skilled labor and heavy machinery. The total budget for a 600 m² home is estimated between $9,000,000 and $12,000,000 MXN, including high long-term maintenance costs.
Advantages:
Provides a flat surface, facilitating design and accessibility.
Disadvantages:
High construction cost (between $9,000,000,000 and $12,000,000 MXN).
Greater environmental impact and need for continuous maintenance.
Option 2: Site-Adapted Housing
Adapting the house to the natural slope of the land with a stepped design reduces construction costs to approximately $9,000 - $11,000 MXN per m², due to the reduced need for complex structures and expensive materials. This approach also improves integration with the surrounding environment and energy efficiency. The estimated total cost for a 600 m² home is $5,400,000 - $6,600,000 MXN.
Advantages:
Lower construction cost (between $5,400,000 and $6,600,000 MXN).
Greater integration with the natural environment and better energy efficiency.
Taking advantage of views.
Savings by using prefabricated structures.
Disadvantages:
More complex design.
Conclusion:
Building a house adapted to the natural slope of the land is more economical and sustainable than an elevated platform. Although the platform offers a flat surface, its high cost and greater environmental impact make it less viable. Adapting to the terrain, although more complex in design, reduces costs and improves integration with the environment, being the most advisable option.
