This image, titled "BUILDING ON SLOPED SITE," illustrates different approaches to constructing a building on uneven terrain, specifically contrasting a method that involves extensive earthwork with one that preserves the natural slope.
Let's break down the four panels:
Top Left Panel: Original Sloped Site
* Description: This panel shows the initial condition of a sloped piece of land. There are natural contours, existing vegetation (a palm tree), and some smaller plants or rocks.
* Implied Challenge: Building directly on such a slope without modification would be difficult, as traditional flat foundations aren't suitable.
Top Right Panel: Excavated and Refill Method (✗)
* Description: This panel illustrates a common, but often less ideal, approach to dealing with a slope.
* Process:
* A significant portion of the hillside is "EXCAVATED" (cut away) to create a flat building pad.
* The excavated material might then be used for "REFILL" (added back) in other areas to level out the site, or it might be transported away.
* A retaining wall (shown here as a stacked stone wall) is built to hold back the cut earth and create a level platform.
* Implied Consequences: This method involves substantial disturbance to the natural landscape, requires significant earthmoving equipment, and can be costly. It often leads to a less integrated look with the surrounding topography.
Bottom Left Panel: Natural Slope & Vegetation Preserved (✓ - Conceptual Approach)
* Description: This panel acts as a conceptual bridge, showing a house-like outline on a natural slope.
* Key Principle: It highlights the idea of respecting the existing terrain. The text "NATURAL SLOPE & VEGETATION PRESERVED" emphasizes a design philosophy that minimizes disturbance.
* Visual Elements: The slope, existing trees, and a "STREET" at the bottom are maintained, indicating a desire to adapt the structure to the land rather than forcing the land to adapt to the structure.
Bottom Right Panel: Integrated Building with Retaining Wall (✓ - Solution)
* Description: This panel depicts a completed building that successfully integrates with the sloped site by following the principles from the bottom left.
* Key Features of Integration:
* Stepped Foundation/Structure: The building is designed with multiple levels or a stepped foundation that follows the natural grade of the land.
* "RETAINING WALL": A retaining wall is still used, but it's typically less massive than in the "excavated and refill" scenario, and it's incorporated as part of the building's design, often forming the base of a lower level.
* Preserved Landscape: The existing "STREET" level is maintained, and the natural "NATURAL SLOPE & VEGETATION PRESERVED" is evident above the building, with the palm tree still in its original position relative to the higher ground.
* Advantages: This approach often leads to more sustainable construction, reduced environmental impact, potentially lower earthwork costs, and a building that feels more "at one" with its surroundings. It also often allows for multi-level living spaces that take advantage of views.
Overall Message: The image advocates for designing buildings on sloped sites in a way that minimizes excavation and disturbance to the natural landscape, often by adapting the building's form to the existing contours and strategically using retaining walls to create functional levels while preserving the site's natural beauty.
